Methanol fuel cell & multi-purpose portable solar

2004 to 2005 as the target market, the Japanese equipment manufacturers around the laptop battery and cell phone fuel cell engaged in a fierce competition to develop. Fujitsu Research Institute in the trial of this case for fuel cell laptops.Hp laptop battery Maximum output power of 15W, in the use of 300ml of methanol solution, they can drive the company's notebook computer "FMV-BIBLOMG55E" running from 8 to 10 hours. Since 2001 the Institute began in the materials before and after the Environmental Technology Institute of the fuel cell for mobile phone development, has made some in the outcome of the test products will be announced later. HP Pavilion ZV6000 Battery(hp zv6000 battery)
HP Pavilion DV1000 Battery(hp dv1000 battery), HP PF723A Battery, HP 367759-001 Battery, The test products released for notebook computers, but not solely on the development of personal computers for the goal. "Mobile phone and other mobile devices will be equipped with features such as television receivers, the power consumption will continue to improve. Naturally applies to the equipment, taking into account" (Fujitsu Research Institute of Materials Research Institute of Environmental Technology Research Department of the function of organic materials). Entering the practical stage, will be considered with the mobile phones, notebook computers and other joint business development.

The advantage of the introduction of the test products is promising to use high concentration methanol solution. In the original direct methanol fuel cell, if the supply of fuel very high concentration of methanol solution, the methanol will not react directly through the polymer electrolyte membrane, the occurrence of "infiltration (CrossOver) phenomenon." Therefore, at present, most of the set concentration of methanol solution at about 10%. Fujitsu Research Institute of the confirmation, even if the concentration of methanol solution to 30% toshiba battery, it did not happen due to infiltration of the phenomenon led to the problem of declining output. Due to high concentration of methanol can be used,HP Pavilion ZV6000 Battery(hp zv6000 battery) thus greatly improving the unit weight or unit volume of energy density.

In order to reduce the infiltration phenomenon, Fujitsu Research Institute has done a two-pronged effort. Polymer electrolyte membrane that is to change the composition of the material, HP Pavilion ZV6000 Battery(hp zv6000 battery)
HP Pavilion DV1000 Battery(hp dv1000 battery), HP PF723A Battery, HP 367759-001 Battery, as well as efforts in the electrode structure. The use of polymer electrolyte membrane material has aromatic structure of the main chain. The original widely used fluorinated resin as compared to the spatial structure of polymer is very different. "This kind of material to make polymer electrolyte membranes become rigid and detailed. Feel like on the stronger and engineering plastics. And also very strong polarity. Mission of methanol polymer electrolyte membrane had preventive effect of increased 5-fold" ( Fujitsu Research Institute). Through the use of such a polymer electrolyte membrane, even if the concentration of methanol kept at 30%, it did not happen due to the infiltration phenomenon caused by the phenomenon of decline in output power. Fujitsu Research Institute also said that "feeling can also continue to improve concentration. Has confirmed in 40% of work", but did not mention the use of methanol and, therefore, a high concentration of methanol is not clear how efficient the use of. battery.

In order to obtain such a polymer electrolyte membrane material, the Institute with the outside world in addition to factories and universities to conduct joint studies, also conducted its own internal development. Fujitsu Research Institute but did not publish the source of the materials used,HP Pavilion DV1000 Battery(hp dv1000 battery), and ultimately used to determine what kind of material did not.

In the electrode structure, the Au catalyst is said to improve the density of carbon black carrier. "Improving the density of the outer electrode. The result is compared with the original electrode makes the thinning. Au particles larger density, the physical structure also helps prevent the passage of methanol molecules" (Fujitsu Research Institute). For the realization of such a high-density, it is said the company will be fine Au particles to the diameter of 2 ~ 3nm.

Fujitsu Research Institute will present the concentration of methanol solution to 30%, but their goal is 50%. "30% is not enough. If you do not raise the 50 percent target is not" (Fujitsu Research Institute). Practical use of the target before and after 2005.

Fujitsu Research Institute in the development, HP Pavilion ZV6000 Battery(hp zv6000 battery)
HP Pavilion DV1000 Battery(hp dv1000 battery), HP PF723A Battery, HP 367759-001 Battery, it is also expressed at home and abroad to participate actively in the legal environment to promote the idea that "although progress has been made in the development, if imperfect legal provisions, in the application of obstacles still exist. For example, HP PF723A Battery,when the fuel cell with into the aircraft cabin? it is necessary to advance the preparatory work in this area. "

Add the use of methanol fuel solution. Solution penetrated into the lower part of the adoption of self-respect toshiba satellite m100 battery, toshiba satellite m105 battery, it reached the bottom of the fuel cell plate. Solution in methanol without added tools such as pumps, belonging to the passive type.

The products include the body (battery), solar cells, a variety of devices to connect the dedicated AC wire interface. Electricity generated by solar cells is stored in the body, the use of stored energy, the solar cells can be removed in order to carry. Capacity of the power can be stored 4.8Wh, equivalent to two ordinary phone battery. Output voltage of 3.8V ~ 8.5V, the maximum output power of 10W.

Part of solar cells using a single two large-size solar cell modules. Generating high-voltage generally is 7mm width of 15 battery modules in series to constitute a loop, but this will appear as part of the battery unit according to less than sunlight, or by an external impact damaged part of the battery unit of the circuit can not work. To avoid this problem using a single mode of NTT.

Removed after the solar cells can be placed on a hand

However, in SBC, the use of sunlight can be issued only voltage 0.1 ~ 0.4V or so.HP 367759-001 Battery, NTT has developed to this end will be about 0.1 ~ 0.4V low-voltage to 5V or so "very low input-voltage step-up technology." In order to achieve even a part of the plate can not generate electricity to other parts of the normal power generation, and will have the power stored in batteries on the body of the function, the entire solar cell modules are printed on the collection of the electrode power.

In addition, the "pockets of power," also called with the "MPPT" (Max Power Point Tracking) function. It can detect changes along with the light of current and voltage changes, it has been maintained at the highest state of power generation. "MTTP is a roof, etc. have been used in solar cells on large-scale practical use of technology, HP Pavilion ZV6000 Battery(hp zv6000 battery)
HP Pavilion DV1000 Battery(hp dv1000 battery), HP PF723A Battery, HP 367759-001 Battery, but because of the control chip power consumption is too large can not be used in the previous small-scale solar cells.'s" Power pockets "to streamline the functions of the MPPT successfully configure the function "(NTT Energy Research Institute of Environmental Systems Engineering, director of energy research fellow Masato Mino). NTT said that through these technical improvements, new product capabilities in power generation technology with the use of the original compared to the power-generating capacity, photoelectric conversion efficiency can be increased by about 1.5 times.

Contend with fuel cell vehicle

Speaking of a new generation of cars, the most powerful when the number of candidates in order to hydrogen-powered fuel cell vehicle laptop battery. However, there are many issues compared to the fuel cell vehicle,Hp laptop battery there are a number of new technologies and as a result of more realistic and compelling. This is the electric motor with the engine and the hybrid, as well as in Europe, promoting the popularization of the main diesel engine vehicles.

In these new technologies and intense competition for dominance in the competition when it unexpectedly From a surprise. This is the Mazda is developing a "hydrogen rotary engine" car.

To ¥ 5,000,000 each (about 384,000 yuan) for the target

Fuel cell vehicle is hydrogen and oxygen through a chemical reaction to obtain power, and Mazda's hydrogen engine is based on hydrogen-fueled internal combustion engine. The world dedicated to research and development of hydrogen engines only Mazda and BMW in Germany. Mazda since 1991, HP PM579A Battery, HP Pavilion DV4000 Battery(hp dv4000 battery) , HP Pavilion ZE2000 Battery(hp ze2000 battery), HP Presario M2000 Battery(compaq m2000 battery), has been engaged in the development of hydrogen engines. Up and down movement of the piston engine general it is difficult to control the combustion of hydrogen toshiba battery. However, HP PM579A Battery,Mazda's proud ---- let alone technology triangle rotating rotor rotary engine is very suitable for control of hydrogen combustion, hydrogen engine is Mazda eyes on this point.

"The goal is 3 to 4 years in the practical operation." In October last year, Mazda's president Hisakazu Imaki in Tokyo Motor Show this Declaration issued Zhuang, before the specific surface of the strategic plan. The next 2 years with a hydrogen engine will be the first to government agencies and enterprises to carry out video, then consider selling in the market. February next year will add an additional hydrogen Mazda headquarters facilities for the practical use to prepare. In addition, the need to spend huge sums of money from the fuel cell vehicle Mazda's largest shareholder - the United States responsible for the development of Ford, it can be wholeheartedly Mazda hydrogen rotary engine development. Rotor hydrogen car is the most important weapon to reduce costs. At present, such as Toyota and Honda are rented or sold to government agencies, such as fuel cell vehicle, but the body is said to vehicle prices in the ¥ 100,000,000 (about 7.69 million yuan) or more. Fuel cell vehicles as a key part, so that hydrogen and oxygen react chemically generate electricity, "battery pack" in terms of cost to occupy a large proportion of future development work still needs to invest heavily.

At the same time, hydrogen basic structure of the rotor of motor vehicles in April last year began selling sports car of the "RX-8" compared to almost no change. Just add an additional hydrogen to the combustion chamber of the injection device, placed in the trunk of the hydrogen storage tank and the hydrogen leak detection sensor can be.HP Pavilion DV4000 Battery(hp dv4000 battery) , Even the engine room, compared with an ordinary car is no different, you can use the original intact production equipment to reduce new investment.

RX-8 in the prices of ¥ 2,000,000 (about 150,000 yuan) from top to bottom, and "practical rotor of the hydrogen car will be the market price of about ¥ 5,000,000 in the objective to develop" (project development to promote this Investigator Zhanghong Kashiwagi). It is certain that the low supply prices will be fuel cell vehicles can not match.

Hybrid is also under consideration

Kashiwagi full of looking forward to the future: "Hydrogen is not a simple rotor 'convergence' petrol truck and a car battery technology. Hydrogen supply facilities in the future even if fuel cell cars have become the mainstream of the times, but also need to use, so the rotor hydrogen fuel car can be cell vehicles continue to coexist. "

However, the true hydrogen car to universal rotor that there are still some technical issue toshiba satellite m40 battery, toshiba satellite m45 battery. Rotor current development of hydrogen cars, hydrogen can only be added once traveling 70km. Although it could be combined with gasoline, in the practical aspects of the problem does not exist, but such a short distance or to undermine the significance of the next generation of engines. In addition, the use of gasoline can produce 210 horsepower at the power, and then switch to hydrogen is only about 110 horsepower, HP PM579A Battery, HP Pavilion DV4000 Battery(hp dv4000 battery) , HP Pavilion ZE2000 Battery(hp ze2000 battery), HP Presario M2000 Battery(compaq m2000 battery), a reduction of about half the horsepower. Even if these problems can be solved, but "still need to study hydrogen storage battery and the motor rotor and the combined hybrid system." (Okada and Mazda's executive director)

Rotor engine in the 90's have had to stop the development of endangered plight. HP Pavilion ZE2000 Battery(hp ze2000 battery),It difficult to cope with increasingly stringent environmental standards are the main reason. However, this is the rotor Mazda engine may become a new generation of environmental technology trump response.

Bottleneck in computer ¬ebook batteries

Bottleneck in computer & notebook batteries

With the progress of the notebook battery computer technology,dell laptop battery From a mobile office concept has already become a reality. In order to meet the needs of mobile and mainstream manufacturers are introducing more powerful, more stable system of ultra-thin notebooks. Used for this ultra-thin battery, RC107 Battery
Latitude D620 Battery, 312-0386 Battery, PC764 Battery,but because of the lack of electricity has become a new bottleneck in mobile office. And, in addition to persistent power, the battery is very expensive prices, and a piece of notebook batteries accounted for 10% of the overall price -15%, then an ultra-thin laptop battery should have the characteristics of what it mobile office to meet the demand? From the practical point of view we may wish to analyze the design of laptop battery standard.

Industry experts believe that time is of the battery. Ultra-thin notebook computers because of the thin body makes room for the installation of the toshiba battery becomes more limited, and the battery means to reduce the volume of the power supply even shorter time, not every ultra-thin notebook computers can be up to standard the battery life. At present, a common ultra-thin notebook battery time between 2-3 hours, a good brand can be achieved for about four hours, there are higher, such as NECS820 will be able to provide electricity five hours time, and if equipped with backup battery, the life of up to 11.8 hours. Moreover, the computer which is designed to extend the battery very thin flat-shaped, and its size and the fuselage in line with the expansion of the bottom of the chassis battery integrated with the fuselage,PC764 Battery, and fully maintained the smooth state of the fuselage.

High melting temperature carbonate and solid electrolyte type fuel cells dell battery, emissions of heat can also be used for the second generation. The use of waste heat for heating or combined together for power generation, fuel cell utilization efficiency up to 70% ~ 80%.

Flexibility. Fuel cell power generation device is composed of a number of basic units. A basic unit is a two folder electrolyte electrode plate. The basic unit will be assembled hundreds of them would constitute a battery pack, battery pack and then together to form a power station. Can be flexible depending on the needs of different size to the assembly of fuel cell power plant. The basic unit of fuel cell design standards can carry out large-scale pre-production, so the fuel cell power plant construction and low cost, short construction cycle. In addition, as a result of fuel-cell light weight, small size, high specific power, relatively easy to move up,Inspiron 1000 Battery, so it is particularly suitable in remote areas or islands to build power stations, or build a distributed power plant.

Fuel diversity. Although the fuel cell hydrogen is mainly the work of the material, but it can be used for fuel gas, methanol, liquefied petroleum gas and other hydrocarbons. According to the actual situation, in line with local conditions to use a different fuel, or combination of different fuel use, can reach local materials, to save resources.

Pollution-free. The main product of fuel cells is water, essentially non-emission of harmful gases, it is a very clean source of energy. It is reported that a number of fuel cell emissions of harmful gases in the United States national standards for environmental protection by two orders of magnitude lower. In addition, the fuel cell is a stationary power generation, has no mechanical transmission device,GD761 Battery, KD476 Battery, TD347 Battery
Inspiron 1000 Battery, only in the control system and other auxiliary devices have moving parts, thus it is the work of a small vibration, low noise.
