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.
