Catalyst: A fuel cell system must be high efficiency and high specific energy. To obtain high efficiency and high specific energy, it is necessary to improve the gaseous fuel and oxidizer in the process of the electrode reaction, namely, research and development of efficient catalysts. ThinkPad T42 Series, ThinkPad T43, ThinkPad R50, ThinkPad R51 Series, FRU 08K8193,At present,IBM Laptop Battery, the use of other inexpensive and effective catalyst for the replacement of the precious metal catalyst to become one of the catalysts.

The feasibility of fuel cell

dell inspiron xps m1710 battery, so Western countries such as Japan, the United States and Europe have a fuel cell research and development program, China is also accelerating the process of fuel cell research, the development of fuel cells today nearly 200 years of history, which truly is a world wide attention in the 20th century, ThinkPad T42 Series,50's, from today, but also about 50 years, but fuel cell technology development is rapid.

Power gap calls for a new power technology

Portable electronic products in the global popularity of the increasing appearance of their products as well as the function of small light to the battery has become increasingly complicated and new challenges, and in addition to laptops, mobile phones and digital cameras, other products, there are also similar to the power supply gap . Existing rechargeable battery technology has matured, but the lithium-ion rechargeable battery capacity is not much room for improvement (less than 5% per year), in meeting growing energy demand will be much more difficult. But in the next few years is expected inside the existing battery technology will not be able to meet the growing portable electronics products of the energy demand,ThinkPad T43,new power technologies and products will be a huge market space and opportunities.

People's mobility more than ever before, and then expand the power of the gap. Notebook computer is the fastest growing areas, is expected shipments in 2006 to more than 50 million. Widespread adoption of Wi-Fi technology has actually cut off the shackles of Ethernet,ThinkPad T42 Series, ThinkPad T43, ThinkPad R50, ThinkPad R51 Series, FRU 08K8193, and users will be the last hope is the path to remove the AC power cable, which is even more to promote a new battery technology.

The development of fuel cells

Because of its high energy conversion efficiency, clean and pollution-free, modular structural advantages and strong, fuel cells become the target of concern to the industry, to meet the immediate needs of the revolutionary power, fuel cells become a really strong player preparation. As early as 1839, ThinkPad R50,British scientists made W Grove on the principle of generating hydrogen and oxygen reaction, which is the first hydrogen fuel cell (FC) model. So far fuel cells mainly four kinds of types, they are as shown in table 1.

More than four kinds of fuel cells have their own characteristics,ThinkPad T42 Series, ThinkPad T43, ThinkPad R50, ThinkPad R51 Series, FRU 08K8193, but also their different technical barriers and the development direction, but as a member of the fuel cell, they have the same general character, for which, combined with the characteristics of various types of batteries, fuel cells are summarized in the research and development should focus on several aspects.

Electrolyte membrane: H + only allows through, but did not break down the fuel does not allow infiltration of the past. Therefore, to study the electrolyte membrane including the proton conductivity of the electrolyte membrane, gas and other fuels to reduce the infiltration capacity, and enhance the redox and hydrolytic stability, improve the mechanical strength and thermal stability, in order to improve the surface properties and is suitable for catalyst combination. In addition, we must reduce costs and improve value for money.

Electrode: mostly due to fuel cell electrode as a gas electrode process, FRU 08K8193, we must use a special electrode structure - porous gas diffusion electrode to improve battery life than the power.

Fuel: Study of fuel is the fuel of choice. At present, fuel cell applications, the main use of H 2 and CH 3 OH. Research on the replacement of fuel, fuel cells will enable the development of more sustainable.

System Architecture: System structure of the final results of the fuel cell. Because of the small fuel cell or micro fuel cell will be used in conjunction with the integrated circuit, so the development of system architecture is limited. How to carry out high-density fuel cell assembly,ThinkPad T42 Series, ThinkPad T43, ThinkPad R50, ThinkPad R51 Series, FRU 08K8193, the realization of portable electronic devices in the application of fuel cells, has become one of research directions.

Catalyst: A fuel cell system must be high efficiency and high specific energy. To obtain high efficiency and high specific energy, it is necessary to improve the gaseous fuel and oxidizer in the process of the electrode reaction, namely, research and development of efficient catalysts. At present, the use of other inexpensive and effective catalyst for the replacement of the precious metal catalyst to become one of the catalysts.
