Fuel cell
I. Technical Overview
Fuel Cell (Fuel Cell) working principle is very simple, chemical Shui through electrolysis to generate hydrogen and oxygen, fuel cells and vice versa, is the production of water by combining hydrogen and oxygen, releasing energy at the same time. Hydrogen fuel cells is the main material consumption, and some directly to bring hydrogen fuel cells, the use of aluminum high pressure cylinders. Methanol or gasoline also make useful materials Laptop battery, through re-engineering technology to generate hydrogen.
A variety of fuel cell so that the reaction of hydrogen and oxygen conditions and in different ways, including proton exchange membrane (PEM) fuel cell with low temperature (70 ℃), suitable for use in electric vehicles and Latitude D620 battery. Proton exchange membrane coated with precious metal catalyst, can produce hydrogen and oxygen ions through the membrane into water, and generate electricity. In the electrochemical reaction in a Discount laptop battery voltage of only 1V generated, it should be composed of hundreds of pieces of the battery pack to generate electricity KW-class and as a driving force of motor vehicles.
Second, the status quo and development trend of domestic and foreign
The world’s industrialized countries have fuel cells Discount laptop batteries as an important strategic objective, dumping huge amounts of money for research, the United States, Canada, Germany, Japan, the cost of their study are hundreds of millions of dollars. At present, proton exchange membrane fuel cell bus trial in the vessels and, but the high prices is the fuel of vehicles 5 to 10 times.
By further reducing the cost to improve reliability, before and after 2003 a large number of applications in the car. Only those domestic colleges and universities, Now sony is have been researching for the fuel cells. scientific research units have just begun a pilot study, compared with foreign investment is very small, only in this strategic area of the level of follow-up study abroad.
