The hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen. Its basic principle is the inverse reaction of electrolyte water. After the anode and cathode are provided with hydrogen and oxygen, the hydrogen is reacted through the anode outward diffusion and electrolyte, and the electrons are released to the cathode through the external load.
According to the Energy Storage International Summit, the application of hydrogen fuel cells in developed countries as a "zero emissions" clean energy in developed countries is accelerating. Japan will build 100 hydrogen refueling stations by 2015, and 13 have been built. The EU has recently passed the increase in fuel cell buses; the production model of modern car IX35 fuel cell vehicles has been offline in March 2012, and it is planned to 2015 2015 Mass production from the year. This shows that the fuel cell has really moved from the laboratory to industrialization, and it has zero pollution advantage compared to lithium batteries.
