Due to the shortage of the fossil fuels, such as the petroleum, natural gas, and mineral coal, the power under-supply, and serious urban pollution, the fuel cell technology has become a hot issue of research and development in the field of global energy. The fuel cell is an electrochemical device in which the sustainable supply of chemical energies in the fuel and oxidants can be continuously converted into electrical energy and heat energy, and has no intermediate combustion process. Because of the advanta...
