Survey of the Present Condition of Fuel Cell and Its Development Tendency Huang Shahua, Liu Zhijing*, Wang Keyi# (Department of Modern Physics, # Department of Precision Machinery and Precision Instrument University of Science and Technology of China, Hefei 230026) Abstract Fuel cell is an electricity generating device that converts chemical energy stored in the fuel and oxidizing agent directly into electrical energy. It does not pass through the thermal engine process, so it has high efficiency without being inhibited by the Carnot cycle. Nowadays, it has become a new electricity generating technology which many developed countries compete to develop. In this paper, the fuel cell's classification, working principle, survey of the development and its future tendency will be generally introduced.
