The purpose of this thesis is to study fuel cells. They convert chemical energy directly into electrical energy with high efficiency and low emmission of pollutants. This thesis provides an overview of fuel cell technology.The basic working principle of fuel cells and the basic fuel cell system components are introduced in this thesis.
The properties, advantages, disadvantages and applications of six different kinds of fuel cells are introduced. Then the efficiency of each fuel cell is provided. The EFOY 1600 fuel cell experiment shows that fuel cells are not affected by the temperature. Another experiment of Hydrocar shows that the efficiency of fuel cell is almost the same at different voltages. Finally, the history and future of fuel cell represent the development of fuel cells in China and foreign countries.
The results show that the fuel cell can convert chemical energy into electrical energy without combution. Some energy is lost in the form of heat during the pocess, however, this heat can be utilized for heating or cooling, and it is not wasted.
