Human beings in order to make more effective use of energy, has been making unremitting efforts. The history of the use of energy, there have been several revolutionary changes each time changes are greatly promoted the development of our society. Secondary energy in the steam due to short transmission distance, it is difficult to store and the application is limited; electricity transmission faster, the transmission distance, but there is energy loss in the transmission process, difficult to store shortcomings; hydrogen both long-distance transmission. can facilitate the storage, and thus become the ideal energy of the twenty-first century, the twenty-first century is also known as a hydrogen century. Over the years people have been trying to find the energy efficiency of higher energy without polluting the environment, and thus lead to a fuel cell power generation technology. The fuel cell is not directly by the combustion process the fuel chemical energy converted into electrical energy, with the unique advantages of high energy conversion efficiency of the discharge of pollutants. The fuel cell by virtue of its unique advantages of application in various fields to accelerate the social development of society, and promote the social civilization. In this paper, the fuel cell technology, the principle of various types of fuel cells and their respective characteristics, and describes the applica
