Abstract:As the representative of the fourth generation of generating electricity, proton exchange membrane fuel cell(PEMFC) possesses two outstanding strong points, high efficiency and amity for environment. Thus it is paid attention by the governments and shows preference by big corporations all over the world. It is widely recognized as the new generation of power source to compete with internal combustion engine. This article mainly describes the function principle of the PEMFC, the composition of fuel cell system, and the utilization of PEMFC on power supply system. This article finally outlines the problems of PEMFC development and commercialization.
