PEMFC电源系统的开发与应用

The Exploitation and Application of PEMFC Power Supply System

质子交换膜燃料电池(PEMFC)作为第四代发电技术的典范,具有高效和环境友好两大突出优点,受到世界各国政府的极大关注和各大公司的青睐,被广泛认为是较有实力与传统内燃机竞争的替代动力源。文章介绍了质子交换膜燃料电池的工作机理、系统组成及其在电源方面的应用现状,同时提出质子交换膜燃料电池在发展及商业化等方面所面临的问题。

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.
