PEMFC電源系統的開發與應用

摘要：質子交換膜燃料電池(PEMFC)作為第四代發電技術的典范,具有高效和環境友好兩大突出優點,受到世界各國政府的極大關注和各大公司的青睞,被廣泛認為是較有實力與傳統內燃機競爭的替代動力源。文章介紹了質子交換膜燃料電池的工作機理、系統組成及其在電源方面的應用現狀，同時提出質子交換膜燃料電池在發展及商業化等方面所面臨的問題。 敘詞：質子交換膜，燃料電池，電源系統 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. Keyword：proton exchange membrane； fuel cell； power supply system
