固体氧化物燃料电池的现状和未来

State-of-art and future of solid oxide fuel cell

简述了国外固体氧化物燃料电池 (SOFC)的发展状况及近年来取得的重要进展。首先对SOFC的工作原理进行了简单的介绍 ,然后对于传统的以氢为燃料的SOFC ,重点从成本和技术两个方面 ,比较了高温和中温反应条件下 ,燃料电池阳极、阴极、电解质和层间介质所用材质的选取 ;对于近年发展起来的以碳氢化合物为燃料的SOFC ,重点介绍了碳氢化合物氧化的间接法和直接法两种工艺流程和研究现状。最后针对以氢为燃料的高温和中温SOFC及碳氢化合物为燃料的SOFC的研究和技术现状 。

The state of art of solid oxide fuel cell (SOFC) development at abroad and the important progresses made in recent years are reviewed in brief. The operating principle of SOFC is introduced firstly, and then the selections of anode, cathode, electrolyte and interconnect substance materials for the traditional SOFCs using H 2 as fuel at high temperature and moderate temperature are compared from the point of view of cost and technique. As for the SOFCs using hydrocarbon as fuel, the technological process of direct method and indirect method and the research status are introduced emphatically. At last, the state of arts of research and technique status of the SOFCs using H 2 as fuel for high and moderate temperature application and the SOFCs using hydrocarbon as fuel are prospected respectively.
