金属支撑型固体氧化物燃料电池研究进展

Development of metal-supported SOFC

随着固体氧化物燃料电池(SOFC)向中低温发展,使得金属材料用于SOFC的关键组件成为可能。金属支撑型SOFC(MS-SOFC)是以金属或合金作为燃料电池支撑体的结构。相对于其他支撑型SOFC,MS-SOFC具有更好的导电能力和导热能力、较高的机械强度以及较低的成本,所以引起了研究人员的广泛关注。目前,MS-SOFC的结构呈多样化发展,支撑体、电极和电解质的材料及其制备工艺也不尽相同。本文介绍了不同结构的MS-SOFC的研究现状,评述了它们各自的制备工艺和存在的问题,并提出了目前MS-SOFC亟需解决的问题。

Developing of intermediate temperature （IT） and low temperature （LT） solid oxide fuel cell （SOFC） allows metal to be used as an appropriate material for SOFC. In consistant to other types of SOFCs, metal- supported SOFC （MS-SOFC） exhibits higher electrical and thermal conductivity, better mechanical strength and lower cost, and thereby has attracted more and more attentions. Recently, MS-SOFC has developed various structures and fabrication process of supporter, electrolyte and as well as the electrodes. In this paper, the state of the art of MS-SOFC and their fabrication process are reviewed and the key concerns on MS-SOFC are also put forward.
