摘　　要：连接体是固体氧化物燃料电池(SOFC)中的关键组件,对连接体的高性能需求一直制约着SOFC的商业化发展。随着SOFC的运行温度降低到800℃以下,廉价的高温抗氧化金属连接体材料取代掺杂铬酸镧(LaCrO_(3))陶瓷的可能性大大增加。此外,为了优化连接体的性能,大量的导电/保护性涂层及新的复合材料也不断地涌现。综述了迄今为止连接体材料的发展现状,在对各种连接体材料以及涂层材料的性能和优缺点进行比较的同时,重点介绍了新开发连接体材料的研究进展,并对连接体材料的发展趋势进行了展望。Interconnect is a critical component in solid oxide fuel cell(SOFC).There is urgent demand to develop interconnect with high performance for SOFC stack commercialization.As the working temperature of SOFC decreasing to intermediate temperature(<800℃),high temperature oxidation resistant alloys instead of doped lanthanum chromite(LaCrO_(3))ceramic become promising candidate.Besides,to optimize the utilized performance of interconnect,a variety of conductive/protective coatings as well as advanced composites are studied.The present paper provided a critical review of the recent progress of interconnect materials for SOFC.For comparison of the advantages and disadvantages of all kinds of interconnect materials and coatings,the recent progress of newly developed interconnect materials were highlighted.Finally,the outlook of interconnect materials were outlined.
