摘　　要：综述了LaCrO3材料在固体氧化物燃料电池(SOFC)中作为陶瓷连接材料、合金连接体的涂层材料以及新型阳极材料的国内外最新研究进展。介绍了LaCrO3作为陶瓷连接材料的使用要求,在热膨胀性能、烧结性能、电性能和化学稳定性能等方面的研究情况,并介绍了磁控溅射、等离子喷涂、溶胶-凝胶(Sol-gel)工艺等几种LaCrO3涂层材料制备方法以及LaCrO3作为新型阳极材料的催化性能、导电性能和热膨胀性能等方面的研究进展,对其发展前景进行了展望。The recent research progresses in LaCrO3 used as ceramic interconnect, alloy interconnect coating and new anode material for solid oxide fuel cells （SOFCs）are reviewed. The conventional doped LaCrO3 interconnect is discussed from the requirements, sinterability, conductivity, thermal expansion and chemical stability properties. The advent of anode-supported planar SOFC allows lower operation temperatures and LaCrO3 can be applied as the protective coating of alloy interconnect. Some coating preparation methods are introduced, including magnetron sputtering, plasma spraying and sol-gel progress. The developments of new LaCrO3 anode materials are also presented from their catalytic performance, conductivity and thermal expansion properties. Furthermore, brief development directions of each use of LaCrO3 are proposed.
