    • An electrical interconnect device for a planar fuel cell, comprising solid oxide electrolyte (44), an anode and a cathode (42), is described. The interconnect device comprises a plate-like chromium-containing substrate (22) having gas-flow channels (28) on the cathode-side and a coating on the cathode-side. The coating comprises an oxide surface layer comprising at least one metal M selected from Mn, Fe, Co and Ni, and an M, Cr spinel layer intermediate the substrate and the oxide surface layer. The intermediate spinel layer is formed by reaction of M oxide with surface chromium oxide on the substrate. The coating material may be applied as oxide or as salt or metal, or a mixture, and then converted to oxide. The M-metal(s) may be mixed with non-M metal or be doped. Methods of application are described in which the oxide surface layer is partially reacted to form the intermediate spinel layer.
    • 描述了一种用于平面燃料电池的电互连装置,其包括固体氧化物电解质(44),阳极和阴极(42)。 互连装置包括在阴极侧具有气流通道(28)的板状含铬基底(22)和阴极侧的涂层。 涂层包括氧化物表面层,其包含选自Mn,Fe,Co和Ni中的至少一种金属M,以及在衬底和氧化物表面层之间的M,Cr尖晶石层。 中间尖晶石层通过M氧化物与基底上的表面氧化铬的反应形成。 涂料可以作为氧化物或盐或金属或混合物施用,然后转化为氧化物。 M金属可以与非M金属混合或掺杂。 描述了其中氧化物表面层部分地反应以形成中间尖晶石层的应用方法。
