摘要：

Generally metallic materials are much more machinable and have higher capacity for conducting electricity and heat than ceramics. But in a high temperature oxidizing atmosphere, metals are oxidized and lose their conductivity. The usability of heat resisting alloys as solid oxide fuel cell (SOFC) separators was evaluated, and the effects of the electrical conductive oxide coating onto the alloys on the oxidation resistance and the electrical conductivity was tested. Cr2O3-forming alloys which were coated with La0.85Sr0.15CoO3 exhibited electrical resistance as low as 5 m Omega cm(2) for 8000 h at 1273 K in air. A fuel cell with the coated alloy separator generated 0.73 V at 300 mA/cm(2).
