<P>PROBLEM TO BE SOLVED: To provide a solid oxide type fuel cell separator material which excels in an electrical conductivity at 600°C or more and steam oxidation resistance, and in which a Cr evaporation is also suppressed. <P>SOLUTION: The solid oxide type fuel cell separator material is a separator material in which a TiN coating layer having a thickness of 0.05-100 μm is formed to a ferrite stainless steel of 11-40 mass% of Cr, and a Ti concentration of the TiN coating layer is adjusted to more than 40 atom%. The ferrite stainless steel contains C: below 0.1 mass%, N: below 0.1 mass%, Si: below 1.5 mass%, Mn: below 1.5 mass%, P: below 0.10 mass%, and S: below 0.01 mass%, in addition to the Cr. <P>COPYRIGHT: (C)2007,JPO&INPIT |
