<P>PROBLEM TO BE SOLVED: To provide a separator material for a fuel cell capable of strongly and uniformly forming an Au layer or a layer including Au in the surface of a titanium base material and capable of securing adhesiveness and corrosion resistance to be required for a separator for a fuel cell. <P>SOLUTION: In the separator material for the fuel cell, an alloy layer 6 made of Cr and Au or an Au single layer 8 is formed in the surface of the Ti base material 2, and an intermediate layer 2a including Ti, O and Cr and including Au of less than 20 mass% exists between the alloy layer or the Au single layer and the Ti base material. As going to lower layers from a depth of 1 nm from the outermost surface, the maximum content of C to a depth, at which Ti of 50 mass% is included, is 10 mass% or less. <P>COPYRIGHT: (C)2011,JPO&INPIT |
