Abstract

[PROBLEMS] To provide a fuel cell separator material which permits the formation of a strong and uniform Au layer or Au-containing layer on the surface of a titanium substrate and which can secure the corrosion resistance requisite to fuel cell separators. [MEANS FOR SOLVING PROBLEMS] A fuel cell separator material comprising a Ti substrate (2) and an alloy layer (6) formed on the surface of the substrate (2) which consists of both Au and the first component consisting of at least one noble metal that is selected from the group consisting of Ru, Rh, Pd, Ir, Os and Pt and that can be oxidized more easily than Au, wherein an interlayer which contains Ti, O, and the above first component and which has an Au content of less than 20% by mass is present between the alloy layer and the Ti substrate and a region of 1nm or above in thickness which spreads from the outermost surface toward the underlayer and which has an Au content of 50% by mass or above is present in the alloy layer or Au simple layer.
