摘要： A separator for a fuel cell comprising a gold covering layer formed on the surface of stainless steel plate a method for producing a separator, in which exfoliation and fracture of the gold covering layer can be prevented and corrosion resistance and durability can be obtained, are provided. Voids are formed by intergranular corrosion treatment at a surface of the stainless steel plate, and the gold covering layer is formed so as to be embedded in the voids. Limit value of radius of curvature in bends in which exfoliations or fractures in the gold covering layer is formed can be reduced by satisfying the equation 0.2≦4/d/L≦80 wherein L(μm) is the average grain size of the surface of stainless steel plate, and d(μm) is the thickness of the gold covering layer.

摘要： A separator for fuel cells which has a gold covering layer on the surface of a metal plate and is formed by plastic working, wherein the relationship (R+D)/R≦1.025 (50 μm≦R≦1000 μm) is satisfied assuming the minimum bending radius R at a plastic worked portion is R (μm), and the thickness of the gold covering layer is D (μm). According to the separator for fuel cells, exfoliation or cracking is prevented in the gold covering layer after plastic working, whereby corrosion resistance and durability can be remarkably improved.
