The thus formed separator (10) has an Au plating film (12) o n a major surface (10a) and a cut face (16), which is an edge face (16) continuous with the major surface (10a). A part of the metal base (13) is exposed from a part of the cut face (16). The width of the exposed part is 1 mm or less. In such a way, a metal member for fuel cells having a sufficient corrosion resistance and producible readily at low cost, its manufacturing method, and a fuel cell having such a metal member for fuel cells are provid ed.

摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a corrosion resistant metallic member which has a high degree of a corrosion resistance and is particularly useful as a separator for fuel cells and to provide a corrosion resistant metallic member. SOLUTION: When thin noble metal layers 21b and 31b are formed on both surfaces of a metallic base material and are molded to peak and valley shapes by compression working, pinholes generated in forming the thin-film layers remain as 42a, 45a, 51a, 54a, etc., and the metallic base material is exposed in these segments. These exposed sections are treated by a liquid phase system containing a peroxide or ozone in order to prevent the corrosion thereof. Oxides 61, 62, 71 and 72 are formed by this treatment, by which the thin-film layers are restored.
