摘要： PROBLEM TO BE SOLVED: To provide a low-cost, highly durable, and highly anti-corrosive metal separator for solid polymer electrolyte fuel cell by forming an additive element concentrated layer on the surface of an iron based alloy containing an anti-corro sive element, oxidizing it, and forming an anti-corrosive layer. SOLUTION: This metal separator with improve anti-corrosivity is so formed that the surface of a base metal 1 composed of the iron-based alloy containing at least one kind out of chromium, nickel, titanium, niobium, aluminum and silicon is etched to form the concentration layer 2 having concentrated additive element concentration in the vicinity of the surface. The formation of the additive element concentrated layer can bring out higher anti-corrosivity than the original anti-corrosivity of the base metal with less quantity of the additive element.
