PROBLEM TO BE SOLVED: To provide a metal separator for a fuel cell, which is excellent in electrical conductivity and corrosion resistance, and to provide a method for manufacturing the same.SOLUTION: The metal separator for a fuel cell comprises a base made of a metal material and a coating formed on a surface of the base and made of a crystalline nitride. After a conductive amorphous film is formed on the surface of the base, the coating made of the crystalline nitride may be formed thereon. Since the surface of the base made of the metal material is coated with the coating made of the crystalline nitride, stable power generation performance can be achieved by securing airtightness, corrosion resistance, and electrical conductivity even when the metal separator is used on both the fuel electrode side and the air electrode side of a fuel cell. |
