PROBLEM TO BE SOLVED: To provide a metal separator for a fuel cell, which has a low contact resistance, excellent water repellency, and good anti-corrosiveness. SOLUTION: A fuel cell module is equipped with positive and a negative electrodes and electrolyte interposed between them, wherein a metal separator 1 is installed on each side of the module and is furnished with a groove 3 for gas flowing, and the surface of this groove at least is lined with a noble metal composite plating film consisting of entectoid of fluoro-resin or graphite fluoride particles. These separators 1 for fuel cell may be used in the same manner as a conventional separator, in particular favorably used in a fuel cell with a solid highpolymer electrolyte, and have low contact resistance, excellent water repellency at the groove 3, and good gas flowing possibility, and further an excellent anti-corrosiveness owing to the noble metal as matrix. |
