Fuel cell separator for solid polymer electrolyte fuel cell for electric vehicle, comprises metallic substrate having oxide film forming one surface produced by oxidation of material of substrate, and electrically conducting thin film

摘要

A fuel cell separator (10) comprises a metallic substrate (11) having an oxide film (11a) forming one surface produced by oxidation of the material of the substrate, and an electrically conducting thin film (12) formed on the surface of the oxide film of the substrate. An Independent claim is also included for the production of a fuel cell.
