Conductive amorphous carbon was coated on the stainless steel separators by using electron cyclotron resonance (ECR) plasma sputtering technique. The carbon-coating reduced contact resistance between carbon paper and stainless steel substrate by two orders of magnitude. The carbon-coating also enhanced corrosion resistance of the stainless steels. Polarization performances of the polymer electrolyte fuel Cell (PEFC) using the carbon-coated SUS316L and SUS329J4L separators were comparable with that using the conventional carbon separator.
