FUEL CELL SEPARATOR AND PRODUCTION METHOD FOR FUEL CELL SEPARATOR

摘要

A separator (12) includes a gas flow path forming body (16), which includes a substrate (18) made of stainless steel, a resin layer (20) arranged on the substrate (18), and a conductive layer (24) arranged on the surface of the resin layer (20). The resin layer (20) contains a filler (22), which has conductivity and greater hardness than an oxide film (18b) of the substrate (18). The conductive layer (24) contains graphite (26). The filler (22) extends through the oxide film (18b) of the substrate (18) and contacts the base material (18a).
