Title:
METHOD FOR PRODUCING FUEL CELL SEPARATOR, AND FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2011/092885
Kind Code:
A1
Abstract:
Disclosed is a method for producing a fuel cell separator that is suppressed in release of metal ions therefrom, thereby being capable of suppressing decrease in the proton conductivity of the electrolyte and decomposition of the electrolyte due to the release of metal ions from the fuel cell separator.
Specifically disclosed is a method for producing a fuel cell separator, which comprises a step wherein a molding composition is prepared by blending staring material components containing graphite particles and a resin component, and then the molding composition is molded. Before molding the molding composition, the metal component is removed from the molding composition. By removing the metal component from the entirety of the molding composition, the amount of metal components contained in a fuel cell separator can be reduced.
