FUEL CELL SEPARATOR AND METHOD FOR MANUFACTURING FUEL CELL SEPARATOR

摘要

In a fuel cell separator, an iron-based hydrous oxide film (24) is formed on a passive film (22) of the SUS separator base material (20), which is the surface of the peripheral portion of the SUS separator base material (20), by performing cathodic electrolytic treatment in an alkaline solution to the surface of the peripheral portion of the SUS separator base material (20), excluding a gas flow channel, and furthermore, a water-soluble electrodeposited resin layer (26) is formed on the iron-based hydrous oxide film (24).
