That is, when depositing metal in complex ions on the fuel cell separator by an electrodeposition process, the metal is adhered not only to a power generation region but also to a portion where the surface (separator base material surface) is exposed by the defects of the resin coat, thereby forming the metal coat on the defects. Thus, it is possible to improve the corrosion resistance of the fuel cell separator as compared to the case that the surface of the separator base material is exposed at the portions of the defects of the resin coat. | 10-28-2010 |
