CA 2436701

A fuel cell separator having dense areas and porous areas is manufactured by charging powdered molding material into a compression mold, then compression molding the powdered material. The powdered material is charged respectively for the dense areas of the separator and for the porous areas of the separator, following which the respectively charged molding materials are integrally compression molded to form dense areas and porous areas. This process can be used to inexpensively mass-produce fuel cell separators in which dense areas and porous areas are selectively formed where required. The respective areas can be conferred with a uniform density or porosity even in separators having flow channels of complex shape.
