Fuel cell separator and method of manufacturing the separator

摘要

A fuel cell separator ( 20 ) having a central part ( 22 ) and an outer peripheral part ( 30 ). The central part is a metal member made of stainless steel or the like. Multiple gas passages ( 31, 32 ) and multiple product water passages ( 33 ) are formed in the peripheral part. To ensure corrosion resistance of the gas passages and the product water passages, the peripheral part is a rubber member made of silicone rubber. A projecting central seal part ( 41 ) for surrounding the central part is formed integrally with the peripheral part.
