METHOD OF MANUFACTURING A FUEL CELL SEPARATOR

摘要

A fuel cell separator (20) having a central part (22) and an outer peripheral part (30) is disclosed. The central part consists of 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.
