METHOD OF MANUFACTURING FUEL BATTERY SEPARATOR

摘要

A method of manufacturing a fuel battery separator which does not increase the electrical conductivity of the coolant thereby to reduce the contact resistance. The fuel battery separator (20) separates gases in adjacent fuel battery cells. The method comprises a separator body formation step of forming a separator body (22) having a corrugated shape of a metallic material such as a titanium material or stainless steel and a conductive layer formation step of forming conductive layers (24) of a conductor, such as gold (Au), only on the surfaces of the projecting portiuons of the separator body (22).
