Corrosion-resistant metallic member, metallic separator for fuel cell comprising the same, and process for production thereof |
摘要 |
A highly corrosion-resistant material and a corrosion-resistant member which are improved in corrosion resistance, adhesion, contact electrical resistance, electrical conductivity, airtightness, etc. and are suitable for use as, e.g., a metallic separator for polymer electrolyte fuel cells (PEFC); and a process for producing them. A thin noble-metal layer is formed on the desired part of the surface of a metallic base and then subjected to compression working. The coated base may further be subjected to anticorrosive treatment with a liquid phase containing a peroxide or ozone or with an active gas atmosphere. <IMAGE> <IMAGE> <IMAGE> <IMAGE> <IMAGE> <IMAGE> |
