SEPARATOR FOR LOW TEMPERATURE TYPE FUEL CELL AND METHOD OF PRODUCTION THEREOF |
摘要 |
A separator for a low-temperature fuel cell comprises a stainless steel substrate S having a surface to which carbonaceous particles such as graphite particles GP or carbon black aggregates CA adhere with dotted distribution. The carbonaceous particles are preferably bonded through a diffusion layer DL to the surface of the substrate S. The carbonaceous particle-dispersed layer may be a plating layer in which graphite particles GP or carbon black aggregates CA are dispersed or formed by thermal decomposition of organic components in a carbonaceous particle-dispersed paint applied to the surface of the substrate S. Since carbonaceous particles free from oxide films adhere to the surface of the acid-resistant stainless steel substrate S, contact resistance of the separator is sufficiently low. Consequently, a power generator having a plurality of fuel cells laminated together exhibits high power-generating efficiency with less heat loss caused by a Joule heat. <IMAGE> <IMAGE> <IMAGE> <IMAGE> |
