Fuel cell separator and polymer electrolyte fuel cell |
摘要 |
Disclosed is a fuel cell separator molded from a fuel cell separator composition mainly containing a conductive material and a binder, characterized in that said separator is specified such that after 3.5 g of a test piece cut from said fuel cell separator is put in 305 mL of pure water and the water is heated at 90° C. for 500 hr, an electric conductivity of the water is 50 muS/cm or less. The fuel cell separator thus obtained is effective to reduce elution of ions and exhibit a high moldability and a high dimensional stability. Further, a polymer electrolyte fuel cell using the fuel cell separators is effective to exhibit a stable output without reduction in output during operation and enhance the operational efficiency.
