CATALYST FOR SOLID POLYMER FURL CELL, ELECTRODE FOR SOLID POLYMER FURL CELL, AND FUEL CELL |
摘要 |
The present invention has as its object the provision of a solid polymer fuel cell catalyst exhibiting high durability and high power generation performance regardless of the humidification conditions or load conditions. The present invention relates to a solid polymer type fuel cell catalyst which is comprised of a carbon material which carries a catalyst ingredient, wherein the amount of adsorption of water vapor (V 10 ) at 25°C and a relative humidity of 10% of the carbon material is 2 ml/g or less and the amount of adsorption of water vapor (V 90 ) at 25°C and a relative humidity of 90% of the carbon material is 400 ml/g or more. |
