ELECTROLYTE MEMBRANE AND SOLID POLYMER FUEL CELL

摘要

The electrolyte membrane for a solid polymer fuel cell is a laminated body of; (1) a first layer (11) composed of an ion exchange resin, and (2) a second layer (12) composed of a porous body and an ion exchange resin applied in the fine pores of the porous body. The electrolyte membrane is characterized in that the ion exchange capacity of the ion exchange resin of the second layer (12) is larger than the ion exchange capacity of the ion exchange resin of the first layer (11). Thus, both the output performance and durability can be provided at a high level.
