    摘要: A membrane electrode assembly having a temperature responsive layer whose material permeability is reduced with temperature rise, on a laminate including an anode catalyst layer, an electrolyte membrane and a cathode catalyst layer in this order, and a fuel cell using the same are provided. The temperature responsive layer may be composed of a porous layer containing a temperature responsive material whose moisture content changes at a phase transition temperature. It is possible to repress increase in fuel supply amount to the anode catalyst layer in association with temperature rise, and moisture evaporation from the electrolyte membrane in association with temperature rise, and to prevent excessive temperature rise and thermal runaway of the fuel cell.
