Abstract: The present invention relates to a catalyst layer for a fuel cell, a method for producing the catalyst layer, and a membrane-electrode assembly and a fuel cell including the catalyst layer. More particularly, the invention relates to a catalyst layer for a fuel cell, the catalyst layer including a catalyst, a heat dissipation material, and an ionomer and having an effect that the heat generated by an exothermic reaction in the catalyst layer can be efficiently discharged to the outside and a phenomenon of deterioration of a membrane-electrode assembly caused by temperature increase in the catalyst layer can be suppressed; a method for producing the catalyst layer; and a membrane-electrode assembly and a fuel cell, both including the catalyst layer.

Abstract: Provided is a membrane-electrode assembly having improved binding strength between a polymer electrolyte membrane and a catalyst layer and improved durability of the catalyst layer. An embodiment of the present invention provides a membrane-electrode assembly including a polymer electrolyte membrane and a catalyst layer disposed on at least one surface of the polymer electrolyte membrane, wherein the catalyst layer contains a first composite and a second composite; the first composite contains a first catalyst containing a support and first metal particles supported on the support, and a first ionomer coated on the surface of the first catalyst; the second composite contains a second catalyst that contains second metal particles and is not supported on a support, and a second ionomer that is not coated on the surface of the second catalyst; and the first ionomer and the second ionomer are identical with or different from each other.
