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.
