Abstract: PURPOSE: A manufacturing method of an electrode for a fuel cell is provided to continuously maintain a catalyst layer and a porous structure for operation of a fuel cell, to be able to manufacture a pore structure with various sizes and distributions, and to facilitate control of the catalyst layer and the porous structure. CONSTITUTION: A manufacturing method of a Catalyst layer-combined electrode for a polymer electrolyte membrane fuel cell comprises: a step of providing plate-like porous metal foam(2,2a,2b) or a metal aerogel having a porous structure of nanometer or micron size; a step of manufacturing a catalyst layer-integrated electrode by fixing a catalyst to the metal foam or metal aerogel. The manufacturing method additionally comprises a step of impregnating an ion-conducting material into the catalyst layer-integrated electrode.
