MANUFACTURING METHOD FOR ELECTRODE CATALYST LAYER, MANUFACTURING METHOD FOR MEMBRANE ELECTRODE ASSEMBLY, AND MANUFACTURING METHOD FOR FUEL CELL

摘要

A manufacturing method for an electrode catalyst layer includes: containing a conductive carrier on which a catalyst is supported, a substrate, an electrolyte resin and a supercritical fluid inside a closed container (S 102 to S106); and cooling the substrate to form an electrode catalyst layer, having the conductive carrier on which the catalyst is supported and the electrolyte resin, on the substrate (S 108).
