US 2018/0026274 A1 · METHOD FOR MANUFACTURING ELECTRODE FOR FUEL CELL AND ELECTRODE MANUFACTURED THEREBY

Abstract

A method for manufacturing an electrode for a fuel cell includes a mixing step of producing a first mixed solution by mixing a carbon support, a metal catalyst, a binder and a first dispersion solvent, a drying step of producing a first mixed solution dried body by drying the first mixed solution, a heat treatment step of heating the first mixed solution dried body, a second mixed solution production step of producing a second mixed solution by dissolving the heat-treated first mixed solution dried body in a second dispersion solvent, and a release paper coating step of producing an electrode by coating the second mixed solution onto a release paper, and then drying the second mixed solution.
