METHOD OF PREPARING ELECTROCATALYSTS FOR FUEL CELLS AND ELECTROCATALYSTS THEREOF

摘要

A method of manufacturing electrocatalysts for fuel cells, and the electrocatalysts manufactured thereby are provided to prevent separation of catalyst and a supporter generated in an electrode and to improve performance of the lectrocatalysts. A method of manufacturing electrocatalysts for fuel cells comprises the following steps of: synthesizing a spherical polymer(S11); adding the synthesizing polymer in a mixed solution(S12); forming a spherical titanium dioxide support by mixing a Ti(SO4)2 solution in a polymer-added mixed solution(S13); and forming the electrocatalysts by dipping a platinum catalyst in titanium dioxide supporter(S14).
