PURPOSE: A manufacturing method of a catalyst of cathode materials for fuel cell is provided to improve uniformity and adhesion of a catalyst, to not use a chemical reductant, to have simple and economic process. CONSTITUTION: A manufacturing method of a catalyst comprises: a step of adding cathode material into an acidic solution in order to modify surface of the cathode material; a step of adding the cathode material into a catalyst precursor solution; and a step of irradiating the cathode material with radiation. The acid solution comprises one or more selected from sulfuric acid, nitric acid, hydrochloric acid and acetic acid. The catalyst precursor solution comprises one or more metal salts selected from gold, silver, copper, platinum, nickel, zinc and palladium. |
