METHOD FOR PREPARING MODIFIED CATALYSTS FOR CATHODIC OXIDATION OF POLYMER ELECTROLYTE MEMBRANE FUEL CELLS AND DIRECT ALCOHOL FUEL CELLS

摘要

PURPOSE: A manufacturing method of a catalyst is provided to easily use and transport the catalyst by using solid nitration-carbonized hydrogen, and to economically manufacture the catalyst. CONSTITUTION: A manufacturing method of a catalyst for oxidizing a positive electrode of a direct alcohol fuel cell or a polymer electrolyte fuel cell, comprises the following steps: mixing a transition metal precursor and a solvent; reducing the mixed solution, and oxidizing the outcome to form a transition metal oxide catalyst; and mixing the transition metal oxide catalyst with solid hydrocarbon nitride, and heat processing the mixture.
