METHOD OF PREPARING PLATINUM ALLOY CATALYST FOR FUEL CELL ELECTRODE

摘要

A method of preparing a platinum alloy catalyst for a fuel cell electrode includes: (a) adding a carbon material, a platinum precursor, and a transition metal precursor to ethanol and dispersing the mixture; (b) adding sodium acetate powder or an ammonia solution containing ethanol as a solvent to the solution obtained in step (a) and stirring the resulting solution; (c) adding sodium borohydride to the solution obtained in step (b) and reducing the metal ions of the platinum precursor and the transition metal precursor; and (d) obtaining a platinum alloy catalyst in the form of powder through washing and drying processes. This method can reduce the amount of platinum to be used for manufacturing a fuel cell electrode and thereby reduce the manufacturing cost.
