PURPOSE: A method for manufacturing a platinum alloy catalyst for a fuel cell, an electrode for a fuel cell using the same, and a fuel cell comprising the same are provided to improve an electrochemical efficiency of a platinum alloy catalyst with reducing the content of platinum. CONSTITUTION: A method for manufacturing a platinum alloy catalyst comprises the steps of: preparing a transition metal precursor solution by mixing a transition metal precursor with a first solvent; preparing a carbon-based catalyst support solution by dispersing a carbon-based catalyst support into polyol; preparing a first mixed solution by mixing the transition metal precursor mixed solution and the carbon-based catalyst support solution, and reducing, heating, and stirring the mixture; preparing a platinum precursor solution by mixing the platinum precursor with a second solvent and reducing the mixture; preparing a second mixed solution by mixing the first mixed solution with the platinum precursor solution, and heating and stirring the mixture; and drying the second mixed solution. |
