PURPOSE: A producing method of a high rate platinum-supported catalyst for a fuel cell is provided to improve the yield of platinum by using a crystalline type of carbon carrier. CONSTITUTION: A producing method of a high rate platinum-supported catalyst for a fuel cell comprises the following steps: mixing ethylene glycol with NaOH, a platinum precursor, and carbon; reducing the platinum precursor by oxidizing the ethylene glycol, by refluxing the mixed solution in 140~180deg C; controlling the pH for carrying platinum, by inducing the mutual attraction between the platinum and a carrier; adding and additive for improving the carrying yield of the platinum; and removing unnecessary organic compounds by heat processing and washing after collecting the catalyst. |
