Date Sep. 17, 1981.Disclosed is a method of manufacturing a catalyst composed of fine metal particles having a large specific surface area, such as a platinum black catalyst. According to this method, a solution containing a platinum ion and at least one metal ion or complex ion having an oxidation-reduction potential different from that of platinum is reduced, and the metal having an oxidation-reduction potential different from that of platinum is dissolved out from the precipitated particles. The catalyst obtained according to this method has a very fine particle size and is suitable for an electrode of a fuel cell. |
