TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preparation (Claimed): Preparation of fuel cell catalyst comprises: (a) dissolving the soluble copper salt into ethylene glycol liquid to make the concentration of the copper ions (CU2+) to 0.01-0.1 mol/l in the solution, adding citric acid, citrate or its salts to the soluble copper salt in a molar ratio of 1-3:1, adding an aqueous solution of palladium salt with the carbon carrier and then finally mixing to obtain a mixed solution having a mass ratio of copper salt, palladium salt and carbon carrier of 7-9:1:1; (b) adjusting the pH value of the mixed solution to 9-10 by adding the potassium hydroxide to ethylene glycol solution containing the mixed solution, heating the solution and then reducing the temperature of the solution from 160-190 degrees C, reacting the mixture for 2-6 hours thus maintaining a constant pH value of the reacted mixture, washing the reaction solution until the reaction mixture becomes neutral, and centrifugally drying the mixture to obtain palladium copper molybdenum alloy particles; and (c) uniformly dispersing the palladium copper molybdenum alloy particles into ethylene glycol mixed solution and then adding chloroplatinic acid to the obtained mixture, in which the mass ratio of palladium copper molybdenum alloy particles and the ethylene glycol mixed solution is 1.5-3:1, adjusting the pH of the final solution to 7-9 and maintaining the temperature of the final solution at 80-100 degrees C by heating, reacting the mixture for 2-6 hours, washing the final solution until the solution becomes neutral without the chloride ion and then drying the final solution to obtain the catalyst. Preferred Method: The drying step is carried out at temperature of 50-80 degrees C for 20-30 hours. The catalyst is placed in a dilute nitric solution at room temperature for 3 hours, where the concentration of nitric acid solution is 1-2 mol/l. Preferred Components: The carrier is Vulcan XC-72 (RTM: Carbon black) type. The soluble copper salt is copper sulfate pentahydrate, copper chloride and/or copper nitrate. The soluble palladium salt is palladium chloride or palladium acetate. The concentration of soluble palladium salt is 1 mol/l.
