METHOD FOR PREPARING ALLOY CATALYST AND METHOD FOR MANUFACTURING SOLID HIGH-POLYMER TYPE FUEL BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a method for preparing an alloy catalyst containing active metals which have a high alloying degree and are more pulverized. SOLUTION: This method includes a state for preparing an alloy colloid solution by adding >=2 kinds of metal salts to an aqueous solution in which a reducing agent consisting of an organic acid is dissolved at the same period in the state of dissolving the metal salts in water and a stage for depositing the alloy colloid particles in the solution on a carrier.
