NOVELTY - An organic solvent is added to membrane-electrode assembly (MEA), and alloy catalyst and Nafion (RTM: sulfonated tetrafluoroethylene based fluoropolymer-copolymer) are separated by adding pure water to the MEA. The separated alloy catalyst is ultrasonically dispersed and cobalt is dissolved by adding the dispersed alloy catalyst to acid. Cobaltous hydroxide is produced by filtering the solution and adding caustic soda. Chloroplatinic acid solution is produced and further processed to obtain ammonium chloroplatinate and ammonium chloropalladate.    USE - Collection of alloy from MEA of fuel cells (claimed).    ADVANTAGE - The method enables selective separation of platinum, cobalt and palladium.    DETAILED DESCRIPTION - An organic solvent is added to membrane-electrode assembly (MEA), and alloy catalyst and Nafion (RTM: sulfonated tetrafluoroethylene based fluoropolymer-copolymer) are separated by adding pure water to the MEA added with solvent. The separated alloy catalyst is ultrasonically dispersed and cobalt is dissolved by adding the dispersed alloy catalyst to acid. Cobaltous hydroxide is produced by filtering the solution in which cobalt is dissolved and adding caustic soda and collecting it. Chloroplatinic acid solution is produced by adding and dissolving the alloy catalyst from which cobalt is removed in aqua regia. Nitric acid is removed by adding and concentrating hydrochloric acid to the chloroplatinic acid solution. Ammonium chloroplatinate is produced by adding ammonium chloride saturated solution to the solution from which nitric acid is removed. Platinum is collected by filtering and separating the solution including ammonium chloroplatinate and collecting platinum by plasticizing ammonium chloroplatinate. Impurities are precipitated from the solution separated from ammonium chloroplatinate by using ammonia. Ammonium chloropalladate is produced from the solution remaining after removing the precipitated impurities by using hydrochloric acid and filtering it. Palladium is collected by plasticizing the filtered ammonium chloropalladate ammonium.
