NOVELTY - Palladium intercalated montmorillonite catalyst and carbon powder are mixed in mass ratio of 1:0.5-2, palladium intercalated montmorillonite catalyst is dispersed in absolute ethyl alcohol, ultrasonically oscillated for 10-50 minutes, stirred for 30-70 minutes, to form palladium intercalated montmorillonite catalyst suspension (0.01-0.1 g/ml). Carbon powder is added to the suspension, ultrasonically oscillated for 1-4 hours, filtered in vacuum, washed with deionized water, dried and ground, to obtain palladium intercalated montmorillonite catalyst.    USE - Manufacture of palladium intercalated montmorillonite catalyst used for cathode for fuel cell.    ADVANTAGE - The palladium intercalated montmorillonite catalyst is manufactured efficiently and economically with excellent stability, and high redox activity.    DETAILED DESCRIPTION - Sodium montmorillonite and hexadecyl trimethyl ammonium bromide are mixed in mass ratio of 1:0.5, sodium montmorillonite is dissolved into deionized water at 60 degrees C, and ultrasonically stirred for 30 minutes, to form sodium montmorillonite suspension. Hexadecyl trimethyl ammonium bromide and sodium montmorillonite suspension are ultrasonically stirred at 60 degrees C for 20 minutes, heated at 100 degrees C for 24 hours, cooled to 60 degrees C, filtered, washed with deionized water, dried and ground, to obtain organic cation modified montmorillonite. The organic cation modified montmorillonite is dissolved in ethylene glycol, ethanol or isopentyl diol, ultrasonically oscillated for 40 minutes, stirred at 50-70 degrees C for 1-5 hours, perfluorinated sulfonic resin solution is added to the suspension, stirred at 50-70 degrees C for 5-24 hours, and cooled to room temperature, to obtain perfluorinated sulfonic resin intercalated organic cation modified montmorillonite suspension. Palladium chloride or palladium dichloride solution into perfluorinated sulfonic resin intercalated organic cation modified montmorillonite suspension, stirred at normal temperature for 5-24 hours, pH is adjusted to 2-6, maintained at 60-120 degrees C, stirred for 3-8 hours, cooled to room temperature, filtered in vacuum, washed using deionized water, dried and ground, to obtain palladium intercalated montmorillonite catalyst. Palladium intercalated montmorillonite catalyst and carbon powder are mixed in mass ratio of 1:0.5-2, palladium intercalated montmorillonite catalyst is dispersed in absolute ethyl alcohol, ultrasonically oscillated for 10-50 minutes, stirred for 30-70 minutes, to form palladium intercalated montmorillonite catalyst suspension (0.01-0.1 g/ml). Carbon powder is added to the suspension, ultrasonically oscillated for 1-4 hours, filtered in vacuum, washed with deionized water, dried and ground, to obtain palladium intercalated montmorillonite fuel battery cathodic catalyst. The mass ratio of montmorillonite and palladium chloride or palladium dichloride is 1:0.1-0.8. The mass of palladium chloride or palladium dichloride is 0.01-0.1 mol/L. The mass ratio of organic cation modified montmorillonite and perfluorinated sulfonic resin is 1:0.1-0.3. The concentration of perfluorinated sulfonic resin solution is 5 %mass.
