NOVELTY - Metal-based (M/N-C) catalyst is prepared by adding at least one salt precursor of transition metal iron, cobalt or nickel to glycol solution of sodium hydroxide; stirring for 0.5-3 hours at 25-180 degrees C; adding polypyrrole (PPy) until mass of transition metal is 0.1-30% of total mass of transition metal and PPy; adding 10-40 times volume of water; depositing for 1-24 hours at 25-60 degrees C while stirring; filtering; washing and drying mixture; and heat treating dried sample for 1-3 hours at 500-900 degrees C to obtain target product M/N-C catalyst (where M is at least one of iron, cobalt, or nickel).    USE - Metal-based (M/N-C) catalyst used as oxygen reduction catalyst for proton exchange membrane fuel cathode cell (claimed).    ADVANTAGE - The metal-based (M/N-C) catalyst has improved catalytic activity.    DETAILED DESCRIPTION - Metal-based (M/N-C) catalyst is prepared by adding pyrrole monomer in water solution of surfactant and/or glycol, in which concentration of surfactant is not less than critical micelle concentration and concentration of pyrrole monomer is 0.1-2 mol/l; stirring for 0.5-2 hours at 0-25 degrees C; adding oxidizer; stirring for 0.5-2 hours at 0-25 degrees C to process polymerization of pyrrole monomer and generate polypyrrole (PPy), in which mole ratio of oxidizer to pyrrole monomer is 0.5:(1-10); soaking combined PPy to 50-100 mass% carbinol solution to remove residual surfactant and oxidizer; filtering; washing and drying; adding at least one salt precursor of transition metal iron, cobalt or nickel to glycol solution of sodium hydroxide, in which concentration of transition metal is 0.0001-0.05 mol/l and that of sodium hydroxide is 1-2 mol/l; stirring for 0.5-3 hours at 25-180 degrees C; adding PPy until mass of transition metal is 0.1-30% of total mass of transition metal and PPy; adding 10-40 times volume of water; depositing for 1-24 hours at 25-60 degrees C while stirring; filtering; washing and drying mixture; and heat treating dried sample for 1-3 hours at 500-900 degrees C to obtain target product M/N-C catalyst (where M is at least one of iron, cobalt, or nickel). An INDEPENDENT CLAIM is included for preparation of metal-based (M/N-C) catalyst.
