1. A method of preparing a fuel cell electro-catalyst composition, said method comprising:

  • (a) preparing a proton- and electron-conducting polymer having an electronic conductivity no less than 10

    3
    S/cm and a proton conductivity no less than 10

    4
    S/cm;

    (b) mixing and reacting said conducting polymer with a plurality of transition metal coordination complexes to produce said electro-catalyst composition having at least one heteroatom per backbone monomer unit thereof and a plurality of neutral transition metal atoms covalently bonded to at least a portion of said heteroatoms.
