TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Process: In the process, the carbon precursor material is refluxed within a solution of nitric acid in order to oxidize the carbon precursor material. The nitrogen functional group is added into the oxidized carbon precursor material via a polymerization process of a nitrogen precursor donor followed by pyrolysis. The process further involves removing impurities from the carbon precursor material. The carbon precursor material is substantially free of metal after the impurities are removed. The impurities are removed by dissolving them in an acidic solution comprising hydrochloric acid or sulfuric acid. The metal-nitrogen chelate has a structure with the formula MN4, (in which M is a metal and N is a nitrogen atom chelated with M, though the nitrogen is bonded to another molecule). The metal-nitrogen chelate is deposited onto the electrode support via a reflux process followed by pyrolysis. The support deposited with metal-nitrogen chelate is utilized as a fuel cell cathode. Preferred Components: The carbon precursor material comprises carbon black. The pyrolysis takes place at greater than or equal to 500 degrees C. The support deposited with metal-nitrogen chelate further comprises a platinum catalyst ( less than or equal to 0.01 mg cm-2). The support deposited with metal-nitrogen chelate further comprises a cobalt catalyst.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The oxygen functional group comprises quinone, carboxyl, lactone, phenol, carbonyl, ether, pyrone and/or chromene. The nitrogen precursor comprises melamine, urea, thio-urea and/or selenourea. EXAMPLE - Ketjen Black EC 300J (RTM: Carbon black) was treated with HNO3 solution (9.8 M) at 80 degrees C for 7 hours under refluxing conditions, in order to introduce oxygen functional groups onto the carbon surface. The oxidized carbon specimen was rinsed with de-ionized water, followed by drying under vacuum at 80 degrees C. A cobalt-nitrogen chelate complex (CoNx) was deposited onto the oxidized carbon using cobalt nitrate (98%) and ethylene diamine as Co- and N-precursors, respectively. A desired amount of ethylene diamine was added slowly into cobalt nitrate solution (0.015 M) in ethanol, followed by the addition of the oxidized carbon powder under stirring conditions. The molar Co:N ratio in the reaction mixture was maintained at 1:16. The reaction mixture was refluxed at 85 degrees C for 4 hours, followed by drying under vacuum at 80 degrees C. The resulting Co-deposited carbon was subjected to heat-treatment in an argon atmosphere at 700 degrees C and at 8.8 MPa for 3 hours. The heat-treated Co/C sample was treated with sulfuric acid (0.5 M) at 25 degrees C for 2 hours to remove excess Co on the carbon surface. Chloroplatinic acid (H2PtCl6) (4 mM) and hydrochloric acid solutions (0.27 M) were mixed with de-ionized water containing the Co/C support. Sodium formate solution (2 M) was added slowly to the reaction mixture, followed by refluxing at 80 degrees C for 20 hours. The resulting platinum-cobalt on carbon (Pt-Co/C) sample was rinsed with de-ionized water, and then was dried under vacuum at 80 degrees C for 12 hours to obtain Pt-Co/C catalyst.
