The use of ion implantation of carbon support materials was investigated in an effort to develop low-cost, high-activity oxygen reduction catalysts for long-life phosphoric acid fuel cells. High-energy implants into formed coatings were used to determine the catalytic action of different compounds. Low-energy implants were used to treat the surface of the entire volume of carbon black used in electrodes. Nitrogen implant support materials were more corrosion resistant and showed higher activity after addition of Pt than untreated carbon powders. Catalytic activity without addition of Pt was found implanted in blacks.
