ABSTRACT:
A catalyst material of carbon black powder having nitrogen affixed to its surface and process for its production by contacting carbon black powder particles with a plasma or low energy beam of nitrogen containing ions affixing the nitrogen ions to the surface of the particles in a concentration of about 0.1 to about 10 percent, based upon the total number of surface atoms. The catalysts are particularly suited for use in phosphoric acid fuel cells.
