Cobalt dibenzotetraazannulene (CoTAA) has been covalently linked via an acyl ligand to carbon (Vulcan XC-72). This bonded-CoTAA has been shown, in rotating disk electrode tests, to have catalytic activity equal to platinum on a weight percent basis for the oxygen dissolution reaction at room temperature in concentrated phosphoric acid. Bonded-CoTAA has been shown to be stable in 150/sup 0/C concentrated phosphoric acid. Performance of bonded-CoTAA as a cathode in a primary fuel cell will be determined in the next quarter.
