The electroreduction of air on a platinum electrode has been investigated in trifluoromethanesulfonic acid monohydrate as part of a study involving the hydrocarbon-air fuel cell. At 135/sup 0/C, the open-circuit potential of the air electrode was 1.135V (vs. the dynamic hydrogen electrode) and the limiting current density was higher than that observed in phosphoric acid under the same conditions. Current density-potential diagrams were constructed over the temperature range of 95/sup 0/--135/sup 0/C. The activation energy for the process is low; 1500--4000 cal mole/sup -1/.
