Abstract:

Oxygen electrodes on platinum in 1 M KOH are described which exhibit rest potentials from 0.9 to 1.59 0.01 V, vs H2 1 atm in the same solution. The electrodes will operate reversibly about these rest potentials with respect to small anodic and cathodic loads. The currentpotential IE plots at higher loads are similar in slope and position for electrodes of both low and high rest potential. The effects of impurities, pH, and pressure on these potentials and IE curves are investigated experimentally. The self-sustaining nature of these potentials is demonstrated by potentialtime recovery curves on a 1.45 V electrode. The sorption of oxygen on platinum and the nature of the peroxide electrode are reviewed briefly to clarify the results obtained on the high potential electrodes. Author
