Dioxygen reduction has been examined in several new acid electrolytes and mixtures of these electrolytes with concentrated phosphoric acid used in present acid H2-O2 fuel cells. The polarization curves have been determined on smooth platinum with the rotating disk and ring-disk electrodes and on high-area platinum with gas-fed electrodes of the semi-hydrophobic-type. The polarization is less than with concentrated H3PO4 in some of these alternative electrolytes. Possible explanations are discussed....
