An exptimental program was conducted ta determine the catalytic activity of platinum supported on carbon for the electrochemical reduction of oxygen in phosphoric acid as a function of temperature and electrolyte concentration. The Tafel slope was found to be approximately equal to 2.3 RT/F and inde
The steady-state reduction ofoxygen in O,-saturated 2 N H,SO, solution was obtalned at constant current on the front side of a Pt fo11 diaphragm before and after strong anodization of the back side. Strong anodization converts the Pt to a Pt-0 alloy. In all cases, the overvoltage for O2 reduction wa
