ELECTROCHEMISTRY OF FUEL CELL ELECTRODES. TEMPERATURE DEPENDENCE OF HYDROGEN OVERVOLTAGE ON INDIUM AMALGAMS.

Abstract

Hydrogen overvoltage has been measured at temperatures from 14 C to 66 C using dropping amalgam electrodes containing 10.0, 20.0, 40.0, and 63.0 mole % indium. The enthalpy of activation was extrapolated to the reversible potential, and corrected for the effect of the diffuse double layer. For the most concentrated amalgams, it is approximately 1 kcal/mole lower than for mercury. This change is consistent with the decrease in overvoltage with increasing indium content at constant temperature. (Author)
