The influence of hydrogen partial pressure, current density, and temperature on the anodic oxidation of sorbed H and the anodic generation of sorbed O were determined. Electrode processes were evaluated and separated to give the following quantities a the amount of H associated with a Pt surface and its immediate vicinity, b the extent to reaction of H atoms, absorbed in the metal interior, that migrate to the surface of the metal and are either ionized or react with O atoms, c the extent of reaction of H2 from the solution phase, d the amount of O adsorbed on the Pt surface, and e the amount of O absorbed in the Pt surface layers skin. The kinetics of the open-circuit reaction of galvanostatically determined amounts of sorbed O with H2 were also determined.
