Abstract
It has been shown by impedance measurements that over a large range of potentials the current at the oxygen electrode of hydrogen-oxygen ion exchange membrane fuel cells is controlled by a charge tra11sfer reaction. The frequency range used covered six decades. The influence of the hydrogen ion concentration on the rate of the electrode processes was studied by replacing part of the hydrogen ions in the membrane by sodium ions. Limiting currents proportional to the hydrogen ion content were observed.
