THE formation of hydrogen peroxide is considered by some authors1–3 as the possible source of the poor efficiency of oxygen electrodes in a fuel cell. Indeed, the reduction : would proceed at a normal potential below 1.23 V if the foregoing reaction occurs in two steps: assuming that the second step is irreversible.
