By considering published data on the kinetics of the oxygen electrode at a platinum surface it is suggested that the electrode process follows the same path in both acid and alkaline solution. This path is identified, and attention is drawn to certain restrictions on the use of diagnostic criteria.
R6snme---Sur la base des dorm&es publiees concernant la cinetique de l'electrode a oxygene sur surface de platine on suggere que le processus d'electrode suit le meme chemin en solution acide et en solution alcalime. On identitie ce chemin et on attire l'attention sur certaines restrictions qu'il convient d'imposer a l'usage des criteres diagnostiques.

The electrochemical reduction of dissolved oxygen at pre-oxidized and pre~reduced metal electrodes has been studied using the galvanostatic and chronopotentiometric methods. Oxygen reduction at pre-oxidized electrodes occurs by a pH-dependent mechanism that gives water as the reduction product. With
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
The anodic evolution of oxygen was investigated on the platinum oxide electrode, prepared by a thermal decomposition method, in alkaline solutions; the overvoltage data were reproducible on this electrode. On the basis of reliable mechanistic observations, the most probable path under Langmuir condi
