Abstract
Oxygen reduction in molten NaOH at 623 K has been studied by the use of an Ni rotating disk electrode and a porous O2 gas electrode. It was clarified that the diffusing species to the electrode surface is molecular oxygen itself, and not an oxygen-containing anion, such as O2- 2, by limiting current measurements. Kinetic studies show that the following reaction mechanism is more probable: {A figure is presented} where the latter is rate determining. Since H2O transport to the electrode surface is rate determining, pO2- control is especially important, taking into account the following equilibrium; {A figure is presented}.
