Abstract:

One of the pressing aims at present in the development of technologically successful energy conversion in electrochemical fuel cell systems is the finding of electrode materials on which, under given experimental conditions, the process of cathodic dissolution of oxygen can function sufficiently rapidly. The eventual objective of the study on oxygen electrodes is a reversible oxygen electrode, i.e. one which works at a sufficient rate and a negligible overpotential. The experimental program has been designed to determine the mechanism of oxygen reduction at various experimental conditions, and to find the major factors affecting the catalytic activity of the reaction. For this purpose, the 02 reaction is studied on a number of metal electrodes and on various compounds stable in acid solutions and at high electrode potentials. Author
