Abstract
Oxygen reduction was studied at a platinum electrode on a new ceramic membrane named ‘Celec’ in 6m KOH with a view to application of this ceramic material in Zn/air batteries. Cyclic voltammetry and impedance measurements were carried out on the oxygen electrode to investigate the oxygen reduction mechanism in the presence of the ‘Celec’ ceramic. The impedance diagrams recorded at low and high overpotentials show different characteristics, which are well interpreted by the proposed mechanisms.
