Abstract

In this paper, preliminary data of methanol and ethanol anodic oxidation on Y0.5Ca0.5BaCo4O7 perovskite electrode in aqueous alkaline solution (1 M KOH) are presented. Electrocatalytic activity of methanol and ethanol anodic oxidation becomes a serious issue, especially due to the utilization of 114 layered cobalt perovskite electrodes in fuel cells. In order to elucidate the mechanism of methanol (MOR) and ethanol oxidation reactions (EOR) which occur at this perovskite electrodes interface, advanced studies are required. Electrochemical behavior has been studied by cyclic voltammetry, chronoamperometry and chronopotentiometry. Obtained results have shown that Y0.5Ca0.5BaCo4O7 perovskite electrodes are suitable as anodes in fuel cells.
