Abstract:

This paper investigates anodic oxidation of methanol on a calcium doped cobalt layered perovskite type 114 electrode in aqueous alkaline solution (1M KOH). Electrocatalytic activity formethanol anodic oxidation becomes a serious issue, especially due to the utilization of layered cobalt perovskite electrodes in fuel cells. In order to understand the oxidation mechanism on the surface of these type of electrodes, comprehensive researches were necessary. Electrochemical behavior has been studied by cyclic voltammetry and linear polarization.
