Abstract

The structure and electrochemical activity of carbon supported Pt-free cathode catalysts (Ag/C, Mn3O4/C and AgMnO2/C) are investigated by means of transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD) and cyclic voltammetry (CV). The catalysts display ethanol-tolerance for the oxygen reduction reaction (ORR) in 0.1 M KOH electrolyte containing ethanol at different temperatures. Because crossover of ethanol from anode to cathode through the membrane can occur in alkaline direct ethanol fuel cells (ADEFCs), selectivity of the cathode catalyst is of high importance. AgMnO2/C catalyst exhibits the highest catalytic activity toward ORR in presence of alkaline electrolytes containing ethanol.
