Abstract
Ag/C, Mn3O4/C and AgMnO2/C electrocatalysts were selected for nanocatalyst structure and electrochemical activity characterisation by transmission electron microscopy (TEM), X-ray spectroscopy (EDX), cyclic voltammetry (CV), X-ray diffraction (XRD) and oxygen reduction reaction (ORR). The nanocatalysts displayed ethanol-tolerance for ORR in KOH solution electrolyte at different temperatures. All electrocatalysts prevented oxidation from ethanol crossover through the membrane from the anode to cathode compartments in alkaline direct ethanol fuel cells (ADEFCs). ORR results confirmed that AgMnO2/C significantly improved the current activity.
