Two new electrodes were prepared and characterized electrochemically; Zn/NP/Iron and Cu/NP/Iron, for a direct methanol fuel cell (DMFC). Themorphology and structure of the catalyst layer were analyzed by optical microscopy. The catalyst coating layer shows an alloy character. The results show that, the oxidation of methanol is catalysed by the formation of copper oxides on the surface of the Cu / NP / Iron.
