• Ethanol oxidation on platinum-ruthenium binary (PtRu) electrocatalyst loaded on a composite of poly(N-methylpyrrole) and Nafion (PNMPY) has been investigated. Two kinds of methods, chemical reduction and electrodeposition, were applied to load PtRu metallic species on catalyst supports. The PtRu electrocatalyst prepared by the former method exhibited higher initial activity for ethanol oxidation per unit weight of Pt than that prepared by the latter method. The dependence of Ru/(Pt+Ru) ratio on catalytic properties was examined for the electrocatalysts prepared by the electrodeposition method. The initial activity increased as the increase of Ru/(Pt+Ru) ratio. In contrast, the long-term activity showed rather complicated dependence toward Ru/(Pt+Ru) ratio.
