This paper deals with a vapour-feed direct methanol fuel cell (DMFC) based on a Nafion 117{reg_sign} solid polymer electrolyte. Pt-Ru/C and Pt/C catalysts were employed for methanol oxidation and oxygen reduction, respectively. Structure and surface chemistry of catalysts were investigated by X-ray powder diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). Membrane/electrode assembly (M&E) was prepared by using a {open_quotes}paste process{close_quotes} method. Electrical power densities of about 150 mW cm{sup -2} were obtained at 95{degrees} C with Pt loadings of 0.8 and 0.5 mg cm{sup -2} at anode and cathode respectively.
