Two types of carbon supported Pt-Ni nanoparticles were fabricated as catalysts for the cathode part of a direct methanol fuel cell, and were characterized by X-ray diffraction, transmission electron microscopy and cyclic voltammetry analyses. TEM and XRD analyses pointed to a good dispersion of the catalysts with carbon black and carbon nanotubes (CNTs) having sizes of ca. 2-6 nm, which is very important for supporting catalysts of the methanol fuel cell. CV analysis showed that the catalytic activity of a Pt-Ni/CNTs catalyst is more efficient than that of other catalysts. We also noticed that it is more appropriate to use a glassy carbon electrode rather than carbon paper as the working electrode for the methanol electrooxidation of Pt Ni/CNTs catalysts.
