| Abstract | Sputter deposition was investigated as a tool for manufacturing proton-exchange membrane fuel cell (PEMFC) electrodes with improved performance and better catalyst utilization vs. commercial electrode. Nanosized (diameter 2-5 nm) platinum clusters were deposited on gas diffusion electrodes (carbon paper+PTFE/C diffusive layer). The activity for methanol oxidation was increased about 14 times compared to commercial catalyst, with loading <0.02 mg cm-2. SEM-FEG characterization and cyclic voltammetry were carried out to study the morphology, and the behavior of the Pt clusters as cathodic electrocatalyst of a polymer electrolyte fuel cell. © 2005 Elsevier B.V.
