Abstract : The Pt/FePO₄ thin-film electrodes consisting of nanocrystalline Pt and amorphous FePO₄ were fabricated. Nanostructured Pt/FePO₄ thin-film electrodes showed higher catalytic activity and better stability than pure Pt electrodes for methanol oxidation. The electrocatalytic properties of FePO₄/Pt/C nanocomposites were also examined. The FePO₄/Pt/C nanocomposites showed no initial degradation of electrocatalytic properties and exhibited enhanced long-term stability.
