Platinum electrocatalysts for fuel cells based on individual oxides Pt/SnO 2 and Pt/TiO 2 and their solid solutions Pt/Ti 1-xM xO 2 (M = Ru, Nb) and Pt/Sn 1-xM'xO 2-δ (M' = Sb, Ru) were prepared. The influence of the composition of the oxide supports on the activity of the supported platinum catalysts in electrooxidation of methanol and hydrogen in the presence of CO was studied. The prepared platinum catalysts supported on solid solutions of tin dioxide Sn 1-xM xO 2-δ(M = Sb, Ru; x = 0.4-0.9) and Ti 1-xM xO 2 (M = Ru, Nb; x = 0.7) exhibited higher tolerance to CO poisoning and higher activities for methanol electrooxidation than commercial Pt,Ru catalysts on carbon support. The use of the proposed oxide supported catalysts in hydrogen and direct methanol fuel cells improved their performances in comparison with that for the fuel cells with traditional Pt,Ru catalysts on carbon support.
