Carbon-supported catalyst with varying atomic ratio of Pt to Ti, namely, 1:1, 2:1, and 3:1, is prepared by sol-gel method and its electrocatalytic activity toward oxygen-reduction reaction (ORR) is evaluated for the application in polymer electrolyte fuel cells (PEFCs). The optimum atomic ratio of Pt to Ti in and annealing temperature are established by cyclic voltammetry and fuel-cell-polarization studies. annealed at with Pt and Ti in atomic ratio of 2:1, namely, (2:1), shows enhanced electrocatalytic activity toward ORR. It is found that the incorporation of with Pt ameliorates both electrocatalytic activity and stability of cathode in relation to pristine Pt cathode, currently being used in PEFCs. A power density of is achieved at 0.6 V for the PEFC with (2:1) as compared with at 0.6 V achieved with the PEFC comprising Pt/C as cathode catalyst while operating under identical conditions. Interestingly, carbon-supported cathode exhibits only 6% loss in electrochemical surface area after 5000 potential cycles while it is as high as 25% for Pt/C.
