Abstract

Mixed-oxide coated Ti0.8Mo0.2O2-C composite supported 20 wt% Pt electrocatalysts with Ti0.8Mo0.2O2/C=75/25 mass ratio were developed for CO tolerance of polymer electrolyte membrane fuel cell (PEMFC) anode. Studies of the structure, composition and stability, as well as the results of COads stripping confirmed that the mixed oxide composite support and the electrocatalyst prepared for this study show the well-documented characteristics of the Pt/Ti1-xMoxO2-C systems with enhanced CO tolerance compared to the Pt/C catalyst.
