Abstract: PtRu/C (20%-10% in mass fraction) catalysts for direct methanol fuel cell(DMFCs) were prepared by three different methods, XRD and TEM were used to characterize the lattice parameter, particle size and distribution of PtRu metal particles. Polarization experiments of single DMFCs were used to investigate the activity of different PtRu/C anode catalysts directly. It is found that the PtRu/C synthesized in a mixture solvent including ethylene glycol, water and isopropanol has a smaller metal particle size and more improved interaction between Pt and Ru. The single DMFC adopting the PtRu/Cas anode catalyst shows a better performance.

Key words: PtRu/C catalyst, Catalyst preparation, Direct methanol fuel cells(DMFCs)
