Polyaniline fiber (PANI) was synthesized by chemical interfacial method and utilized to fabricate Vulcan-Polyaniline (C-PANI) composite. PtSn(70:30) nanoparticles are reduced on C-PANI composite and the performance of the PtSn(70:30)/C-PANI and commercial PtRu/C, as anode catalysts, are compared in a passive direct methanol fuel cell. The DMFC test results indicate that the membrane electrode assembly (MEA) prepared from PtSn(70:30)/C-PANI anode exhibits better performance in terms of maximum power density and stability. Also the methanol crossover in the presence of PtSn(70:30)/C-PANI has been reduced by 42%. In comparison with the commercial PtRu/C catalyst, the optimal PtSn(70:30)/C-PANI catalyst exhibits superior activity toward methanol oxidation.
