摘要: Abstract Polyaniline fiber (PANI) was synthesized and utilized to fabricate a vulcan–polyaniline (C-PANI) composite. Pt/C-PANI PtSn/C-PANI electro-catalysts with different Pt:Sn atomic ratios were prepared by the impregnation method. These electro-catalysts, along commercial PtRu/C (Electrochem), characterized respect their structural electrochemical properties in methanol oxidation reaction (MOR). PtSn(70:30)/C-PANI showed excellent performance MOR, obtained maximum current density being about 40% 50% higher than that for Pt/C-PANI, respectively. It also found CO tolerance stability of considerably PtRu/C. Finally, these two materials compared passive direct fuel cell (DMFC). The DMFC test results demonstrated membrane electrode assembly (MEA) using anode catalyst performed more satisfactorily terms power lower crossover.
