| 英文摘要 | an ultrathin, low cost and high performance reinforced composite membrane ( 20 mm, thick) based on disulfonated poly( arylene ether sulfone)-impregnated polytetrafluoroethylene ( ptfe) for polymer electrolyte membrane (pem) fuel cell application was investigated. for comparison, ptfe-reinforced nafion(r) membrane (nafion/ptfe), pristine disulfonated poly( arylene ether sulfone) membrane (spsu) and recast nafion112 membrane (rn112) membrane were employed. the peak power density of a single pem fuel cell employing the composite membrane (spsu/ ptfe) reached 2.4 w cm 22, twice that of the rn112 membrane. the spsu/ ptfe membrane structure was characterized and confirmed by scanning electron microscopy (sem) coupled with energy dispersive spectroscopy (eds), and fourier transform infrared ( ftir) spectroscopy. the improved interface compatibilty of the two components in the spsu/ ptfe membrane, reflected by enhanced morphology/ surface property, was ascribed to the surface pre-treatment of microporous expanded ptfe and the presence of the n-butanol auxiliary solvent in the membrane fabrication process. the excellent single cell performance employing our spsu/ ptfe membrane was attributed to the implementation of ultrathin ptfe-reinforced membrane with low areal resistance and utilization of a high proton conductive spsu ionomer. our spsu/ ptfe membrane might indicate or pave a way of fluorine-less or non-fluorinated ionomer membranes to replace nafion(r) membranes for pem fuel cell applications. |
