| 英文摘要 | a self-humidifying composite membrane based on nafion (r) hybrid with sio2 supported sulfated zirconia particles (sio2-sz) was fabricated and investigated for fuel cell applications. the bi-functional sio2-sz particles, possessing hygroscopic property and high proton conductivity, were homemade and as the additive incorporated into our composite membrane. x-ray diffraction (xrd) and fourier infrared spectrum (ft-ir) techniques were employed to characterize the structure of sio2-sz particles. scanning electronic microscopy (sem) and energy dispersive spectroscopy (eds) measurements were conducted to study the morphology of composite membrane. to verify the advantages of nafion (r)/sio2-sz composite membrane, the iec value, water uptake, proton conductivity, single cell performance and areal resistance were compared with nafion (r)/sio2 membrane and recast nafion (r) membrane. the single cell employing our nafion (r)/sio2-sz membrane exhibited the highest peak power density of 0.98 wcm(-2) under dry operation condition in comparison with 0.74 wcm(-2) of nafion (r)/sio2 membrane and 0.64 wcm(-2) of recast nafion (r) membrane, respectively. the improved performance was attributed to the introduction of sio2-sz particles, whose high proton conductivity and good water adsorbing/retaining function under dry operation condition, could facilitate proton transfer and water balance in the membrane. crown copyright (c) 2008 published by elsevier b.v. all rights reserved. |
