| 英文摘要 | in this paper, an effective method to cover the conductivity loss of nafion/sio2 through sulfonation and its mechanism are studied. nafion/sio2 composite membranes are prepared via an in-situ sol gel route, and then sulfonated with concentrated sulfuric acid (marked as nafion/s-sio2). the effects of the sulfonation on properties of the nafion/sio2 composite membrane are investigated. the results show that sulfonation can improve the proton conductivity of the nafion/sio2 effectively, though it brings water-uptake loss to the composite membrane to some extent simultaneously. according to the results of ft-ir, uv resonance raman spectroscopy, si-29 solid-state mas nmr and xrd, it's proved that higher conductivity of nafion/s-sio2 should be relevant to hydrogen bonds & chemical bonds between sio2 nano particles and sulfuric acid molecules. while, lower water uptake & swelling ratio should be caused by hydroxyl-elimination on the surface of sio2 nanoparticles during sulfonation. single cell tests show that the performance of nafion/s-sio2 composite membranes substantially exceeds nafion/sio2 at 110 degrees c and 59%rh, and in the initial testing stage no performance reduction is observed. copyright (c) 2010, hydrogen energy publications, llc. published by elsevier ltd. all rights reserved. |
