英文摘要a novel technique in controlling the size of sio2 nano-particles in the preparation of nafion/sio2 composite membranes via in situ solgel method, as well as the effects of nano-particle size on membrane properties and cell performance, is reported in this paper. nafion/sio2 composite membranes containing sio2 nano-particles with four different diameters (5 +/- 0.5, 7 +/- 0.5, 10 +/- 1, and 15 +/- 2nm) are fabricated by altering the reactant concentrations during in situ solgel reaction. sequentially, size effects of sio2 nano-particles on membrane properties and cell performance are investigated by sem/edax, tem, tga, mechanical tensile, and single cell tests, etc. the results suggest that 10nm is a critical diameter for sio2 incorporated into nafion matrix, exhibiting desirable physico-chemical properties for operation at elevated temperature and low humidity. at 110 degrees c and 59% rh, the output voltage of the cell equipped with nafion/sio2 (10nm) obtains an output voltage of 0.625v at 600ma/cm2, which is 50mv higher than that of unmodified nafion. copyright (c) 2010 john wiley & sons, ltd.
