英文摘要	a novel polytetrafluoroethylene (ptfe)-reinforced multilayer self-humidifying composite membrane is developed. the membrane is composed of nafion-impregnated porous ptfe composite as the central layer and nanosized sio2 supported pt catalyst imbedded into nafion as the two side layers. the proton exchange membrane (pem) fuel cells employing the self-humidifying membrane (20 mu m thick) under dry h-2/o-2 gave a peak power density of 0.95 w/cm(2) and an open-circuit voltage of 1.032 v. the good membrane performance is attributed to hygroscopic pt-sio2 catalyst at the two side layers, which results in enhanced anode side self-humidification function and decreased cathode polarization.
