Polyelectrolytes Based on Speek/TiO2 Nanocomposites for Direct Ethanol Fuel Cells Applications
Abstract
Proton-conducting nanocomposite membranes consisting of poly(ether ether ketone) sulfonated (SPEEK) and titanium oxide (TiO2) were prepared by sol-gel technique. The TiO2 incorporation effect on membrane properties such as ethanol uptake, pervaporation and proton conductivity was investigated.
