title = "Composite nanofiber network membranes for PEM fuel cells",
abstract = "A new class of proton-exchange membranes has been developed and characterized, where an interconnected network of proton conducting polymer nanofibers is embedded in an inert (nonconducting) polymer matrix In the present study the nanofiber network membrane contained electrospun fibers from sulfonated poly(arylene ether sulfone) solutions (with/without sulfonated polyhedral oligomeric silsesquioxane, sPOSS). The membranes were characterized in terms of morphology, proton conductivity, and water uptake. In-plane proton conductivity was measured using a BekkTech cell that was placed in a controlled temperature/humidity chamber. The data show: (1) There was a modest increase in nanofiber > 50%.membrane conductivity when the IEC of the fibers was increased from 2.1 to 2.6 mmol/g (in the absence of sPOSS), (2) There was a substantial increase in membrane conductivity when sPOSS was added to the fibers, and (3) The proton conductivity of the sPOSS-loaded membranes was significantly higher than that for a commercial Nafion 212 sample at 30°C for a relative humidity",
