Abstract

Abstract Nanostructured composites of electron and proton conducting materials were fabricated via simultaneous electrospinning of Nafion and {PANI} solutions on a rotating collector for application as fuel cell catalyst supports. Poly (ethylene oxide) (PEO) was used as a carrier polymer to enhance chain entanglements and therefore the electrospinnability of both solutions. Dual nanofiber mat with a Nafion/PANI composition of 50/50 wt% was prepared. Post electrospinning annealing at 150
