New materials and deposition methods are being sought for electrolyte membranes for use in proton exchange membrane fuel cells. Perfluorosulfonic acids associate high conductivity and high chemical stability and much research is dedicated to developing newer generations of short side chain perfluorosulfonic acid (PFSA) of low equivalent weight owing to their advantageously higher glass transition temperature and proton conductivity. In this work, the effects of the side-chain length on the properties of electrospun long- and short-side-chain PFSA are compared.
