The design of hybrid organic−inorganic membranes using an electrospinning approach is discussed. The sulfonated silica-based membranes exhibit proton conductivity comparable to Nafion at high temperature and low humidity and have better mechanical properties. This behavior is related to the specific microstructure of the membrane, which is reached via the electrospinning. The membrane contains polymer fibers surrounded by functionalized large silica domains.
