Hybrid Proton-Conducting Membranes as Fuel Cells Solid Polyelectrolytes

Abstract

A series of novel hybrid organic-inorganic membranes based on sulfonated naphthalimides and phosphotungstic acid N-methylpyrrolidone were prepared from a NMP solution. These materials, composed of two proton-conducting components, have good mechanical properties, high ionic conductivities (10.5×10−2S∕cm at 80°C) and good fuel cell performances at 70°C.
