Synthesis and Properties of Polybenzimidazoles and Their Nanocomposite Membranes for Fuel Cell Applications

摘要：

Introduction. Polybenzimidazole (PBI) is a very promising material for high-temperature (>100℃) fuel cell applications because of its high thermal stability and good mechanical properties. In addition, PBI doped with strong acids has stable proton conductivity at temperatures higher than 100 ℃.In this study, we have prepared novel PBI/silica hybrid membranes using the tetraethyl orthosilicate (TEOS) precursor via sol-gel process in a PBI solution, followed by solution casting. The PBI used in this research is an amorphous,organosoluble fluorine-containing PBI.
