Novel Polyphenylquinoxaline and Polybenzimidazole Proton Exchange Membranes For High Temperature Fuel Cell Systems
… conducting ability.</p><p>Recently, a novel process was developed to produce gel membranes suitable for high temperature PEMFCs where polyphosphoric acid (PPA) is used as a condensation agent and as a casting solvent in a one-pot synthesis of polymer suitable for proton exchange membranes. …

Synthesis and Chacterization of Novel Polybenzimidazoles and High-Solids Meta-Polybenzimidazoles
… and proton conductivity. Recently, a new process was developed to produce polybenzimidazole gel membranes for use in high temperature PEM fuel cell systems, which uses polyphosphoric acid (PPA) as both the polycondensation agent and the casting solvent. This one-pot process, called the …
