Novel highly proton conductive sulfonated poly(p-phenylene) from 2,5-dichloro-4-(phenoxypropyl)benzophenone as proton exchange membranes for fuel cell applications.
A novel sulfonated poly(4-phenoxypropylbenzoyl-1,4-phenylene) introducing a flexible alkyl chain was synthesized and achieved high proton conductivity even at low humidity (SPP: 0.077 S cm(-1), Nafion 112: 0.029 S cm(-1) at 80 degrees C 50% RH).
