Abstract

A series of sulfonated poly(phenylene arylene) membranes were successfully prepared from 2, 5-dichloro-3´-sulfobenzophenone (DCSB) and 2, 2´-bis[4-(4-chlorobenzoyl)phenoxyl] perfluoropropane (BCPPF) through Ni(0)-catalyzed copolymerization. The membranes were obtained by solution casting method. They showed good mechanical strength and almost isotropic swelling behavior. Membrane No.2 with an IEC of 2.0 meg/q showed high polymer electrolyte fuel cell (PEFC) performance data of open circuit voltage (OCV) of 0.95 V, cell voltage at 0.5 Acm^-2 (V_0.5=0.74 V), maximum output (W_max=0.96 Wcm^-2) at 90°C, 80% relative humidity condition.
