摘要：

The quaternary 1,4-diazabicyclo-[2.2.2]-octane (DABCO) polysulfone (QDPSU) was synthesised. A thin (30 mu m) composite membrane based on polytetrafluoroethylene (PTFE) and QDPSU was obtained by impregnation method of QDPSU solution in PTFE support. SEM images revealed a dense and homogenous structure of PTFE-QDPSU membrane. The PTFE-QDPSU composite membrane showed good mechanical strength (a 32 MPa maximum load), and a water uptake of 61 +/- 3% and a 17 +/- 2% swelling degree. An ionic conductivity of 0.051 S cm(-1) was achieved at 50 degrees C and 100% RH. Preliminary data of a single MEA gave power outputs of 146 and 103 mW cm(-2) with oxygen and air respectively.
