Copolymerization of ethylene, tetrafluoroethylene, and an olefin-containing fluorosulfonyl fluoride: Synthesis of high-proton-conductive membranes for fuel-cell applications

Excellent thermal stability and mechanical properties are exhibited by high-proton-conductive membranes synthesized by a facile copolymerization of tetrafluoro-ethylene, ethylene, and CH2=CHCF2CF 2O-CF2CF2SO2F (see scheme and AFM image). These membranes have been successfully used in a direct MeOH fuel cell.
