This study shows the fabrication and characterization of poly(biphenylene-co-sulfone)ether membranes containing perfluorocyclobutane(PFCB) groups for fuel cell applications. These proton-conducting membranes were prepared through three synthetic steps: synthesis of trifluorovinylether-terminated monomers, thermal cycloaddition and post-sulfonation. Fabricated proton-conducting membranes were evaluatedfor electrochemical properties such as proton conductivity, ion exchange capacity(IEC), and water uptake. |
