Proton exchange membranes have been attracting considerable attention due to their important application in fuel cell systems. Partially fluorinated polymer membranes are expected to be a promising candidate for this fuel cell systems because of their high thermal properties, low preparation cost and working at high temperatures. Here, we report the synthesis, characterization and electrochemical properties of four different partially fluorinated-sulfonated poly(bipheylene-co-sulfone)ether membranes containing perfluorocyclobutane membranes for fuel cell applications: random, block, branch-random and branch block-copolymers. The sulfonated membranes were analyzed in terms of electrochemical properties-ion exchange capacity (IEC), water uptake, and proton conductivity. |
