摘要

Sulfonated poly(ether sulfone) copolymer(PES 60) and its partially fluorinated analogue (F-PES 60)were synthesized via the nucleophilic aromatic polyconden-sation of commercially available monomers to make a poly-mer electrolyte membrane and a binding material in theelectrodes of a membrane-electrode assembly (MEA). PES 60and F-PES 60 showed proton conductivities of 0.091 and0.094 S/cm, respectively, in water at room temperature. Thecopolymer was dissolved in the mixture of alcohol and waterto get a 1 wt % binder solution. A catalyst slurry was pre-pared with the copolymer solution and sprayed on the copol- ymer (PES 60 or F-PES 60) membrane to obtain a MEA. BothPES 60 and F-PES 60 based MEAs were fabricated with differ-ent amounts of their binder in the electrodes to examine theeffect of the copolymer binder in the catalyst layer on the fuelcell performance. The MEA with 2 wt % copolymer binder inthe electrodes showed the best fuel cell performance. 2009 Wiley Periodicals, Inc. J Appl Polym Sci 113: 2499-2506,2009
