제목 Preparation and Characterization of Crosslinked Sulfonated Poly(arylene ether sulfone) Membranes for Polymer Electrolyte Membrane Fuel Cells
초록 A proton exchange membrane (PEM) serves as a solid electrolyte in a fuel cell, separating the anode from the cathode compartments. This membrane is required to exhibit high proton conductivities and a good resistance to the high temperature, humid and oxidative environment of a fuel cell. In this study, a sulfonated poly(arylene ether sulfone) (SPAES) was synthesized by direct copolymerization and additionally crosslinked by using a divinyl benzene (DVB). The structure of crosslinked membranes was investigated by TGA, 1H-NMR and FT-IR, which showed that SPAES was effectively crosslinked with DVB. In addition, the properties of crosslinking membranes were also evaluated in terms of proton conductivity, thermal and hydrolytic stability, and oxidative stability.
