제목 Synthesis and characterization of Poly(arylene thioether sulfone) for proton conducting Electrolyte Membranes
초록 The polyperfluorinated sulfonic acid membranes are state-of-the-art PEMs, used for both hydrogen and methanol fuel cells. However, some specific limitations exist for Nafion type membranes which include low conductivity at high temperatures and low humidity as well as high methanol permeability that decrease fuel efficiency. We synthesized a non-fluorine resin poly (arylene thioether sulfone) and compared to Nafion.The composition and incorporation of the sulfonated repeat unit into the copolymers were confirmed by ¹H-NMR and Fourier transform infrared Spectroscopy. The memebranes were prepared from the casting and the degree of sulfonation were controlled by using various the ratio of 3,3-disulfonate-4,4’-dichlorodiphenyl sulfone. Detailed results will be discuss additional characteristics of these copolymers using ion exchange capacity, water uptake, ion conductivity, permeability.
