主 题：Anion exchange membrane Fuel cell Thiol-ene click reaction Water uptake Comb-shaped architecture
摘 要：Significant advancement in anion exchange membrane(AEM)fuel cell(AEMFC)technology is important in the field of renewable *** with comb-shaped architectures have attracted considerable research interest because of some unique features,including high anion conductivity,low swelling,and high alkaline ***,we report preparation,characterization,and performance evaluation of a novel comb-shaped cross-linked AEM synthesized by the thiol-ene click and Menshutkin *** prepared ionomer decreases the trade-off between the water uptake and the *** thiol-ene click reaction was used to synthesize the 1,14-di(1H-imidazol-1-yl)-6,9-dioxa-3,12-dithiatetradecane(IDDT)*** was then introduced into the brominated poly(2,6-dimethyl-1,4-phenylene oxide)backbone by the Menshutkin *** prepared ionomers show high thermomechanical stability,which is needed in AEMFC *** CLINK-15-100 membrane(ion exchange capacity 1.23 mmol/g)shows relatively good conductivities of 19.66 and 34.91 mS/cm at 30 and 60℃,***,the membrane shows water uptake of only 14.22%at room temperature,which is considerably lower than many previously reported *** 16 days of alkaline treatment in 1 M NaOH solution at 60℃,the CLINK-15-100 membrane retains 77%of its initial conductivity,which is much better than the traditional quaternized poly(2,6-dimethyl-1,4-phenylene oxide)membrane.
