1Anion Exchange Membrane Based on Interpenetrating Polymer Network with Ultrahigh Ion Conductivity and Excellent Stability for Alkaline Fuel Cell显示文摘A high-performance anion exchange membrane(AEM)is critical for the development of alkaline fuel cell.In this work,AEMs with an interpenetrating polymer network(IPN)are synthesized.An electron microscope clearly reveals a highly efficient“ion channel”network,which is constructed with a small amount of cation exchange groups.This specially designed ion channel leads to extraordinary hydroxide conductivity(e.g.,257.8 mS cm^(-1) at 80℃)of IPN AEMs at moderate ion exchange capacity(IEC=1:75 mmol g^(-1)),as well as excellent long-term alkaline stability at harsh condition which showed that 81%of original conductivity can be retained after a long time for 1248 hours.Moreover,a remarkable peak power density of 1.20 Wcm^(-2)(0.1 MPa backpressure)with nonprecious metal(FeNx-CNTs)as oxygen reduction reaction(ORR)catalyst in a fuel cell test was achieved.This work offers a general strategy to prepare high-performance AEMs based on IPN structure design.Lingping Zeng Qian He Yunchuan Liao Shangyi Kuang Jianchuan Wang Wei Ding Qiang Liao Zidong Wei 2020Research2020,,1:2
