Reverse electrodialysis (RED) is green energy technologies to produce electric power using the salinity gradient. The salinity gradient generates chemical potential difference by transport of ions through the membranes. In RED system, anion exchange membrane (AEM) and cation exchange membrane (CEM) play a major role in transporting cation (Na+) and anion (Cl-), respectively. Significant technical issue is how to enhance conductivity and permselectivity of membrane simultaneously in the system. In this study, we characterized influences of cationic functional groups on AEM. We evaluated conductivity and permselectivity of AEM introduced three types of cationic salt functional groups.
