Ion exchange membrane for reverse electrodialysis device and reverse electrodialysis device including the same

摘要

This invention relates to an ion exchange membrane for a reverse electrodialysis (RED) device, a manufacturing method thereof and a reverse electrodialysis device including the ion exchange membrane, wherein the ion exchange membrane includes a porous polymer substrate; and a polymer electrolyte incorporated into pores of the porous polymer substrate. According to this invention, cation and anion exchange membranes for a reverse electrodialysis device have superior ion conductivity and thus can minimize membrane resistance, thereby remarkably improving maximum power density of the reverse electrodialysis device, and also have high water resistance and heat resistance, making it possible to stably operate the reverse electrodialysis device.
