Abstract

See full text

Disclosed herein are a structure of an ion exchange membrane comprising the ion exchange membrane and at least one ion-conductive thin layer having a lower glass transition temperature than that of the ion exchange membrane on at least one surface of the membrane. According to the present invention, an electrochemical cell can be formed of which an ion exchange membrane and electrodes may be sufficiently bonded to maximize the cell performance.
