Abstract
Disclosed is a process of preparing an ion exchange membrane which comprises adding a highly hydrophilic solvent into a solution of an ion exchange resin containing an ion exchange group on the polymer chain, placing the solution into a membrane-forming vessel and forming a membrane by removing the solvent. The ion exchange membrane prepared in accordance with the present invention exhibits the high degree of orientation so that the ionic conductivity can be elevated to provide the satisfactory cell performance.
