ABSTRACT:
The present invention is a process for modifying a fluorinated ion exchange membrane by irradiation of the membrane with a sufficient dose of non-spark-producing radiation to increase water absorption and/or ionic conductivity of the membrane. The membranes are particularly useful in fuel cells and chloralkali cells.
