Abstract: A method of producing an ion-exchange membrane suitable for use in an electrolytic cell in which the membrane is expanded by stretching at elevated temperature to increase the surface area per unit weight of the membrane. The membrane may be annealed at elevated temperature, and may be cooled while restrained in the expanded state. The membrane when used in an electrolytic cell remains taut and unwrinkled and leads to reduced voltage operation of the cell.

Abstract: An alkali metal salt solution is electrolyzed in an electrolytic cell with at least two electrode compartments adapted to being separated by a membrane. At least one electrode compartment contains at least one means defining a space adapted to receive a portion of membrane surface during operation of the cell. By maintaining the pressure higher in one electrode compartment than the other the membrane portion is pushed toward and into the membrane receiving space such that any wrinkles formed on the membrane are removed.
