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.
