ABSTRACT:
In a filter press membrane electrolytic cell having a plurality of electrodes, each electrode being of predetermined thickness and separated from the adjacent electrode by an ion-selective permeable membrane all supported by a frame and in fluid flow communication with a gas-liquid disengager there is provided an improved electrolyte return line having a first portion external to each electrode and a second portion internal to each electrode, wherein the second portion fits within the predetermined thickness in a structurally reinforcing manner so that the structural rigidity of the electrode is increased while the electrode surface area available for fluid contact is maximized.
