Abstract

A unique, current conducting bipolar separator in a cell for electrolysis of chlorides makes multiple contact with the anodes and cathodes bonded to an ion transporting membrane in an electrolysis cell. Each side of the separator plate includes a plurality of electrode contacting, current conducting ribs or projections which also define a plurality of flow channels to allow fluid transport and good flow distribution. The projections or ribs on opposite sides of the separator plates are angularly disposed relative to each other so that the membrane is supported on one side by ribs of one separator and on the other side by the ribs from another separator which are angularly disposed to the first group. The intersection of the ribs on opposite sides of the membrane, thus, establishes a plurality of pressure areas or bearing surfaces which support the membrane without deforming it and without requiring very precise registration and alignment of the ribs.
