Abstract
An electrolytic cell is provided suitable for chloralkali electrolysis comprising a housing; an anolyte chamber in the housing; an anode disposed within the anolyte chamber; at least one cathode spaced from the anode with at least one portion of the cathode being adjacent said anolyte chamber, the cathode including a cathode chamber, means to supply and remove oxygen and remove alkali hydroxide catholyte from the cathode chamber; and a multi-layer wall defining a boundary between the anolyte chamber and the interior of the cathode chamber comprising a permeable separator material adjacent the anolyte chamber, a foraminous electrically conductive supporting material adjacent the interior of the cathode chamber, and at least partially hydrophobic electrocatalytically active material suitable for the reduction of oxygen adjacent the separator material and the supporting material.
