Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
156 words
An electrolytic cell for the generation of gaseous chlorine comprising: a cathode chamber, an anode chamber for receiving therein an aqueous solution of a metallic chloride, the walls of said anode chamber separating said cathode chamber from said anode chamber being at least partially formed of a porous ceramic material which extends into both cathode chamber and the anode chamber, an anode mounted in said anode chamber extending into the aqueous solution when it is placed therein, a cathode in said cathode chamber deposited on said ceramic material in said cathode chamber and being in communication with said anode chamber through pores in said ceramic material, said cathode comprising a porous metallic coating deposited on said ceramic material and having a porosity greater than the porosity of said ceramic material, means for supplying a DC voltage across said anode and said cathode to produce gaseous chlorine in said anode chamber; and an outlet in each chamber.
