Electrolytic apparatus including bipolar electrodes defining an enclosed volume and held in a nonconductive frame

Abstract

Abstract BIPOLAR HOLLOW PLATE ELECTRODE UNIT INCLUDING AN ELECTRICALLY CONDUCTIVE SPACER BODY HAVING A PAIR OF OPPOSED END FACE PORTIONS CARRYING RESPECTIVELY A CATHODE PLATE ELECTRODE AND AN ANODE PLATE ELECTRODE IN TRANSVERSE SPACED RELATION TO DEFINE THEREBY A HOLLOW SPACE BETWEEN SAID ELECTRODES, SASID PLATE ELECTRODES BEING ELECTRICALLY INTERCONNECTED THROUGH SAID SPACER BODY AT SAID END FACE PORTIONS, THE SPACER BODY IN TURN BEING CARRIED IN AN ELECTRICALLY NON-CONDUCTIVE SPACER FRAME PERIPHERALLY ENCLOSING SAID SPACER BODY AND SAID PLATE ELECTRODES, SAID FRAME HAVING A CORRESPONDING PAIR OF OPPOSED END FACE PORTIONS AND BEING OF SLIGHTLY GREATER TRANSVERSE THICKNESS THAN THAT OF SAID BODY SUCH THAT THE CORRESPONDING END FACE PORTION OF SAID FRAME ADJACENT THE END FACE PORTION OF SAID BODY CARRYING SAID CATHODE PLATE ELECTRODE EXTENDS SLIGHTLY BEYOND SAID CATHODE PLATE ELECTRODE A GIVEN TRANSVERSE DISTANCE, PREFERABLY WITH THE CATHODE BEING A POROUS, E.G. WIRE GUAZE, PLAT ELECTRODE AND WITH A SEPARATING WALL DISPOSED IN THE HOLLOW SPACE BETWEEN THE PLATE ELECTRODES TO DEFINE A CATHOLYTE SPACE ADAJCENT THE CATHODE, E.G. WITH THEPOROUS CATHODE BEING COVERED WITH A DIAPHRAGM IN CONTACT WITH THE SURFACE THEREOF REMOTE FROM THE CATHOLYTE SPACE, AND PREFERABLY WITH THE ANODE BEING IN THE FORM OF AN IMPERFORATE TITANIUM PLATE CONTAINING A NOBLE METAL COATING THEREON ON THE SIDE THEREOF REMOTE FROM THE CATHODE OF THE GIVEN BIPOLAR ELECTRODE, E.G. WITH THE OPPOSITE SIDE OF THE ANODE HAVING AN ELECTRICALLY HIGHLY CONDUCTIVE METAL COATING THEREON TO ENHANCE THE ELECTRICAL CONDUCTIVITY OF THE ANODE AND PERIPHERALLY BEING IN CONTACT WITH THE CORRESPONDING SPACER BODY END FACE PORTION ADJACENT THERETO AND PREFERABLY WITH SUCH CONNECTION BETWEEN THE ANODE AND THE SPACER BODY BEING IN THE FORM OF AN ELECTRICALLY HIGHLY CONDUCTIVE SOLDERED JOINT; AND ELECTRO-CHEMICAL CELL ARRANGEMENT FOR CARRYING OUT ELECTROCHEMICAL REACTIONS USING AN AQUEOUS ALKALI METAL HALIDE SOLUTION AS ELECTROLYTE, IN THE FORM OF AN AGGREGATE OF INTERNALLY ELECTRICALLY INTERCONNECTED CELLS MADE UP OF SUCH BIPOLAR UNITS IN SIDE-BY-SIDE DISPOSITION WITH APPROPRIATE END ELECTRODES AND CURRENT TERMINAL MEANS TO COMPLETE THE SYSTEM.
