Abstract
Abstract A PACKED BED TYPE OF ELECTROCHEMICAL CELL COMPRISES A LARGE NUMBER OF ISOLATED CONDUCTING UNITS SEPARATED BY NON-CONDUCTING MEANS, THE BED BEING ARRANGED BETWEEN TWO ELECTRODES AND ELECTROLYTE MADE TO FLOW THROUGH THE BED. IN CONSQUENCE THE CELL, IN OPERATION, COMPRISES A MULTIPLICITY OF SMALL BIPOLAR CELLS DISTRIBUTED THROUGHOUT THE BED. THE BED MAY BE CYLINDRICAL OR RECTANGUALR OR OF ANY DESIRED FORM AND MAY COMPRISE A MIXTURE OF CONDUCTING AND NON-CONDUCTING PARTICLES. IF THE PARTICELES ARE OF SIMILAR SIZE OR SIZE DISTRIBUTION, THEN ABOUT TWICE THE QUANTITY (VOLUME) OF NON-CONDUCTING PARTICLES AS CONDUCTING PARTICLES ARE PROBABLY REQUIRED.
