Abstract
A bipolar-electrode electrolytic cell is disclosed, which is to be used in electrolysis of an electrolytic solution having a high electric resistance and including at least two diaphragms positioned to form a plurality of electrode compartments comprising two outer compartments defined between the side walls of the electrolytic cell and the diaphragms positioned closest to the cell walls having a single electrode and at least one electrode compartment having two same-polar electrodes on both sides thereof, each of said electrodes being placed on a diaphragm such that different-polar electrodes are positioned at opposing sides of the diaphragm, wherein the distance between same-polar electrodes within the same compartment is sufficiently large such that electrolysis therebetween does not substantially occur and wherein two of said electrodes at the terminal ends of the series connected electrolytic cell, an anode and a cathode, being further electrically connected to an anode collector and a cathode collector, respectively, and each of the remaining anode electrodes and cathode electrodes is further connected to a different-polar electrode, respectively, which face the same direction and are placed on adjacent diaphragms.
