Patent ID: 7927471

Claim:
An ion exchange electrolytic cell comprising: an anode chamber including an anode and a cathode chamber including a cathode separated by an ion exchange membrane, and an anode current collector and a cathode current collector; at least one of the anode and the cathode being a three-dimensional electrode for electrolysis including a plate-shaped metal electrode substrate supporting electrode catalyst and having a plurality of snicks, and a plurality of elastic electroconductive sections which are formed by bending the plurality of the snicks toward the same direction with respect to the electrode substrate, and the electrode substrate being in tight contact with the ion exchange membrane, and the elastic electroconductive sections being in contact with at least one of the anode current collector and the cathode current collector, thereby providing resilience to the entire electrode without mounting an additional resilient element so that the electrode is retained at the fixed position by means of its own elasticity free of any additional resilient element.
