<P>PROBLEM TO BE SOLVED: To provide an ion exchange system electrolytic cell where the renewal of a cathode is remarkably simply practicable and to provide a method of recovering the performance of the cathode. Ž<P>SOLUTION: In the ion exchange membrane system electrolytic cell where an anodic chamber and a cathodic chamber are separated by an ion exchange membrane, the cathode chamber is provided with the cathode formed by laminating a first expand metal and a second expand metal, and the second expand metal nearer to the ion exchange membrane has a notch width, minor axis and major axis which are smaller than half of that of the first expand metal. The method of manufacturing the ion exchange membrane system electrolytic cell is provided. When the cathode is degraded during the electrolysis from the start of the electrolysis with the cathode comprising the first expand metal, the method of recovering the performance of the cathode constituting the ion exchange membrane system electrolytic cell is used by attaching the second expand metal to be in close contact with the first expand metal.
