<P>PROBLEM TO BE SOLVED: To provide an ion exchange membrane method type electrolytic cell which has small electric energy loss, prevents breakage of an ion exchange membrane for a long period of time, and suppresses a time-varying rise of voltage and time change in current efficiency. <P>SOLUTION: The ion exchange membrane method type electrolytic cell is configured in such a way that a coil cushion material 4 is interposed between a conductive plate 2 and a cathode 3 of a cathode chamber, and the cathode comes in contact with an ion exchange membrane 5. The conductive plate is formed of an imperforate plate, and the coil cushion material is installed in such a manner that the coil expanding/contracting direction of the coil cushion material is matched with the longitudinal direction of the ion exchange membrane method type electrolytic cell. <P>COPYRIGHT: (C)2012,JPO&INPIT |
