PROBLEM TO BE SOLVED: To provide an electrolytic bath for ion exchange membrane in which an electrode including two layers of expanded metals is arranged on an electrode surface and a method of manufacturing the electrolytic bath for the ion exchange membrane. SOLUTION: In the cathode chamber of the electrolytic bath 1 for ion exchange membrane method, divided into an anode chamber and the cathode chamber with an ion exchange membrane 4, a cathode 8 is provided on a first expanded metal 8A surface such that the surface of a second expanded metal 8B having a step width, a minor axis and a major axis smaller than the half of those of the first expanded metal 8A faces the ion exchange film. The cathode 8 is attached to be connected to a cathode support 7 connected to a cathode chamber can body 3. In the electrolytic bath 1 for ion exchange membrane method, a plane formed by connecting the surface of the cathode intersecting a part formed by vertically projecting the cathode support 7 on the cathode surface except for the connection part with the cathode 8 is expressed as a reference plane, and the longest vertical distance from the reference plane to the cathode 8 is 0.05-0.3 mm. There is also provided a method of manufacturing the electrolytic bath for ion exchange membrane method. COPYRIGHT: (C)2010,JPO&INPIT |
