<p>PURPOSE:To prevent leak current with the shortend length of liquid feed and discharge pipes by connecting non-conductive insertion pipes to the liquid feed and discharge pipes in a unit electrolytic cell and forming part of electric resistances between electrolytic cell and headers in the insertion pipes. CONSTITUTION:Non-conductive insertion pipes 7 made of a polytetrafluoroethylene resin or the like connected to liquid feed and discharge pipes 4 are provided in a unit electrolytic cell 1. Thereby, part of the electric resistance between the cell 1 and a header 3 for liquid feeding or a header 2 for liquid discharging are formed with the pipes 7. By this constitution, the length of the pipes 4 is shortened by as much as it corresponds to the electric resistances formed in the pipes 7 and leak current is prevented.</p> |
