ABSTRACT:
A bipolar zero-gap electrolytic cell comprising an anode comprising an anode substrate constituted of a titanium expanded metal or titanium metal net of 25 to 70% opening ratio, which anode after coating the substrate with a catalyst has a surface of 5 to 50 μm unevenness difference maximum and has a thickness of 0.7 to 2.0 mm. In this electrolytic cell, the possibility of breakage of ion exchange membrane is low, and the anolyte and catholyte have a concentration distribution falling within given range. With this electrolytic cell, stable electrolysis can be performed for a prolonged period of time with less variation of cell internal pressure.
