の出願を行つた（実願昭54−148117）。 In a finger-type electrolytic cell that is partitioned into an anode and a cathode by a cation exchange membrane, the present inventors placed a blanket on the bottom plate of the anode chamber, the blanket surface of which is made of a chlorine-resistant material that does not contain polyvalent metal ions. An application was filed for an electrolytic cell for alkali metal chlorides (Utility Application No. 54-148117).

について研究の結果本考案に到達した。 In electrolytic cells, a blanket is placed on the surface of the bottom plate for insulation and protection of the bottom plate. Conventionally, a blanket is made of a rubber sheet or the like, and polyvalent metal ions such as calcium and magnesium contained in the rubber are dissolved during electrolysis. In diaphragm electrolysis, polyvalent metal ions do not cause any problems even if they adhere to the membrane, but
We found that the adhesion of these metal ions to the ion exchange membrane would cause problems such as high voltage and operational problems, and filed the above utility model for a blanket made of a chlorine-resistant material that does not contain these polyvalent metal ions. However, when mounting an anode on such a blanket that has a chlorine-resistant surface that does not contain polyvalent metal ions, there is often a problem that the electrolyte is prone to leak even when the anode flange is tightened. As a result of research into an electrolytic cell that does not elute polyvalent metal ions or leak electrolyte, we arrived at the present invention.

The contents include an alkali metal chloride electrolytic cell in which an elastic body having rubber elasticity is provided on the surface of the blanket around the hole and is tightened with a collar for attaching the anode.

Blankets made of corrosion-resistant metals such as , titanium, etc. are used. Alternatively, a sheet of such material may be provided on the surface of an ordinary rubber blanket, and its thickness may vary.
