Abstract: Bipolar electrolysis cell incorporates an andoe, a cathode and an anode-side cell dividers with projections. The novelty is that these projections are electrically connected with the anode. USE/ADVANTAGE - The cell is suitable for the electrolysis of industrial substances e.g. brine in the production of chlorine. The electrical resistance is minimised on the anode side, reducing electrical power requirement. Replacement of the anode is simple when the catalytic action has degraded. Repairs and maintenance are cheap and simple.

Abstract: A bipolar electrolytic cell includes an anode-side partition having protrusions on the anode side which are electrically connected to the anode through conductive members, or recesses formed by causing the anode-side partition to protrude on the cathode side. Use of this bipolar electrolytic cell enables the conductor resistance on the anode side to be small, allows the anode to be easily replaced when its activity as a catalyst has been deteriorated, and makes it possible to effect easy and economic repairs even when trouble has occurred during operation.

Abstract: PURPOSE:To broaden the fluctuation range of current density and brine concentration of an anode side by specifying the ratio of volume in the upper part of the electrolytic face of an anode chamber or the anode chamber and a cathode chamber in the electrolyzer of sodium chloride and effective electrolytic area and holding a liquid-gas mixed layer to at least the electrolytic face. CONSTITUTION:The ratio V/S of volume V in the upper part of the electrolytic face of an anode chamber 1 or the anode chamber 1 and a cathode chamber 2 in the electrolyzer of sodium chloride and effective electrolytic area S is regulated to >=0.1 (decimeter). In electrolysis of sodium chloride wherein this electrolyzer is used, a liquid-gas mixed layer 14 is maintained to at least the electrolytic face. By the above-mentioned method, even when the electrolyzer is operated at 8-20kA/m electrolytic current density, stable electrolytic voltage having the range of electrolytic voltage of + or -20mV is shown similarly to a time of 2-4kA/m current density.
