A multi-pole type in which a large number of polar electrolytic cell units are laminated via a cation exchange membrane, and an end electrode chamber unit having either an anode or a cathode on one side is laminated at both ends and fixed by a hydraulic press or the like. A large number of anode chamber units and cathode chamber units having the same electrode are laminated on both sides of a filter press type electrolytic cell and a frame-shaped electrode chamber frame via a cation exchange membrane, and an anode or a cathode is provided on one side at both ends. There is a monopolar filter press type electrolytic cell in which electrode chamber units are laminated. The electrode chamber unit of the monopolar electrolytic cell reinforces the frame-shaped electrode chamber frame and has downcomers and ribs that act to promote the circulation of the electrolyte, and electrodes are attached to these ribs, etc. Does not have a partition for separating the electrolyte.

なかった。[0004] On the other hand, a bipolar cell unit is provided with a partition for separating an anode chamber and a cathode chamber and for transmitting an electrolytic current. An anode and a cathode are attached to partition walls separating the anode chamber and the cathode chamber, respectively. One of the anode chamber and the cathode chamber is in an oxidizing environment and the other is in a reducing environment, depending on the electrolytic reaction of interest. Particularly in salt electrolysis, which is an electrolysis method using a typical ion exchange membrane, chlorine is generated at the anode, and high concentration sodium hydroxide and hydrogen are generated at the cathode. Titanium, tantalum,
A thin film forming metal such as zirconium or an alloy thereof is used. Further, in the atmosphere of the cathode chamber, titanium absorbs hydrogen and becomes brittle, so that titanium having high corrosion resistance cannot be used in the cathode chamber. For this reason, iron-based metals such as iron, nickel, and stainless steel or alloys thereof are used in the cathode chamber. Each electrode chamber is formed by a partition made of a metal material, and the two can be joined to form an electrical connection.However, titanium on the anode chamber side and iron, nickel, stainless steel, etc. on the cathode chamber side are directly welded. When joining was attempted, a joint having practical strength could not be obtained because titanium and an iron-based metal on the cathode chamber side formed an intermetallic compound.

For example, Japanese Patent Publication No. 53-5880 discloses that a member on the anode chamber side and a member on the cathode chamber side are connected by a bolt penetrating a partition wall of a synthetic resin material.

JP-B-56-36231 uses a composite material in which titanium and iron are joined together with copper interposed therebetween, and the titanium of the composite material is welded to the titanium of the anode-side partition wall of the bipolar electrolytic cell unit. Similarly, the composite material iron and the cathode-side iron-based metal partition are joined by welding.

た。There are various types of partition walls of a bipolar electrolytic cell. In any electrolytic cell, a rib is connected to the partition wall, and an electrode is attached to the rib by welding or the like. Although it is performed, a voltage drop due to the ribs is inevitable. In addition, a special method had to be used to join the metal on the cathode side and the metal on the anode side.

Polar Electrolyzer for Japanese Patent Application Hei 2-4
No. 5855. In an electrolytic cell with a large electrode area, such as electrolysis by the ion-exchange membrane method of salt, if the current distribution in the electrode chamber becomes uneven, partial consumption of the electrode proceeds or the ion-exchange membrane becomes partially Unfavorable phenomena occur in the performance of the electrolytic cell such as deterioration to
Attachment positions of the electrode and the current collecting member are devised so that the current flow paths of the anode, the partition, the cathode, and the anode are substantially equal, and the current distribution in the electrode chamber is made uniform.

も十分な効果が得られない。In addition, the electrolytic cell has a structure in which the current distribution is uniform, and the distribution of the concentration and temperature of the electrolytic solution in the electrode chamber is reduced. In order to reduce the concentration and temperature distribution of the electrolyte, the circulation speed or circulation amount of the electrolyte supplied from the outside to the electrode chamber and taken out is increased, but the circulation amount is increased. To do so, a large circulation device is required,
A sufficient effect cannot always be obtained in terms of making the concentration or temperature of the electrolyte uniform.

An electrolytic cell frame 32 is provided below the electrolytic cell unit 31. The partition wall 34 to be formed is attached to the electrolytic cell frame. The electrode 35 is connected to the partition. Since the lower part of the electrode chamber is constituted by the rigid electrolytic cell frame 32 as described above, it is structurally difficult to provide a means for uniformly dispersing the electrolytic solution.

However, since the anode side and the cathode side partition can be formed in the same shape, the anode side and the cathode side are formed. It is only necessary to prepare the same press die. In addition, by pressing each of the materials of the anode side partition and the cathode side partition one by one in a state of being laminated, irregularities can be formed on both partitions and the both partitions can be integrated at the same time. It is possible to

る電解槽の製造方法。3. A method for producing an electrolytic cell having a partition plate in which an anode-side partition and a cathode-side partition of the electrolytic cell unit are formed with projections and depressions to be fitted to each other, and both partition walls are overlapped and integrated. Wherein the lower part of the partition is bent to form an electrolyte dispersion supply chamber with a member integral with the partition plate.
