である。(Prior art and its problems) A filter press type electrolytic cell consists of an anode chamber frame that houses an anode therein and a cathode chamber frame that houses a cathode therein (both of which are also collectively referred to as electrode chamber frames). It consists of a basic structure (unit cell) that faces each other via a cation exchange membrane. In this case, one anode chamber and one cathode chamber are joined via a partition, and the anode and cathode in each chamber are electrically connected via conductive ribs, and the anode chamber There is a monopolar structure in which a cathode chamber and a cathode chamber are formed independently. In either structure, a large number of these electrodes are superimposed and fastened together to form a single electrolytic cell. Further, the electrodes used in such electrolytic cells are generally porous electrodes having a structure that allows gas generated on the electrode surface of the current-carrying part to be easily guided behind the electrode.

イルタープレス型電解槽が提案されている。 In recent years, attempts have been made to reduce the distance between the ion exchange membrane and the electrodes as much as possible to reduce the electrolytic (cell) voltage due to solution resistance, in order to increase the electrolytic efficiency in the filter press type electrolytic cell with the above structure. There is. For example, a porous electrode with a smooth surface is used, and the conductive ribs that support the porous anode and/or porous cathode sandwiching the cation exchange membrane are made into a spring structure, and the mechanical pressure of the conductive ribs creates porous holes in the cation exchange membrane. A filter press type electrolytic cell has been proposed in which a porous anode and a porous cathode are brought into close contact with each other.

When electrolysis is carried out using salt water (simply referred to as salt water), a large amount of water blister occurs on the cathode side surface of the cation exchange membrane, which is located in close contact with the joint between the porous anode and the conductive ribs, and then it is damaged. A phenomenon occurs in which catholyte is mixed into the anode chamber from the damaged part, causing a decrease in current efficiency, and the cation exchange membrane is eventually forced to be replaced, making long-term continuous operation difficult.

ルカリ金属塩水溶液の電解槽である。(Means for Solving the Problem) In order to solve the above problem, the inventors of the present invention first conducted an intensive study on the causes of the above phenomenon.
As a result, in a filter press type electrolytic cell that has a structure in which a porous anode and a porous cathode are brought into close contact with a cation exchange membrane by mechanical pressing force as described above, the pores of the porous anode are completely blocked by the conductive ribs. It has been found that the above phenomenon occurs when the structure is bonded in a state where That is, in such a case, the contact area between the cation exchange membrane and the anode surface located at the joint between the porous anode and the conductive ribs,
At the beginning of electrolysis, salt water is present, but after that, electrolysis continues without a supply of salt water, so as the energization time elapses, the salt concentration decreases, and the cathode of the cation exchange membrane It is assumed that blisters will form on the sides. Therefore, based on the above knowledge, the present inventors found that the desired problem could be solved by specifying the structure of the joint between the porous anode and the conductive rib as shown below, and developed the present invention. I have come to propose this. That is, the present invention provides a filter press type electrolytic cell having a structure in which a porous anode is closely attached to one side of a cation exchange membrane and a porous cathode is attached to the other side, in which the pores of the porous anode are formed by conductive ribs. This is an electrolytic cell for an aqueous alkali metal salt solution, characterized in that it has a structure in which conductive ribs are joined in an unobstructed state.

That is, FIG. 1 shows a filter press type electrolytic cell having a structure in which the conductive ribs 3 supporting the porous cathode 2 have a spring structure, and the cation exchange membrane 4 is in close contact with the porous anode 5 and the porous cathode 2. It is. In FIG. 1, 6 is a conductive rib, and 7 is a gasket. Generally, the conductive rib 6 is joined to the back surface of the porous anode 5 (the surface opposite to the cation exchange membrane 4) by means such as spot welding.

構造であれば特に制限されるものではない。 In such an electrolytic cell, the present invention has a porous anode 5.
The biggest feature is that the joint 8 between the conductive rib 6 and the conductive rib 6 has a specific structure. That is, FIG. 2 shows the porous anode 5 and conductive ribs 6 of the cation exchange membrane 4 which has blistered on the cathode side surface due to electrolysis and has been damaged.
FIG. 2 is a schematic diagram (showing a partial plan view and a side view) of a joint section 8 of FIG. According to the electrolytic cell having such a structure, since the holes 9 of the porous anode 5 are completely closed by the conductive ribs 6, the contact portion 10 between the anode 5 and the cation exchange membrane 4 as shown in FIG. Blisters and damage occur in the shaded area. On the other hand, the electrolytic cell of the present invention has a structure in which the holes 9 of the porous anode 5 are not blocked by the conductive ribs 6, so that the salt concentration does not locally decrease in that part, and as described above. Does not cause any problems. The holes 9 of the porous anode are the conductive ribs 6
For example, as shown in FIG. 3, the shape of the hole 9 of the porous anode is made elliptical so that the size of the hole 9 is larger than the width of the conductive rib 6, or As shown in FIG. 4, a groove 11 is cut between the hole 9 and the hole 9', etc.
There are no particular limitations as long as the structure is such that salt water is constantly supplied to the contact portion 10 shown in FIG.

There is no particular restriction on the structure as long as the porous cathode is brought into close contact with the other surface by mechanical means.
In such a battery case, the pressing force between the anode and the membrane is particularly large and the adhesion is strong, so the structure of the present invention is extremely effective. Although FIG. 1 shows a bipolar filter press type electrolytic cell, for example, a monopolar filter press type electrolytic cell may be used. Furthermore, as shown in Fig. 1, the present invention is not limited to the filter press type electrolytic cell in which the conductive rib 3 connected to the porous cathode 2 has a spring structure, but also the known filter press type electrolytic cell in which the cation exchange membrane is in close contact with the porous electrode. It is also suitably applied. In addition, the pressing pressure when bringing the porous anode and porous cathode into close contact with the cation exchange membrane should be 200 mmAq or more when the gas pressure difference (PK-PA) between the anode chamber and the cathode chamber is 30 mmAq or more.
mmAq or more, mechanical pressing pressure 2g/cm 2 or more,
Particularly preferred is 20 g/cm 2 or more.
