製作コストが低減される。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an assembly of a frame spacer and a porous electrode, and more particularly to a liquid-flow type porous electrode used when electrolyzing a solute or a dispersoid in a solution or suspension. Regarding the assembly of quality electrode and frame spacer In electrolysis where the electrolyte is a solute in a solution or a dispersoid in a suspension or emulsion, there is a limit to increasing the concentration due to restrictions such as solubility. There is. Therefore, special measures are required to trap the electrolyte in the electrode. In other words, in an electrolytic cell that electrolyzes water to generate gas, water, which is the substance to be electrolyzed, is always present on the surface of the electrode, and the diffusion process of the substance to be electrolyzed is not given much consideration during the electrolytic reaction process. However, when electrolyzing a substance to be electrolyzed whose concentration is limited due to constraints such as solubility, the current density may not be sufficient unless an electrolytic cell is used that is designed so that the electrodes can efficiently capture the substance to be electrolyzed. Electrolysis cannot be performed. If the current density can be increased, the electrode area can be reduced, and the manufacturing cost of the electrolytic cell can be reduced.

び特公昭54−26231号）。 In order to electrolyze the substance to be electrolyzed with a large capture rate, that is, with a high current density, electrolytic cells with porous liquid-flowing electrodes have recently been developed (for example, Japanese Patent Publication No. 19228-1989, -26230, and Special Publication No. 54-26231).

いても全く同様に起り得る。 The structure of such an electrolytic cell generally consists of four elements: a substrate (electrode plate or bipolar partition plate), a frame-shaped spacer, a porous liquid-flowing electrode simply loaded into the frame, and a diaphragm. It has more components than conventional electrolyzers for water electrolysis (eg, US Pat. No. 3,135,673) because of the provision of porous liquid-flowing electrodes. These new types of electrolytic cells therefore pose new challenges, such as simplifying the structure and lowering production costs, but in addition to this, liquid flows between the porous electrode and the spacer, causing the electrolyte to become unbalanced. It has been found that problems such as a reduction in the capture rate, the movement of the porous electrode from its original position, or the fact that when carbon cloth is used as the porous electrode, the carbon fibers loosen and escape occur. These problems can occur in exactly the same way in batteries, which are in opposite positions with respect to electrolytic cells and electrode reactions.

等に欠点がある。 Conventionally, in order to solve the above problem, a porous electrode was constructed by coating or impregnating a part of the porous electrode with a resin and using this part as a spacer (for example, in
56-162882), but in this case, if an expensive material is used for the porous electrode, the spacer part is generally not used as an electrode, which increases the production cost, and the problem is that the porous electrode When it is desired to provide a difference in thickness between the spacers, there are drawbacks such as the manufacturing method becomes complicated and technically difficult, and the resin suitable for the coating or impregnation is limited.

Spacers with shapes and functions are widely applicable. In addition, as the liquid-flowing porous electrode loaded in the frame of the frame-shaped spacer, it is preferable to use a layer of electron-conductive porous material or fine-mesh material, but non-electron-conducting A porous material in which a conductive material is coated with an electronically conductive material can also be used.
Specifically, carbon cloth, carbon paper, other porous carbon, metal mesh, porous sintered metal, other porous metal, or general vegetable fiber. Preferred examples include asbestos and asbestos plated with metal non-electrolytically, and composite materials made by laminating the above-mentioned materials. In addition to the above, an aggregate of carbon particles such as activated carbon or metal particles can also be used as a preferable porous electrode. On the other hand, the resin filling the contact gap between the frame spacer and the porous electrode may be either natural or synthetic as long as it has excellent corrosion resistance, heat resistance, mechanical strength, adhesive properties, etc. .

要もないなどの利点がある。 According to the porous electrode of the present invention, two effects can be simultaneously achieved: the effect of integrating the spacer and the porous electrode, and the ability to select a preferable combination of these materials independently. In other words, regarding the former, even when using a high-density porous electrode that has a high capture rate of the electrolyte and therefore a large pressure loss during liquid flow, it is possible to prevent drifting between the spacer and the porous electrode. Therefore, equal distribution of liquid within the cell is promoted and good electrolysis is performed. Further, since the spacer and the porous electrode are integrated, the electrolytic cell can be easily assembled, and the labor and manufacturing costs can be reduced. on the other hand,
Regarding the latter, the hardness, thickness, and durability of the spacer and porous electrode can be freely selected depending on the purpose, and the spacer part can be made of inexpensive resin, and is generally expensive. It has the advantage that there is no need to use excessive porous electrodes.
