The casing 58 includes a flange 58a formed at an upper end portion, a bottom portion 58d having a boss portion 58b for supporting the anode and a plurality of through holes 58c. A cylindrical cathode 60 made of stainless steel is engaged in the casing 58, and a cup-shaped insulated electrode holder 62 is fitted to the upper end inside the cathode. Casing 58 and cathode 60

The electrode holder 62 includes a boss 62a for supporting the anode 64 concentrically with the cathode 60, and a cathode terminal opening 62b. In the opening 62b, a lead wire 66 connected to the upper portion of the cathode 60 by solder or the like extends. On the other hand, the upper end of the anode 64 protrudes from the upper end of the boss 62 a, and the terminal 70 of the lead wire 69 is fixed by the nut 68.

In the electrode assembly 52, the anode 6
A porous anode diaphragm 80 is arranged on 4, and a cylindrical cathode chamber 82 is formed between the cathode 60 and the anode 64. The cathode chamber 82 is filled with a cathode filler 88 made of a mixture of a granular conductor 84 and a granular insulator 86, and the mixing ratio is in the range of 1: 1.5 to 1.5: 1 in volume ratio. Determined. The granular conductor 84 is selected from 1 to 3 mm graphite particles and carbon particles, and the granular insulator 86 is selected from 1 to 3 mm glass beads, plastic pellets or ceramic balls. Here, if only the granular conductor is filled in the cathode chamber 82, the granular conductor on the side closer to the electrode is polarized extremely higher than the granular conductor in the center, and as a result, the granular conductor on the side closer to the electrode becomes The current density becomes high only on the body and becomes intense, which does not mean that the electrode area is significantly increased. Therefore, in the present invention, by blending the granular insulator with the granular conductor in the above ratio, the length of the series of the granular conductor from the cathode is made longer, and the longer the distance in the direction of the anode, the higher the electrical resistance value is. In consideration of this, the electrochemical reaction proceeds almost uniformly on all the granular conductors, and the electrode surface area, that is, the electrolytic reaction field is remarkably enlarged. If the mixing ratio of the granular insulator is increased so that the mutual contact between the granular conductors is completely cut off, a bipolar phenomenon is induced on the granular conductor, and the electrolytic efficiency is reduced. is there.
