発生させる技術が実用化されている。2. Description of the Related Art Conventionally, a voltage is applied (that is, electrolysis) to water in an electrolytic cell,
A technique for generating acidic ionized water on the anode side and alkaline ionized water on the cathode side has been put into practical use.

位（ＯＲＰ）が上昇する。In this case, as shown in FIG. 6, on the anode side, the oxidation reaction of 2H 2 O → O 2 + 4H + + 4e − (1) proceeds to generate oxygen gas on the surface of the anode electrode. , Hydrogen ions are accumulated, and the redox potential (ORP) rises.

位が低下する。On the other hand, on the cathode side, a reduction reaction of 4H 2 O + 4e − → 2H 2 + 4OH − (2) progresses to generate hydrogen gas on the surface of the cathode electrode and also to accumulate hydroxide ions, resulting in redox. The potential drops.

問題があった。In this case, as a result, high oxidation-reduction potential water is generated on the anode side and low oxidation-reduction potential water is generated on the cathode side, but liquid turbulence may occur due to vibration in the electrolytic cell, In this case, there is a problem that the high oxidation-reduction potential water and the low oxidation-reduction potential water that are generated are mixed and the recovery efficiency is reduced.

されている（例えば、特開平４−３７１２９１号及び実
公平４−５１９１７号等参照）。In order to solve this problem, conventionally, in order to prevent the mixing of the high oxidation-reduction potential water and the low oxidation-reduction potential water, while ensuring the electrical conductivity, between the anode and cathode of the electrolytic cell, A method of disposing a membrane having water permeability and electrolyzing it has been proposed (see, for example, JP-A-4-371291 and JP-B-4-51917).

面において水素ガスとなる。However, in the membrane having water permeability as shown in FIG. 6, since the ions diffuse through the membrane, the hydrogen ions accumulated at the anode as described above are permeable through the membrane. When it enters the electrolytic cell on the cathode side and is attracted to the cathode, the oxidation reaction of 4H + + 4e − → 2H 2 (3) proceeds, and as a result, hydrogen ions become hydrogen gas on the cathode surface.

において酸素ガスとなる。On the other hand, as described above, the hydroxide ions accumulated at the cathode enter the electrolytic cell on the anode side through the diaphragm and are attracted to the anode, and 4OH − → O 2 + 2H 2 O + 4e − The reduction reaction of (4) proceeds, and as a result, the hydroxide ions become oxygen gas on the surface of the anode.

得ることが困難となっていた。Therefore, the oxidation reaction (1) and the reduction reaction (4) proceed simultaneously on the anode side, while the reduction reaction (2) and the oxidation reaction (3) proceed simultaneously on the cathode side. . As a result, the changes in the redox potential in the electrolytic cells on both sides are slower as a whole, so that water and redox potential, which have higher redox potential, are higher than those in the electrolytic cells on the electrode sides divided by the diaphragm. It was difficult to obtain water with a low electric potential.

Then, hydroxide ions are accumulated. After that, when the charging direction is reversed, as shown in FIG. 7B, the hydrogen ions accumulated on the anode side change the electrode to the cathode, and the reaction of (3) rapidly progresses.

以下に説明する。First, using a bipolar film, as shown in FIG.
As shown in FIG. 5, electrolysis by so-called “reverse charging”, that is, the cation surface 22b side of the bipolar film 22 is the anode 1
2 side, the anion surface 22a side is arranged on the cathode 14 side to perform electrolysis, and then, as shown in FIG. 8B, so-called “positive charge” electrolysis, that is, the bipolar film 22.
The anion face 22a side of the cation face 22a
The case where the b side is arranged on the cathode 14 side and electrolysis is performed will be described below.

槽１８に水酸イオンが蓄積される。As shown in FIG. 8A, in the case of reverse charging, when the hydrogen ions generated on the anode 12 side are attracted to the cathode 14 side, the bipolar film 22 disposed between the electrodes is formed. Since the hydrogen ions are blocked by the anion surface 22a, the hydrogen ions do not flow into the cathode-side electrolytic cell 18, and the hydrogen ions are accumulated in the anode-side electrolytic cell 16. On the other hand, similarly, when the hydroxide ions generated on the cathode 14 side are attracted to the anode 12 side, the bipolar film 2 disposed between the electrodes is formed.
Since the second ion is blocked by the cation surface 22b, the hydroxide ion does not flow into the anode electrolytic cell 16 and accumulates in the cathode side electrolytic cell 18.

れる。In this case, when the water molecules penetrating the bipolar film 22 itself are ionized into hydrogen ions and hydroxide ions, the hydrogen ions pass through the cation surface 22b of the bipolar film 22 and are attracted to the cathode 14. Since the anion surface 22a of the bipolar film 22 disposed on the cathode 14 side is blocked, the reaction of the above (3) proceeds and the cathode 14
No hydrogen gas is generated on the surface. Further, in the same manner, the hydroxide ion is anion surface 22a of the bipolar film 22.
When passing through the anode 12 and attracted to the anode 12, the anode 12
Since the cation surface 22b of the bipolar film 22 disposed on the side is blocked, the reaction of (4) above does not proceed and oxygen gas is not generated on the surface of the anode 12. Therefore,
Due to the ion blocking action of the bipolar film 22, hydrogen ions are efficiently separated and accumulated in the anode side electrolytic cell 16 and hydroxide ions are efficiently accumulated in the cathode side electrolytic cell 18, respectively.

の「△」参照）。Next, when hydrogen ions and hydroxide ions are accumulated in both electrodes and then the electrolysis is carried out by positive charging with the charging directions reversed, the reaction as shown in FIG. Progresses. That is, the hydrogen ions accumulated on the anode side are changed to the cathode by the electrode, and the reaction of (3) rapidly progresses to hydrogen gas, and at the same time, the water molecules permeated into the bipolar film 22 itself are hydrogen ions. When ionized into hydroxide ions, hydrogen ions permeate the cation surface 22b of the bipolar film 22 and are attracted to the cathode 14, and the reduction reaction of (3) above proceeds to generate hydrogen gas on the surface of the cathode 14.

When the water molecules are ionized into hydrogen ions and hydroxide ions, the hydroxide ions pass through the anion surface 22a of the bipolar film 22 and are attracted to the anode 12, and the oxidation reaction of (4) above proceeds and the anode Oxygen gas is generated on the 12 surface. Therefore, as a result, the increase in the redox potential is further accelerated (see “⋄” in FIG. 4).
