Description

  The present invention relates to an electrochemical device.

  Conventionally, as an electrochemical device, a unipolar generator is rotated by wind power to generate electricity, and the electrolytic solution of the electrolytic device installed separately from the unipolar generator is electrolyzed using the electric power to generate hydrogen gas and oxygen gas. Is known (for example, Patent Document 1). As shown in FIG. 3, the monopolar generator generates an electromotive force between the center side and the outer peripheral side of the rotating plate by rotating a rotating plate made of a non-magnetic conductor so as to cross the magnetic flux of the magnet. Is. In addition to rotating the rotating plate with the magnet stationary, this monopolar generator generates electromotive force even when the magnet and the rotating plate are rotated at the same time, but when the rotating plate is stationary and the magnet is rotated. No electromotive force is generated. In order to extract the electromotive force of the monopolar generator, a brush is brought into contact with each of the center side and the outer peripheral side of the rotating plate, and the electromotive force is taken out through each brush. The contact between the brush and the rotating plate is a sliding contact and wears down. In order to solve the problem of wear deterioration, in Patent Document 2, a liquid metal is disposed in an annular groove-shaped liquid reservoir provided on a rotating plate, and an electromotive force is taken out by a contactor that contacts the liquid metal. doing.

U.S. Pat. No. 4,184,084 JP-A-5-244758

  However, in patent document 1, since the single pole generator and the electrolysis apparatus were installed separately, there existed a problem that it was not suitable for size reduction. Moreover, in patent document 2, although the liquid metal is utilized instead of the sliding contact of a monopolar generator, since only mercury was considered as a liquid metal, there existed a problem that it was highly toxic with respect to a living body. .

  The present invention has been made to solve such problems, and has as its main object to provide an electrochemical device that eliminates sliding contacts and is suitable for miniaturization.

The first electrochemical device of the present invention comprises:

It is equipped with.

  In this electrochemical device, a cell container storing ion-containing water is rotated together with a rotating shaft in a state where a magnetic field penetrating the bottom surface of the cell container is generated. Then, an electromotive force is generated between the central side and the outer peripheral side of the ion-containing water (functioning as a nonmagnetic conductor disk) by the principle of the monopolar generator. The 1st cylindrical electrode is arrange | positioned at the center side of ion-containing water, and the 2nd cylindrical electrode is arrange | positioned at the outer peripheral side. Therefore, a potential difference is generated between the first cylindrical electrode and the second cylindrical electrode, and water electrolysis proceeds. As a result, hydrogen gas is generated at one of the first and second cylindrical electrodes, and oxygen gas is generated at the other. A space between the first cylindrical electrode and the second cylindrical electrode is divided into an inner peripheral space and an outer peripheral space by a cylindrical partition member. The ion-containing water is divided into a first cylindrical electrode side and a second cylindrical electrode side by a cylindrical diaphragm. Therefore, the gas generated in the first cylindrical electrode is taken out of the housing through the inner circumferential space and the inner circumferential gas passage. Further, the gas generated in the second cylindrical electrode is taken out of the housing through the outer peripheral side space and the outer peripheral side gas passage. Here, the magnet and cell container constituting the monopolar generator, the cell container constituting the electrolysis apparatus, and the first and second cylindrical electrodes are also housed in one housing. Therefore, it is suitable for downsizing. Moreover, as for the 1st and 2nd cylindrical electrode, as for all, one end is immersed in the ion containing water in a cell container in the non-contact state, and the other end is being fixed to the housing. For this reason, even if the cell container rotates with the rotating shaft, the life of the apparatus is extended because there is no sliding contact that deteriorates wear.

  The magnet may be configured to rotate with the cell container, or may be configured not to rotate with the cell container.

  In the first electrochemical device of the present invention, the magnet may be a donut-shaped magnet disposed on the bottom surface side of the cell container, and the rotating shaft may be inserted through a central hole. If such a tonut-shaped magnet is employed, it is easy to generate a magnetic field that penetrates the bottom surface of the cell container.

  In the first electrochemical device of the present invention, the rotating shaft may be connected to a propeller shaft of a wind turbine or a water turbine. In this way, renewable energy such as wind power or hydraulic power can be converted into hydrogen gas or oxygen gas.

An outer peripheral side gas passage for taking out gas in the outer peripheral side space out of the housing;
It is equipped with.

  In this electrochemical device, the disk is rotated together with the rotating shaft in a state where a magnetic field penetrating the disk made of nonmagnetic conductor is generated. Then, an electromotive force is generated between the center side and the outer peripheral side of the disk due to the principle of the monopolar generator. A first cylindrical electrode is fixed to the center side of the disk, and a second cylindrical electrode is fixed to the outer peripheral side. Therefore, a potential difference is generated between the first cylindrical electrode and the second cylindrical electrode. Moreover, the 1st and 2nd cylindrical electrode is immersed in the ion containing water in a cell container in the non-contact state in a cell container. Therefore, electrolysis of water proceeds, hydrogen gas is generated on one of the first and second cylindrical electrodes, and oxygen gas is generated on the other. A space between the first cylindrical electrode and the second cylindrical electrode is divided into an inner peripheral space and an outer peripheral space by a cylindrical partition member. The ion-containing water is divided into a first cylindrical electrode side and a second cylindrical electrode side by a cylindrical diaphragm. Therefore, the gas generated in the inner peripheral space is taken out of the housing through the inner peripheral gas passage. The gas generated in the outer peripheral space is taken out of the housing through the outer peripheral gas passage. Here, the magnet and the disk constituting the monopolar generator, the cell container constituting the electrolysis apparatus, and the first and second cylindrical electrodes are also accommodated in one housing. Therefore, it is suitable for downsizing. Moreover, as for the 1st and 2nd cylindrical electrode, as for all, one end is immersed in the ion containing water in a cell container in the non-contact state, and the other end is being fixed to the disk. For this reason, even if the disk rotates together with the rotating shaft, the life of the apparatus is extended because there is no sliding contact that deteriorates wear.

  The magnet may be configured to rotate with the disk, or may be configured not to rotate with the disk. Moreover, it is preferable that the cell container is configured not to rotate together with the disk.

  In the second electrochemical device of the present invention, the magnet may be a donut-shaped magnet facing the disk, and the rotating shaft may be inserted through a central hole. If such a tonut-shaped magnet is employed, it is easy to generate a magnetic field that penetrates the disk.

  In the second electrochemical device of the present invention, the rotating shaft may be connected to a propeller shaft of a wind turbine or a water turbine. In this way, renewable energy such as wind power or hydraulic power can be converted into hydrogen gas or oxygen gas.

Side gas passages 33 and 34 are provided.

  The housing 12 is a hollow cylinder having a circular upper surface and lower surface and a cylindrical side surface. The housing 12 rotatably supports a rotating shaft 14 that passes through the upper surface and the lower surface. The housing 12 is made of a nonmagnetic insulating material such as vinyl chloride resin. The rotating shaft 14 is connected to a propeller shaft 40 of the windmill.

  The cell container 16 is a bottomed cylindrical container and is integrated with the rotating shaft 14. The cell container 16 can store the ion-containing water W. Examples of the ion-containing water W include electrolytic solutions such as a sodium hydroxide aqueous solution and a sulfuric acid aqueous solution. The conductivity of the ion-containing water W is adjusted. The cell container 16 is made of a nonmagnetic insulating material such as vinyl chloride resin. The cell container 16 is supplied and discharged with ion-containing water W via a water supply / discharge path (not shown) connecting the outside of the housing 12 and the inside of the cell container 16.

  The magnet 18 is a donut-shaped magnet, and is inserted through the central hole 18a in a non-contact state. Therefore, even if the rotating shaft 14 rotates, the magnet 18 does not rotate. The magnet 18 generates a magnetic field that penetrates the bottom surface of the cell container 16. Such a magnet 18 may be a neodymium magnet or a ferrite magnet, or may be a superconducting magnet.

  The first cylindrical electrode 21 is formed coaxially with the rotating shaft 14. The lower end 21 a of the first cylindrical electrode 21 is immersed in the ion-containing water W in the cell container 16 without being in contact with the cell container 16. An upper end 21 b of the first cylindrical electrode 21 is fixed to the ceiling back surface of the housing 12. The rotation shaft 14 is inserted into the central hole of the first cylindrical electrode 21 in a non-contact state.

  The second cylindrical electrode 22 has a larger diameter than the first cylindrical electrode 21 and is formed coaxially with the rotating shaft 14. The lower end 22 a of the second cylindrical electrode 22 is immersed in the ion-containing water W in the cell container 16 without being in contact with the cell container 16. The upper end 22 b of the second cylindrical electrode 22 is fixed to the ceiling back surface of the housing 12. The first cylindrical electrode 21 and the second cylindrical electrode 22 are electrically connected by a copper wire 24 at a position spaced upward from the cell container 16 (here, a position close to the back surface of the ceiling of the housing 12). Therefore, the copper wire 24 is not easily affected by the magnet 18. The copper wire 24 penetrates the cylindrical partition member 26.

  The cylindrical partition member 26 has an intermediate diameter between the first cylindrical electrode 21 and the second cylindrical electrode 22 and is formed coaxially with the rotary shaft 14. An upper end 26 b of the cylindrical partition member 26 is fixed to the ceiling back surface of the housing 12. The lower end 26 a of the cylindrical partition member 26 is located slightly above the cell container 16. The cylindrical partition member 26 divides the space between the first cylindrical electrode 21 and the second cylindrical electrode 22 into an inner peripheral space 31 and an outer peripheral space 32. The cylindrical partition member 26 is made of a nonmagnetic insulating material such as vinyl chloride resin.

  The cylindrical diaphragm 28 is formed coaxially and with the same diameter as the cylindrical partition member 26. The cylindrical diaphragm 28 divides the ion-containing water W in the cell container 16 into a first cylindrical electrode 21 side and a second cylindrical electrode 22 side. A lower end 28 a of the cylindrical diaphragm 28 is fixed to the cell container 16. The upper end 28b of the cylindrical diaphragm 28 is opposed to the lower end 26a of the cylindrical partition member 26 with a small gap. The cylindrical diaphragm 28 is made of, for example, a polymer porous membrane (ion exchange membrane). The minute interval can maintain the upper end 28b of the cylindrical diaphragm 28 and the lower end 26a of the cylindrical partition member 26 in a non-contact state, and almost no gas flows between the inner circumferential side space 31 and the outer circumferential side space 32. Not set to a size.

  The inner peripheral side gas passage 33 is a passage for taking out the gas in the inner peripheral side space 31 to the outside of the housing 12. The inner peripheral gas passage 33 reaches a hole 33 a provided in the ceiling of the housing 12 through the inner peripheral space 31. The outer peripheral side gas passage 34 is a passage for taking out the gas in the outer peripheral side space 32 to the outside of the housing 12. The outer peripheral gas passage 34 reaches a hole 34 a provided in the ceiling of the housing 12 through the outer peripheral space 32.

  Next, a usage example of the electrochemical device 10 will be described. Here, a case where hydrogen gas and oxygen gas are generated by electrolyzing water using electric power generated using the principle of a monopolar generator will be described. First, a magnet 18 generates a magnetic field that penetrates the bottom surface of the cell container 16. In this state, the cell container 16 integrated with the rotating shaft 14 is rotated by rotating the rotating shaft 14 with the windmill. Then, due to the principle of the unipolar generator, the ions of the ion-containing water W (which functions as a non-magnetic conductor disk) in the cell container 16 are subjected to force and are generated between the center side and the outer peripheral side of the ion-containing water W. Electric power is generated. The first cylindrical electrode 21 is disposed on the center side of the ion-containing water W, and the second cylindrical electrode 22 is disposed on the outer peripheral side. Therefore, a potential difference is generated between the first cylindrical electrode 21 and the second cylindrical electrode 22, and water electrolysis proceeds. As a result, hydrogen gas is generated on one of the first and second cylindrical electrodes 21 and 22, and oxygen gas is generated on the other. A space between the first cylindrical electrode 21 and the second cylindrical electrode 22 is divided into an inner peripheral space 31 and an outer peripheral space 32 by a cylindrical partition member 26. Further, the ion-containing water W is divided into a first cylindrical electrode 21 side and a second cylindrical electrode 22 side by a cylindrical diaphragm 28. Therefore, the gas generated in the first cylindrical electrode 21 is taken out of the housing 12 through the inner peripheral side gas passage 33. The gas generated in the second cylindrical electrode 22 is taken out of the housing 12 through the outer peripheral gas passage 34. Whether the central side of the ion-containing water W is a positive pole and the outer peripheral side is a negative pole, or whether the central side of the ion-containing water W is a negative pole and the outer peripheral side is a positive pole is determined by the rotation direction of the rotary shaft 14.

  According to the electrochemical apparatus 10 described above, the ion-containing water W in the cell container 16 constituting the electrolysis apparatus, the magnet 18 constituting the monopolar generator, and the ion-containing water W in the cell container 16 are also the first and The second cylindrical electrodes 21 and 22 are also accommodated in one housing 12. Therefore, it is suitable for downsizing. The first and second cylindrical electrodes 21 and 22 are both immersed in the ion-containing water W in the cell container 16 with the lower ends 21a and 22a being in non-contact with the cell container 16, and the upper ends 21b and 22b are It is fixed to the housing 12. For this reason, even if the cell container 16 rotates together with the rotary shaft 14, there is no sliding contact that deteriorates wear, so that the life of the apparatus is extended.

  Further, since a donut-shaped magnet is employed as the magnet 18, it is easy to generate a magnetic field that penetrates the bottom surface of the cell container 16.

  Furthermore, since the rotating shaft 14 is connected to the propeller shaft 40 of the windmill, the renewable energy can be converted into hydrogen gas or oxygen gas.
