The hydrogen gas can be safely sucked by a top cover structure having a discharge port at the top.SELECTED DRAWING: Figure 1

Description

  The technology according to the present invention belongs to the field of hydrogen water and hydrogen gas generation by small capacity electrolysis for home and medical use.

In recent years, hydrogen water for health has been spotlighted as a means for reducing active oxygen generated in the body. It has also been reported that the symptoms of cerebral infarction were alleviated by inhalation of hydrogen gas.
For this reason, an electrolytic hydrogen water generator that uses the principle of water electrolysis to separate generated oxygen and hydrogen and dissolve hydrogen in water to obtain hydrogen water has been commercialized. The conventional major technical means obtained industrially by separating oxygen and hydrogen is an electrolyte membrane as shown in “Patent Document 1”. This is also structurally called a diaphragm, and separates the electrolysis space from the anode chamber and the cathode chamber to conduct ions and to conduct an electrolysis current.
If both electrodes are pressed against each other with this electrolytic membrane in between, purified water that does not flow current can be electrolyzed even as electrolytic raw water, and only hydrogen can be obtained from the cathode chamber.
Similarly, “Patent Document 2” is an example of a “pressure resistance, hermeticity, and cost-effective membrane electrode assembly” using such an electrolytic membrane. “Patent Document 3” devised to lower the equivalent resistance of this electrolytic membrane.

  Also pay attention to the prior art of “Patent Document 4”. In this case, “Isolation sheet that allows ions to pass but not electrons” is “intervened between the electrodes” to isolate only the electrodes, but separate electrode chambers are formed on both sides to isolate them. Absent. Also, “passing ions” is related to the hole diameter, and “passing electrons” is made of an insulating material, and is not related to the hole diameter. In this sheet, oxygen and hydrogen generated by electrolysis are not separated in advance, and the gas is separated after electrolysis using a difference in gas dissolution pressure. In the example diagram, a large number of electrodes are stacked with this separator sheet interposed therebetween. Electric double layer capacitors that are usually stacked use such a sheet as a separator, but the essence of this separator sheet is an insulating separator that minimizes the distance between the electrodes and prevents shorting between the electrodes. It is.

On the other hand, as the simplest electrolysis method, there is a method called diaphragmless electrolysis, in which both the anode and cathode electrodes are inserted as they are into the electrolyzed raw water. Hydrogen and oxygen are produced simultaneously from both electrodes in the same room. The inventors have confirmed through experiments that a nano-sized insulating oxide film exists on the surface of most positive electrodes, and active oxygen having a large oxidation potential due to the thickness of the film is generated. Produces ozone and sterilizing components.
Therefore, all the components generated by electrolysis are mixed in the electrolyzed water in the single chamber electrolyzed by the diaphragm. For example, if the raw water contains a very small amount of salt, the hydrogen concentration is not detected in the produced water even though hydrogen bubbles are generated in the negative electrode. Chloric acid will be detected.

  In addition, a simple device that directly sucks hydrogen gas generated by electrolyzing water is not commercially available. When an electrolytic membrane is used, not only is it expensive, but when hydrogen gas is produced in a large amount, there is a risk of explosion when it is mixed with air.

  JP 2014-1117 A   Special table 2009-513820 gazette   Special table 2014-523965 gazette   JP2015-128060A

  In the present invention, without using any prior art electrolytic membranes that are expensive and complicated in arrangement structure, water is electrolyzed, and appropriate drinking water containing no oxidative components generated on the anode side, or It is an object of the present invention to provide a simple and inexpensive electrolytic hydrogen generator that can safely obtain hydrogen gas for suction in a form that does not cause explosion.

A container, a negative electrode, a positive electrode, and a filter,
The filter is between the negative electrode and the positive electrode, and separates the container into a cathode chamber including the negative electrode and an anode chamber including the positive electrode, and the effective pore size is 1 μm to 500 μm, Electrolytic raw water containing an electrolyte is placed in at least one of the electrode chambers of the container.
The material of the filter is a cloth made of chemical fiber or cotton, paper, a metal or resin mesh, or a porous ceramic.
“Effective hole diameter” is defined herein as the maximum diameter of a sphere passing through the hole. This corresponds to “aperture” in the case of a mesh and “pore diameter” of a punching metal or a porous body.
Prior art electrolyte membranes are made of solid electrolytes and are based on ionic conduction. Even though the “pores” are not open, the charge is transferred by “conduction”, so ions do not pass through. Since the filter used in the present invention has “holes” and the ionic diameter is much smaller than 1 μm, if a hole of 1 μm or more is opened, the electrolyte present in one of the electrode chambers is contained. The ions in the electrolyte and the hydrogen ions generated at the anode are attracted by the electric field between the electrodes and pass through the hole, so that the electrolytic current continues to flow.
On the other hand, when the effective pore diameter is 500 μm or more, the positive electrode product is mixed into the cathode chamber, and therefore hydrogen as pure as possible in the cathode chamber and suitable for drinking cannot be obtained.

Next, the negative electrode uses a metal mesh having an aperture of 0.3 mm to 30 mm, or a punching metal having a hole diameter of 0.3 mm to 30 mm and an aperture ratio of 50% to 80% to allow bubbles to pass. It is preferable for supporting the filter.
In order to obtain hydrogen water efficiently, the negative electrode is in close contact with or close to each other in the order of the positive electrode, the filter, and the negative electrode from the bottom, and the horizontal or inclined angle at the bottom of the cathode chamber Is disposed within 45 °, and preferably has a bubble passage that communicates with the upper part of the container from the anode chamber below the cathode chamber. When the opening of the negative electrode is 0.3 mm or less, a portion where hydrogen bubbles generated at the negative electrode cannot move to the cathode chamber side is generated, and the bubbles grow large with time, and the flow of electrolytic current Will be disturbed. When it is 30 mm or more, it becomes difficult to closely support the thin filter. The same applies to punching metal, and the same applies to the opening ratio. If the opening ratio is smaller than 50%, hydrogen bubbles grow on the anode chamber side of the non-opening, and if it is 80% or more, punching metal passes the filter. It becomes fragile to support closely.
Hydrogen bubbles generated from the negative electrode rise upward, become microbubbles, stay in the upper part of the negative electrode, and become cloudy in the portion of the electrolyzed water in the cathode chamber. Therefore, the arrangement of the negative electrodes is preferably the above-described structure.
On the other hand, when the above structure is adopted, oxygen bubbles generated from the positive electrode stay on the positive electrode side surface of the filter close to the negative electrode. As the electrolysis time becomes longer, the bubbles obstruct the flow of the electrolysis current due to the movement of ions, so the negative electrode at the top of the filter is disposed at the bottom of the cathode chamber, but is slightly inclined from the horizontal. Preferably, when the inclination angle is greater than 45 °, the contact between the rising hydrogen bubbles and the raw water in the cathode chamber is reduced, and the efficiency of dissolving hydrogen in the raw water is lowered. If there is an inclination in this range, oxygen bubbles gathering on the lower surface of the filter move along the inclination. A bubble passage leading to the upper part of the container is arranged at the end of this movement, so that the electrolytic current can be continued.
The same effect can be obtained by arranging the negative electrode horizontally and slightly tilting the container itself.

In order to obtain only hydrogen gas exclusively, it is preferable that the cathode chamber is sealed with an upper lid on the top, and an outlet for gas extraction is provided on the upper lid. If this top cover is removable, hydrogen water can be obtained. However, in this structure, when the hydrogen gas is temporarily stored in the top cover part, the water level in the cathode chamber is lowered, and the water level in the anode chamber is lowered by that amount. The raw water overflows easily.
The structure which compensates for this fault was also devised. Hydrogen water can be obtained if the upper lid container is removed, and if the upper lid container is placed in the cathode chamber, the accumulated hydrogen gas can be obtained without overflowing the raw water. Therefore, it is preferable to dispose an upper lid container that is open at the bottom and is provided with an outlet for gas discharge at the top. As the hydrogen gas accumulates, the upper lid container moves upward and the water level does not change. When the hydrogen gas is sucked, the hydrogen gas can be safely sucked from the hydrogen outlet at the top of the upper lid container.
In order to prevent hydrogen explosion, regardless of which hydrogen gas is obtained, the air immediately below the upper lid is discharged in advance at the start of electrolysis, and the oxygen generated in the anode chamber is sequentially released to the outside air. When the anode chamber is disposed below the cathode chamber, a bubble passage for releasing oxygen into the outside air and an oxygen discharge port are provided on the anode chamber side.

According to the present invention, high-concentration microbubble hydrogen water free from the mixing of anode products can be produced at low cost, so that active oxygen accumulated in the body due to fatigue or aging can be effectively reduced and removed. I can do it. The tap water, tea, juus, and the like contain an electrolyte in advance, and the composite hydrogen water can be generated by adding the hydrogen water as it is.
Moreover, even if hydrogen water is drunk, the amount of hydrogen that is finally absorbed into the body in the intestine is estimated to be very small. However, if hydrogen gas is sucked into the lungs, it can be estimated that the amount of blood absorbed by the blood as well as oxygen is large. Moreover, even if 250 cc of hydrogen water having a hydrogen concentration of 0.8 ppm is consumed, the amount of hydrogen is about 2.2 cc. On the other hand, if this device is electrolyzed at a current of 480 mA, 3.3 cc of hydrogen is produced per minute. If this is aspirated directly into the lung, the hydrogen concentration in the blood will increase, and the effect on diseases such as aging and cerebral infarction can be expected to increase.
A small amount of hydrogen gas generated continuously can be mixed with air to remove the danger of explosion and can be safely aspirated during sleep. It is groundbreaking if it helps prevent aging diseases such as dementia.

  Cross-sectional view showing the concept of obtaining hydrogen water according to the present invention   Cross-sectional view of arrangement example of both electrodes and filter according to the present invention   FIG. 2 is a plan view of an arrangement example of both electrodes and filters according to the present invention as viewed from below.   Conceptual configuration sectional view of an embodiment for obtaining hydrogen gas according to the present invention   Conceptual configuration sectional view of another embodiment for obtaining hydrogen gas according to the present invention

The form which obtains hydrogen water by this invention using FIG. 1 is demonstrated. Reference numeral 1 denotes a container for obtaining electrolytic hydrogen water, and a filter 6 separates the container 1 from the cathode chamber 3 and the anode chamber 4. The bubble passage 12 forms part of the anode chamber 4 and is partitioned from the cathode chamber 3 by the partition 2. Bubbles of oxygen and ozone generated at the positive electrode 7 pass through the bubble passage 12 and are released to the outside air from the oxygen exhaust port 13. Here, the assembly of the electrode portion will be described with reference to FIGS.
2 is a view of the electrode portion of FIG. 1 as viewed from the left side, and FIG. 3 is a view of FIG. 2 as viewed from the bottom side. Since the filter 6 is thin and weak, the entire surface is overlapped on the negative electrode 5 made of a metal mesh, leaving the feeding portion 22, and an adhesive is attached only to the periphery to adhere to the negative electrode 5 so that both are integrated. To do. The positive electrode 6 is placed at the bottom, the filter 6 is placed on the positive electrode 6 and the negative electrode 5 is placed on the positive electrode 6 in that order. The negative electrode 5 is bonded to the cathode chamber together with the filter 6 at the periphery. Thus, the cathode chamber 5 is formed and separated from the anode chamber 4.
However, the structure and arrangement of both electrodes are not limited to the above, and the spirit of the present invention is not impaired as long as the filter 6 separates the container 1 from the cathode chamber 3 and the anode chamber 4.

The positive electrode 7 is preferably titanium coated with platinum, preferably in the form of a rod in consideration of the price and the permeability of the electrolyte between both electrodes, and the electrolytic current is reduced if the area of the negative electrode 5 is large. If the distance between the negative electrode 5 and the negative electrode 5 is small, the electrolysis efficiency can be increased. Therefore, it is preferable that both electrodes are close to each other with the filter 6 interposed therebetween.
The negative electrode feeding part 14 and the extension part of the positive electrode 7 are drawn out of the container 1 by a pressure-welding structure and an adhesive seal that do not leak water. Power is supplied through the vessel 10.
A constant current circuit 11 for keeping the electrolytic current constant is built in the controller 10 and connected to the negative electrode 5 and the positive electrode 6.

  When a small amount of an electrolyte such as sodium bicarbonate or citric acid is added from the oxygen exhaust port 13 and, for example, purified water is put into the negative electrode 5 of the container 1, the purified water slowly passes through the filter 6 due to its own water pressure, and then the anode. The chamber 7 is filled and becomes an electrolytic solution by the electrolyte. Tap water may be added instead of purified water, and tap water contains some electrolyte. Even when only tap water is added, tap water contains some electrolyte and the electrolyte is the electrode. Present in the room. When tap water has a small current, an electrolyte as described above is further added. An electrolytic solution to which an electrolyte has been added in advance may be placed in the negative electrode 5, and in this case, the hydrogen water generated in the cathode chamber 3 also includes this electrolytic solution. To drink.

    Next, the form which can attract | suck hydrogen gas continuously is demonstrated. An upper lid 20 indicated by a dotted line in FIG. 1 is attached to the upper portion of the cathode chamber 3 to seal the cathode chamber 3. Hydrogen gas can be obtained safely from the hydrogen outlet 17 if the electrolysis is started after filling the cathode chamber 3 by filling the electrolyte from the oxygen outlet. If a medical oxygen inhalation canyon is diverted and attached to the hydrogen outlet 17, a trace amount of hydrogen gas can be continuously sucked from the nostril. Hydrogen gas does not mix with air and does not accumulate in large quantities, so there is no danger of explosion and it is safe. However, if the removal of hydrogen is stopped, the raw water will overflow.

Next, an embodiment of the present invention capable of not only obtaining hydrogen water but also obtaining hydrogen gas accumulated to some extent in a timely manner will be described with reference to FIG. In this case, in addition to the structure for obtaining hydrogen water shown in FIG. 1, a movable upper lid container 16 for collecting and storing hydrogen gas is used.
Hydrogen dissolves in water at a maximum of 1.6 ppm, and surplus hydrogen becomes gas and rises in the cathode chamber 3 and accumulates in the upper lid container 16.
The upper lid container 16 has a hydrogen outlet 17 at the top, and a cock 18 is provided in the middle. The lowermost portion of the upper lid container 16 is open, and the side surface of the container is inscribed in the cathode chamber 3 and can move up and down.
When the cock 18 is opened at the start of electrolysis and the upper cover container 16 is pushed down into the cathode chamber 3 containing the raw electrolytic water or air is sucked from the hydrogen outlet port 17, the air in the upper cover container 16 can be eliminated. Thereafter, when the cock 18 is closed and electrolysis is started, only hydrogen gas accumulates in the upper lid container 16. A tube is connected to the hydrogen outlet port 17, and the cock 18 can be opened and sucked before the accumulated hydrogen gas is full.
In this way, it is possible to avoid the hydrogen gas generated by electrolysis from being mixed with the air and staying in the air, so that it is possible to eliminate the danger of hydrogen explosively burning by fire.

An embodiment for obtaining hydrogen water will be described with reference to FIG. The container 1 is made of transparent acrylic, has a base of 75 cm × 75 cm, a height of 150 cm, and a thickness of 2 mm. The partition wall 2 is also made of an acrylic plate, is spaced about 10 mm from one wall surface of the container 1, opens about 15 mm from the bottom surface of the container 1, and is inscribed and bonded to form the oxygen passage 12.
The negative electrode 5 is made of stainless steel and has a wire diameter of approximately 0.3 mm and a mesh opening of 1 mm. The depth is adjusted to the size of the lower part of the cathode chamber 3, and the lateral direction is extended by about 15 mm for connecting the controller. And cut. The filter 6 is a commercially available 0.12 mm thick polyester satin fabric having an effective pore diameter of about 50 μm, and is cut in accordance with the size of the lower part of the cathode chamber 3, and about 8 mm around the negative electrode 5. Adhesive is applied with a width so that the negative electrode 5 is adhered and integrated. Unlike the conceptual diagram of FIG. 1, the feeding portion 14 of the negative electrode is bent upward at a right angle to form a screw hole in the center. Then, a hole is also made in the container 1 at this position, and the negative electrode integrated with the filter 6 is horizontally attached with a screw. Wire from this screw to the constant current controller 11. Further, the negative electrode 5 integrated with the filter 6 is bonded to the lower part of the cathode chamber 3, and the separation as a countermeasure against reflux to the material cathode chamber 3 generated in the anode chamber 4 is completed.
Thus, if there is no difference in water pressure by the filter 6, the liquid and bubbles in both chambers will not circulate through both chambers. Next, two positive electrodes 7 having a rod shape and a straight line of 2 mm are attached to the lower part of the filter 6. A 2 mm-diameter hole is drilled at an interval of about 25 mm at the lower portion of the side surface of the container 1 and the positive electrode 7 is inserted. Externally connected to the constant current circuit 11.
It is important that the positive electrode is plated with platinum on a direct 2 mm titanium rod so that it does not corrode against active oxygen and ozone, and no metal other than the titanium surface and the platinum surface is present inside the anode chamber 4. The arrangement relationship between the electrode and the filter formed in this way is shown in FIGS.

At the start of electrolysis, 0.2 g of sodium bicarbonate was introduced from the oxygen exhaust port 13 of FIG. 1 and 500 cc of natural water having a pH of 8.0 (15 ° C.) was placed in the cathode chamber 3 of the container 1. In about 10 seconds, the anode chamber 4 was filled with an electrolytic solution in which sodium bicarbonate was dissolved. If this time is calculated considering that it may be several hours later, it is sufficient that the effective pore size of the filter 6 is 1 μm or more, and the direct line of ions and water molecules to be passed is much smaller than 1 μm and can be obtained at low cost. Since the pore diameter is generally 1 μm or more, the lower limit of the effective pore diameter of the filter 6 used in the present invention is 1 μm. It is also clearly distinguished from the fact that there is no hole of 1 μm or more in the electrolyte membrane of the prior art.
When power is supplied from the AC adapter 8 to the constant current circuit 11 adjusted to 480 mA, hydrogen bubbles start to be generated from the negative electrode 5, and in about 4 minutes, the raw water in the cathode chamber is fully clouded with microbubbles of hydrogen bubbles. did. Oxygen bubbles are generated around the positive electrode 7, and the oxygen bubbles, which are prevented from rising by the filter 6, search for the destination and end and expand. When the container 1 was tilted so that the bubble passage 12 was slightly above the lowermost part of the container, the expanded oxygen bubbles moved to the bubble passage 12 and were released from the oxygen discharge port 13 to the outside air. This indicates that both electrodes may be installed with the angle of inclination within 45 ° and the bubble passage 12 side on top.
The hydrogen concentration in the cathode chamber 3 at this time was taken out and the hydrogen concentration measured was 0.6 ppm. After 10 minutes, the hydrogen concentration became 1.0 ppm. The oxidation-reduction potential at this time was -640 mV (pH 9.0), and it was confirmed that hydrogen water having sufficient reducing power was produced.
It was also confirmed that if citric acid or vitamin C was added instead of baking soda as the electrolyte, the resulting hydrogen water became acidic and the choice was free.
It was also confirmed that tea, juice, milk, etc. can be used without using electrolytes added with tap water, purified water or natural water. These are foods with a slow reducing effect, and a current of 480 mA flows and sufficient hydrogen is dissolved, and a combined effect with hydrogen water can be expected.

Next, an example in which the behavior of bubbles and electrolyte during electrolysis is visualized to confirm the electrode arrangement and the effect of the filter 6 will be described although not shown. An acrylic container having a bottom surface of 70 mm × 70 mm and a height of 120 mm, 30 mm from the bottom of a transparent acrylic container, and two Yin and Yang electrodes with a diameter of 2 mm and a length of 50 mm, with a center distance of 20 mm. A hole was made in the side and inserted horizontally. Unlike the first embodiment, both electrodes are arranged not horizontally but horizontally, and the filter is arranged vertically instead of horizontally. Both electrode chambers are divided vertically, and both electrode chambers are open at the top.
First, unlike the present invention, the experiment is performed without using a filter. 0.5 g of sodium chloride was added to 500 cc of tap water, and electrolysis was performed for 10 minutes while stirring at 240 mA (27 V). The produced electrolyzed water was clouded with hydrogen bubbles, but the dissolved hydrogen concentration reagent did not react at all and the concentration was 0 ppm. When a small amount of potassium iodide is added to the generated electrolyzed water, it turns yellowish brown and the dissolution of hypochlorous acid is confirmed, and even when no salt is added to tap water, dissolved ozone is detected in most cases. The problem in the case of the non-diaphragm type and not using the filter of the present invention was obvious.

Next, a groove is formed in the center of the container, and a filter according to the present invention is attached to separate the two electrodes into a cathode chamber and an anode chamber, thereby realizing the object of the present invention most simply. The filter used was a nylon mesh having a wire diameter of 120 μm and a spread of 500 μm. Unlike the first embodiment, the filter is vertical, the electrodes are one each and the distance between the electrodes is large, and the negative electrode is not a mesh but a rod shape and does not support the filter. The same.
This time, 1.0 g of sodium chloride and 0.1 g of potassium iodide as electrolytes were added to 500 cc of tap water and placed in a container. Then, this filter was attached to separate both electrode chambers, and 240 mA (28 V without stirring). ) Was electrolyzed. After about 2 minutes, hydrogen bubbles were limited to the upper part of the cathode electrode and refluxed in the cathode chamber, and only the upper part became cloudy. In other words, it has been clarified that it is preferable to dispose the negative electrode at the lowermost part of the cathode chamber in order for hydrogen bubbles to reach the raw water of the entire cathode chamber and to make the whole into hydrogen water.
At this time, the hydrogen concentration in the upper part of the cathode chamber was 0.6 ppm. On the other hand, in the anode chamber, potassium iodide was oxidized at the positive electrode to become yellowish brown, and after 8 minutes, the entire anode chamber became dark yellowish brown. However, this tan liquid does not reflux to the cathode chamber at that time. After the electrolysis was stopped, it was confirmed that the yellowish brown liquid finally refluxed and moved about 5 mm in the upper part of the cathode chamber after 10 minutes had passed.
In addition, it was confirmed that the hydrogen bubbles of the microbubbles in the cathode chamber had entered the anode chamber from the filter, but the movement of oxygen bubbles to the cathode chamber was not confirmed.
Thus, it was determined that the mesh having a spread of 500 μm used in Example 2 was the upper limit of the spread so that the product of the bipolar chamber would not be mixed within about 10 minutes for practical use.
In Example 1, the lower limit of the effective pore diameter of the filter 6 is clarified, and when these are combined, the effective pore size range of the filter 6 used in the present invention is 1 μm to 500 μm.

  Next, Example 3 for obtaining hydrogen gas will be described with reference to FIG. The filter 6 is arranged vertically as in the second embodiment, but the assembly of both electrodes and the filter is the same as that of the first embodiment, and is arranged perpendicular to the horizontal arrangement. Accordingly, the negative electrode 5 is made of stainless steel and generates hydrogen bubbles at the top as in the second embodiment. However, since the hydrogen bubbles do not rotate below or far away from the negative electrode 5, high concentration of hydrogen is present throughout the cathode chamber. The structure for obtaining water is not preferable. However, oxygen is immediately released to the outside air. The upper lid 20 is bonded to the upper part of the cathode chamber 3 so as to seal the cathode chamber 3. When an electrolytic solution to which an electrolyte is added is put into purified water or the like from the upper part of the anode chamber, the cathode chamber 3 can be exhausted with air and filled with the electrolytic solution through the filter 6. Thus, hydrogen gas can be obtained continuously by connecting a tube to the hydrogen outlet 17 and starting electrolysis.

Next, an embodiment in which either hydrogen water or hydrogen gas can be obtained in a timely manner will be described with reference to FIG. In the case of obtaining hydrogen water, if the upper lid container 16 is removed, the same result as in the first embodiment is obtained. In order to obtain hydrogen gas, the upper lid container 16 is newly arranged as shown in FIG. An acrylic cup almost inscribed in the cathode chamber 3 is prepared and turned downward. A direct hole of 3 mm was made in the bottom of the cup, a silicone tube was connected from above, and the cathode chamber 3 was placed through the opening of the cup that came down. In addition, a stop pin is prepared for the silicone tube to enable opening and closing. The method of adding sodium bicarbonate to the electrolytic raw water is the same as in Example 1.
Electrolysis was started after sucking air from the silicone tube and extracting air from the cup. When the amount of hydrogen gas in the cup was measured in about 30 minutes, about 50 cc was confirmed. As described above, the hydrogen can be sucked from the mouth by opening the stop pin after an appropriate time has elapsed.
Alternatively, it was confirmed that a trace amount of hydrogen gas can be continuously sucked by using a canola for oxygen suction instead of a silicone tube.
In the case of continuous inhalation, when a large amount of hydrogen gas is accumulated in the upper lid container 16, the water level in the upper lid container 16 is lowered, and a pressure for discharging the hydrogen gas is generated.
The present embodiment is intended to provide an electrolytic hydrogen generator capable of drinking hydrogen water and sucking hydrogen gas. If the upper lid 20 as shown by the dotted line is attached to the apparatus shown in FIG. 1, the hydrogen gas is taken out. Such a movable upper lid is not indispensable for obtaining hydrogen gas in the present invention because it also becomes a dedicated device. In this way, a certain amount or more of hydrogen gas does not stay mixed with air, and the continuously generated hydrogen gas is limited to electrolysis, so that it is a very small amount and is safe against explosion.
While performing continuous electrolysis, the ozone odor was clearly confirmed by bringing the nose close to the oxygen exhaust port 13.
At this time, however, ozone was not detected in the hydrogen water in the cathode chamber.

All of the above embodiments have shown only some examples of the present invention.
It was also confirmed that the material of the filter 6 may be a cloth made of chemical fiber or cotton, paper, metal or resin mesh, or porous ceramic. However, it is required that it does not deteriorate significantly even when it comes into contact with ozone. Further, when a metal mesh is used, it is necessary to arrange so as to avoid contact with both electrodes. Such a filter 6 is preferably a cloth in consideration of the price. The cloth is not limited to a woven cloth but may be a non-woven cloth. Nonwoven fabrics only have uneven effective pore sizes. Considering these, most sheets of materials used in the interelectrode insulating separator in the electrochemical region can be diverted. However, the filter 6 of the present invention is clearly specified again that the role and the arrangement structure are essentially different from those of the separators for isolating only the electrodes.
As for the positive electrode 7, the substrate is preferably made of titanium having a thick nano film on the surface, and the surface is not limited to platinum, and any metal or DLC that does not corrode by the reaction of the anode where active oxygen is generated can be used. is there. If the substrate is not titanium, corrosion will start if pinholes are formed in the surface coat. However, graphite and carbon rods can be used as long as they are oxidized and allow the surface to dissolve little by little, and the shape is also free. Although it is a little expensive, the positive electrode 7 may have a mesh structure, and the filter 6 may be partly bonded and integrated.
Needless to say, the current value of the constant current control can be set freely in consideration of the amount of the added electrolyte and the temperature. The amount of hydrogen gas produced can easily be calculated according to Faraday's law, and is in fact consistent.
If the electrolyte contains alkali metal ions such as sodium, the ions move to the cathode chamber, so that the raw water in the cathode chamber contains hydrogen and the alkalinity increases. It was confirmed that the pH was 12.4 (20 ° C.) after 6 hours of electrolysis. It should also be noted that in long-term electrolysis over several hours, hydrogen water in the cathode chamber becomes cleaning water that is not suitable for drinking.
In addition, the present invention is not limited to the contents of the examples and supplementary explanations, and can be applied in various ways without departing from the essence of the invention.

    The electrolytic hydrogen generator according to the present invention can be used as a device for generating inexpensive and simple hydrogen water and hydrogen gas for home and medical use.
