る。[Function and Effect] Since the acidic aqueous solution is taken from the upper part of the hydrogen generating tank to the outside of the hydrogen generating tank and is sent to the bottom of the hydrogen generating tank, the acidic aqueous solution naturally flows inside the hydrogen generating tank. However, a liquid flow path of the acidic aqueous solution from the bottom to the top in the hydrogen generation tank is formed. Then, since at least a part of the portion made of the metal of the hydrogen generator is immersed in the liquid flow path, hydrogen generated around the metal is generated by the flow of the acidic aqueous solution in the liquid flow path. Accordingly, the hydrogen flows from the bottom to the top in the hydrogen generation tank, and the floating action of the bubbles of hydrogen in the acidic aqueous solution to the liquid surface is promoted. Therefore, according to this configuration,
Since hydrogen bubbles generated in the acidic aqueous solution easily float to the liquid surface, hydrogen is more likely to be generated from the hydrogen generation tank, and the hydrogen generation efficiency can be improved.

より向上させることができるようにもなる。Further, as described above, hydrogen generated around the metal easily floats up to the liquid surface, so that it can be expected that hydrogen is relatively hard to stay around the metal as compared with the conventional case. Therefore, the phenomenon that the hydrogen generation action is suppressed due to the retention of hydrogen around the metal is mitigated, and as a result, the hydrogen generation efficiency from the hydrogen generation tank can be further improved. Also becomes.

ことを期待することもできる。Further, in the conventional technique, the surface of the solution and the metal change as the reaction proceeds in the acidic aqueous solution, and the hydrogen generation efficiency decreases. When the acidic aqueous solution flows and circulates in the hydrogen generation tank, the quality of the acidic aqueous solution in the hydrogen generation tank becomes very uneven near the metal surface in the hydrogen generation tank and at a location apart from the metal. It is easy to obtain a relatively uniform surface, and the surface of the metal also changes uniformly throughout.As a result, it is possible to maintain a high hydrogen generation efficiency from the hydrogen generation tank. You can also expect.

The acidic aqueous solution A stored in the hydrogen generating tank 1
A liquid receiving portion 16 that is configured to be overflowable from the top of the hydrogen generating tank 1 and that can receive and store the overflowed acidic aqueous solution A is provided around the outer periphery of the hydrogen generating tank 1 and is stored in the liquid receiving portion 16. This is where a feed passage 33 is provided for sending the acidic aqueous solution A to the bottom of the hydrogen generating tank 1.

ができる。[Operation and Effect] According to this configuration, it is possible to reduce the possibility that bubbles of hydrogen produced in the acidic aqueous solution in the hydrogen production tank are mixed in the acidic aqueous solution in the liquid circulation path. The effect of claim 1 described above can be more reliably enjoyed, and the hydrogen generation efficiency can be more reliably improved.

酸性水溶液中に水素の気泡が混入する割合は低下され、

のである。That is, since the acidic aqueous solution stored in the hydrogen generating tank is once overflowed from the top of the hydrogen generating tank and then supplied to the liquid receiving portion constituting the liquid circulation path, the hydrogen generating solution is generated. The bubbles of hydrogen generated in the acidic aqueous solution in the tank float up to the liquid surface of the acidic aqueous solution without being significantly hindered and are reliably separated and separated from the acidic aqueous solution. Hydrogen is easily generated from the production tank. Therefore, the proportion of hydrogen bubbles mixed in the acidic aqueous solution supplied to the liquid receiving section is reduced,
The risk of hydrogen bubbles being mixed in the liquid circulation path is reduced.

部からも水素を発生させることができるようになる。Moreover, since the liquid receiving portion is constructed so as to store not only the acidic aqueous solution overflowed from the hydrogen generating tank but also the acidic aqueous solution supplied to the liquid receiving portion, it is immediately circulated. It is stored in the liquid receiving part that takes a certain period of time without being stored. Therefore, even if hydrogen bubbles are mixed in the acidic aqueous solution that overflows from the hydrogen generation tank, the hydrogen bubbles will remain on the liquid surface that is the contact interface with the outside air while being stored in the liquid receiving section. By being floated up to, more is separated from the acidic aqueous solution. Therefore, by separating the bubbles of hydrogen mixed in the liquid circulation path from the acidic aqueous solution, it is possible to reduce the proportion of bubbles of hydrogen mixed in the liquid circulation path and also to generate hydrogen from the liquid receiving section. become able to.

される。Since the acidic aqueous solution stored in the liquid receiving section is sent to the bottom of the hydrogen generating tank by the sending channel and circulated, a liquid flow path is formed in the hydrogen generating tank as described above. As a result, the floating action of hydrogen bubbles on the liquid surface is promoted.

【００１４】従って、水素の気泡が液循環路の酸性水溶

ことができる。Further, since it is possible to reduce the possibility that hydrogen bubbles stay in the acidic aqueous solution in the liquid circulation path as described above,
For example, when a liquid circulation pump is provided in the feed passage in the liquid circulation passage to circulate the acidic aqueous solution, there are the following advantages. That is, since bubbles are less likely to be mixed with the acidic aqueous solution in the liquid circulation pump, it is possible to stably circulate a predetermined set amount of the acidic aqueous solution, and it is difficult for bubbles to be entangled in the circulation pump to prevent its rotation. Can be maintained normally. As a result, the high hydrogen generation efficiency can be stably maintained.

The dissimilar metals M1 and M2 having different ionization tendencies are immersed in a state of being electrically connected to each other.

The smaller the value, the more the oxidation reaction is promoted, while the one having a larger ionization tendency accelerates the reduction reaction of hydrogen generation from the acidic aqueous solution. Therefore, as a result, hydrogen generation from the hydrogen generation tank can be promoted, and a large amount of hydrogen can be generated in a short time.

Therefore, as an example, the first bottom wall 13 is provided at a position slightly higher than the lower end of the first peripheral wall 11 so as to be offset from the lower end of the first peripheral wall 11 to form the supply space. At the same time, a large number of through holes 15 are concentrically formed in the first bottom wall 13 itself. Therefore, the acidic aqueous solution circulated through the liquid circulation path 3 is stored in the storage unit 1.
When supplied to the inside, the acidic aqueous solution supplied from below the first bottom wall 13 by the liquid circulation path 3 does not proceed into the storage part 1 as it is, but at an area where the through hole 15 is not formed. The first bottom wall 13 serves as a barrier, is appropriately dispersed in the supply space, and facilitates the uniform supply of the acidic aqueous solution from the entire first bottom wall 13 to the storage portion 1 through the through holes 15. Therefore, the liquid flow path of the acidic aqueous solution from the bottom portion to the upper portion is easily formed uniformly in the entire storage portion 1, so that the volume of the storage portion 1 can be effectively used while the liquid of the acidic aqueous solution of the metal is used. It becomes possible to immerse in the flow path, and as a result, the hydrogen generation efficiency can be further improved.

When the aqueous solution A exceeds the volume of the storage section 1, the acidic aqueous solution A can overflow from the top of the storage section 1. Then, the overflowed acidic aqueous solution A is received and stored by the liquid receiving portion 16 provided around the outer periphery of the storage portion 1. That is, in the embodiment, the liquid receiving portion 16 is composed of the first peripheral wall 11, the second peripheral wall 12 and the second bottom wall 14, and the first peripheral wall 11, the second peripheral wall 12 and the second bottom wall. The acidic aqueous solution overflowing from the storage unit 1 is received and stored in the space surrounded by 14.

でき、経済的である。Further, the second peripheral wall 12 is provided with a discharge port 31 through which the acidic aqueous solution A stored in the liquid receiving section 16 can be discharged to the outside of the liquid receiving section 16. Incidentally, in the embodiment, when the discharge port 31 is provided, as shown in FIG. 1, it is provided in the lower portion of the liquid receiving portion 16 (for example, the peripheral wall 12 near the upper end of the second bottom wall 14). It is possible to expect various operational effects. In other words, in the liquid receiving section 16,
Since the overflowed acidic aqueous solution is supplied from the top of the storage section (hydrogen generation tank) 1, when hydrogen bubbles are mixed in the acidic aqueous solution stored in the liquid receiving section 16,
It is predicted that a high proportion of hydrogen bubbles having a relatively large bubble diameter that have floated to the liquid surface of the reservoir 1 are mixed. Therefore, the hydrogen bubbles mixed in the acidic aqueous solution stored in the liquid receiving section 16 easily float to the liquid surface in a relatively short time, and are more acidic than the lower portion of the liquid receiving section 16 than near the upper portion near the liquid surface. Discharging the aqueous solution can reduce the possibility that hydrogen bubbles are mixed in the discharged acidic aqueous solution. Further, since the acidic aqueous solution is in a large amount above the height position of the discharge port 31, the energy required to discharge the acidic aqueous solution from the discharge port 31 can be reduced, which is economical.

As shown in, it is preferable that the metal M1 and the metal M2 are connected to each other by the conductive wire 8 in the state where the separated space is provided. In addition, it is more preferable that the conductive wire 8 is not immersed in the acidic aqueous solution. As an example, Zn is used as the metal M1, Cu is used as the metal M2, and sulfuric acid is used as the acidic aqueous solution. The whole is immersed in sulfuric acid in a state where Zn and Cu are directly contacted. Zn and C so that the connection point and the lead wire are located outside the sulfuric acid.
A test was conducted to compare the amount of hydrogen generated in two types of immersion states of u in sulfuric acid (see FIG. 6). The other test conditions were set to be the same, and the test was conducted. The result is shown in FIG. As can be seen from FIG. 7, it was confirmed that under the conditions, it is possible to obtain 1.3 times the volume of hydrogen in terms of volume ratio.

The stable film 10 may be provided. For example, when the hydrogen generator is used by being mounted on a moving body such as an automobile, the hydrogen generator vibrates as the moving body moves, and the like The surface may fluctuate, and the amount of hydrogen generated may drop sharply. However, if the liquid level stabilizing film 10 is provided as described above, fluctuations in the level of the acidic aqueous solution (for example, above and below the level). It is possible to suppress the fluctuation of the water level of the acidic aqueous solution, and as a result, the contact area between the metal M1 (or the dissimilar metals M1 and M2) and the acidic aqueous solution is stably maintained. It is possible to stabilize the hydrogen generation amount.

度や発生量を調節することができる。<9> Then, changes in the hydrogen generation rate depending on the pH and temperature of the acidic aqueous solution stored in the hydrogen generation tank were investigated. The results are shown in FIGS. Figure 11
When the dissimilar metals Zn and Cu are electrically connected to each other and immersed in an acidic aqueous solution, the dissimilar metals Mg and Cu are shown in FIG.
The figure shows the case where the sample is immersed in an acidic aqueous solution in a state of being electrically connected. In addition, in all cases, the temperature of the acidic aqueous solution was 20 ° C. As shown in FIGS. 11 and 12, it was found that the higher the pH of the acidic aqueous solution, the slower the hydrogen generation rate. Also, as can be seen from FIGS.
The lower the pH of the acidic aqueous solution, the higher the rate of hydrogen generation. Therefore, when a large amount of hydrogen is required in a short time, the acidic aqueous solution may be controlled to be maintained in a relatively low pH range. , Zn metal, the pH is 0.5
Below, in the case of Mg metal, the pH may be maintained at 0.9 or less (see FIGS. 11 and 12 (a)). On the other hand, when a certain amount of hydrogen is required stably over a long period of time, controlling the acidic aqueous solution to maintain a relatively high pH range will result in a significant change in the hydrogen generation rate even if the pH changes. Therefore, it is preferable that the pH of Zn metal is controlled in the range of 0.5 to 0.7, and that of Mg metal is controlled in the range of 1.04 to 1.1. All you have to do is (see Fig. 11 and 12 (b)). As shown in FIG. 13, the temperature of the acidic aqueous solution is 5 ° C., 20 ° C.
It was found that the higher the temperature was ℃, 30 ℃, 60 ℃, the higher the hydrogen generation rate (test conditions: different metals Zn and Cu were electrically connected, immersed in an acidic aqueous solution, pH
0.5). Therefore, the pH and the temperature of the acidic aqueous solution can be set to predetermined values respectively according to various usage patterns, and the generation rate and the generation amount of hydrogen can be adjusted.
