According to the first aspect of the invention, the hydrogen storage alloy A1 of the first MH container 1 is kept at a relatively low temperature by the heat source 35 in a state where hydrogen is stored in the hydrogen storage alloy A1 of the first MH container 1. When heated and less than a predetermined pressure, it is difficult to form a hydride. As the heat source 35, an unused heat source such as sewage or geothermal heat can be used. From this state, hydrogen is forcibly sent from the first MH container 1 to the second MH container 2. As a result, hydrogen is released from the hydrogen storage alloy A1, the hydrogen storage amount gradually decreases, and the released hydrogen is sent to the second MH container 2 at a relatively high pressure.

As a result, an exothermic reaction due to hydrogen storage occurs in the hydrogen storage alloy A2 of the second MH container 2, so that the second M
The temperature of the heated portion 10a can be raised by the heat generated in the H container 2. By making the heated portion 10a a road surface, a roof, or the like, it is possible to prevent snow melting and freezing of these.

According to the invention of claim 2, the first MH container 1
Hydrogen is stored in the hydrogen storage alloy A1 of
With the hydrogen closed, the hydrogen storage alloy A1 of the first MH container 1
Is heated to a relatively low temperature by an unused heat source 35,
If the pressure is less than the predetermined pressure, it is difficult to form a hydride. As the heat source 35, an unused heat source such as sewage or geothermal heat can be used. From this state, the compressor 4 is driven to drive the first MH.
The pressure inside the container 1 is reduced. As a result, hydrogen is released from the hydrogen storage alloy A1, and the released hydrogen is sent to the second MH container 2 at a relatively high pressure.

As a result, in the second MH container 2, hydrogen is effectively stored in the hydrogen storage alloy A2 while the internal pressure is increased by the inflow of hydrogen, and the temperature is raised to a predetermined temperature by the heat generated by the exothermic reaction. , Keep absorbing hydrogen. Since the heated portion 10a can be heated by raising the temperature of the hydrogen storage alloy A2, snow, ice, etc. on the heated portion 10a can be melted and refreezing can be prevented.

When hydrogen is stored in the hydrogen storage alloy A2 in the second MH container 2, the driving of the compressor 4 is stopped, the opening / closing valve 14 is opened, and the hydrogen in the second MH container 2 is passed through the flow path 15 to the first MH. It is introduced into the container 1.
As a result, the pressure inside the second MH container 2 is reduced, and the release of hydrogen from the hydrogen storage alloy A2 is promoted. At the same time, the pressure inside the first MH container 1 is increased based on the pressure difference between the two MH containers 1 and 2, so that hydrogen is stored in the hydrogen storage alloy A1. Second
When hydrogen is released from the hydrogen storage alloy A2 of the MH container 2 and hydrogen is stored in the hydrogen storage alloy A1 of the first MH container 1, and the initial storage amount is restored, the on-off valve 14 is closed.

As described above, since the hydrogen in the first MH container 1 is forcibly sent into the second MH container 2 by using the compressor 4 to generate a pressure difference, both hydrogen storage alloys A
Even when the temperature difference between 1 and A2 is small, hydrogen absorption and desorption can be repeated.

According to the invention of claim 3, the on-off valve 14
When the hydrogen in the second MH container 2 is introduced into the first MH container 1 through the flow path 15, the pump 3 is driven to circulate the heat medium through both heat medium passages 1a and 2a. As a result, the hydrogen storage alloy A2 of the second MH container 2 does not cause an excessive temperature drop due to the endothermic reaction, and the release of hydrogen is maintained. The hydrogen occlusion action is maintained without causing an excessive temperature rise.

According to the invention of claim 4, the first MH container 1
Hydrogen is stored in the hydrogen storage alloy A1 of
With the hydrogen closed, the hydrogen storage alloy A1 of the first MH container 1
Is the heating medium passages 20a, 2 for heating by the heat source 35.
It is heated to a relatively low temperature by the heat medium in 0b, and it is difficult to form a hydride at a pressure lower than a predetermined pressure. As the heat source 35, an unused heat source such as sewage or geothermal heat can be used.

If the compressor 4 is driven from this state, hydrogen is released from the hydrogen storage alloy A1 as the pressure in the first MH container 1 drops, and the released hydrogen is released into the second MH.
It is sent to the container 2 at a relatively high pressure and stored in the hydrogen storage alloy A2. In the first MH container 1, a depressurization tendency is exhibited, hydrogen release is promoted, and an endothermic reaction occurs. However, since the heat medium in the heating medium passage 20a is heated by the heat source 35, an excessive temperature decrease occurs. To be prevented. On the other hand, the second MH
In the container 2, hydrogen is effectively stored in the hydrogen storage alloy A2 while increasing the pressure, and an exothermic reaction occurs. Due to the heat generated by the exothermic reaction of the hydrogen storage alloy A2, the temperature rising part 10a can be heated. This makes it possible to melt snow, ice, etc. near the heated portion 10a,
Refreezing can be prevented.

When hydrogen is stored in the hydrogen storage alloy A2 in the second MH container 2, the drive of the compressor 4 is stopped and the opening / closing valve 14 is opened to introduce the hydrogen in the second MH container 2 into the first MH container 1. To do. As a result, the second MH
Hydrogen is released in the container 2, and the first MH container 1
Then hydrogen is absorbed. At that time, the second MH container 2 is heated to a predetermined temperature by the heating heat medium passage 20b to promote release of hydrogen, and the first MH container 1 generates reaction heat due to storage of hydrogen.

Therefore, the temperature of the heated portion 10a can be raised by the heat generated by the hydrogen storage alloy A1 of the first MH container 1. As a result, snow, ice, etc. near the heated portion 10a can be melted and refreezing can be prevented. As described above, since the pressure in the first MH container 1 is forcedly sent into the second MH container 2 by using the compressor 4 to generate the pressure difference, it is possible to reduce the temperature difference between the hydrogen storage alloys A1 and A2. Even at that time, hydrogen can be stored and released repeatedly.

According to the fifth aspect of the present invention, since the heating heat medium passages 20a and 20b are connected to the tank 28 which can be heated by the heat source 35, the heating heat medium passage 20 is provided.
The heating of the hydrogen storage alloys A1 and A2 of the first and second MH containers 1 by a and 20b is performed by introducing the heating medium in the tank 28 into the heating heating medium passages 20a and 20b.

H container is shown. The second MH container 2 is buried in the surface layer of the road 10, and the first MH container 1 is buried in a proper place in the ground. The hydrogen storage alloys A1 and A2 are arranged in the MH containers 1 and 2 so as to be partitioned by the air-permeable filters 1b and 2b, and the hydrogen spaces 1c and 2c are provided in the MH containers 1 and 2.
Is formed. Hydrogen enters and leaves the hydrogen spaces 1c and 2c. In addition, in each hydrogen storage alloy A1, A2,
Heat medium passages 1a and 2a for heating or cooling the hydrogen storage alloys A1 and A2 are attached. Here, the hydrogen storage alloys A1 and A2 are, for example, TiZrCrFeMnNiCu based alloys. In the figure, hydrogen spaces 1c and 2c are formed in the upper part of each MH container 1 and 2, and hydrogen storage alloys A1 and A2 are formed in the lower part.
However, it is also possible to form the hydrogen spaces 1c and 2c in the lower part and accommodate the hydrogen storage alloys A1 and A2 in the upper part.

Thus, the second MH container 2 has the road surface 10a.
The hydrogen storage alloy A of the first MH container 1 arranged close to
No. 1 is arranged at a location where it can be heated to a relatively low temperature (for example, about 10 ° C.) by an unused heat source 35, for example, sewage, underground geothermal heat, or the like. The road surface 10a may be a temperature-raised part that needs to be heated for snow melting or the like, and may be a roof or the like.

Since the hydrogen storage alloy A1 is in a state in which it is difficult to form a hydride at a pressure lower than the predetermined pressure, hydrogen tends to be easily released.
From this state, the compressor 4 is driven to reduce the pressure inside the first MH container 1. As a result, hydrogen is released from the hydrogen storage alloy A1, and a point H is shown in FIG. 2 (hydrogen pressure-composition isotherm diagram).
As shown at point I, the hydrogen storage amount gradually decreases, and the released hydrogen is sent to the second MH container 2 at a relatively high pressure through the pipe 13.

That is, the inside of the first MH container 1 is gradually depressurized and continues to release hydrogen. On the other hand, in the second MH container 2 cooled by snow or ice, the one having a small hydrogen storage amount as shown by the point J in FIG. 2 does not enter the hydrogen as shown by the points J to K in FIG. As a result, hydrogen is effectively stored in the hydrogen storage alloy A2 while the internal pressure increases, and the heat generated by the exothermic reaction raises the temperature to a predetermined temperature (for example, about 30 ° C.) and continues to store hydrogen. Since the road surface 10a is heated by the temperature rise of the hydrogen storage alloy A2, snow on the road surface 10a,
The ice is melted and refreezing is prevented.

When hydrogen has been sufficiently stored in the hydrogen storage alloy A2 in the second MH container 2, the driving of the compressor 4 is stopped and the opening / closing valve 14 is opened to open the second MH container 2
The hydrogen therein is introduced into the first MH container 1 through the flow path 15. As a result, the inside of the second MH container 2 is depressurized while being cooled by snow, ice, or the like on the road surface 10a, and the release of hydrogen from the hydrogen storage alloy A2 is promoted. At the same time, both MH
Since the pressure inside the first MH container 1 is increased based on the pressure difference between the hydrogen spaces 1c and 2c of the containers 1 and 2, the heat of reaction is the heat source 3
While being absorbed by 5, hydrogen is absorbed by the hydrogen storage alloy A1.

When the opening / closing valve 14 is opened and the pump 3 is driven, the heat medium is transferred to both heat medium passages 1a, 2
a and the pipes 11 and 12 are circulated. This allows
The hydrogen storage alloy A2 of the second MH container 2 does not undergo excessive temperature drop due to the endothermic reaction, and the release of hydrogen is maintained, and at the same time, the hydrogen storage alloy A1 of the first MH container 1 has an excessive temperature accompanying the exothermic reaction. The hydrogen occlusion action is maintained without increasing. The release of hydrogen in the second MH container 2 is performed as shown at points L to M in FIG. 2, and the storage of hydrogen in the first MH container 1 is performed as shown at points N to O in FIG. The pressure inside the MH containers 1 and 2 is almost the same (see P

When sufficient hydrogen is released from the hydrogen storage alloy A2 of the second MH container 2 and sufficient hydrogen is stored in the hydrogen storage alloy A1 of the first MH container 1 and the initial storage amount is restored, opening / closing The valve 14 is closed and the driving of the pump 3 is stopped. By driving the pump 3, both M
By promoting the equalization of temperature between the H containers 1 and 2,
The road surface 10a is prevented from being excessively cooled due to an endothermic reaction accompanying the release of hydrogen from the hydrogen storage alloy A2 of the second MH container 2, and the hydrogen storage alloy A1 of the first MH container 1 is prevented. It is possible to satisfactorily prevent the hydrogen storage alloy A1 from inhibiting the hydrogen storage due to the exothermic reaction accompanying the storage of hydrogen.

As described above, since the hydrogen in the first MH container 1 is forcibly sent into the second MH container 2 by using the compressor 4 to generate a pressure difference, both hydrogen storage alloys A
Even when the temperature difference between 1 and A2 is small, hydrogen absorption and desorption can be repeated.

By repeating such operations, the road surface 1
The snow, ice, etc. on the surface 0a are intermittently heated and melted, and the antifreezing action can be obtained for a long time. It is also possible to continuously heat the road surface 10a by arranging a plurality of heating devices having the above-mentioned configuration and performing the hydrogen absorption and desorption in both MH containers 1 and 2 in opposite phases.

The hydrogen can be refluxed toward the MH container 1.

Next, the operation of the second embodiment will be described. With sufficient hydrogen stored in the hydrogen storage alloy A1 of the first MH container 1 and the opening / closing valve 14 closed, the hydrogen storage alloy A1 of the first MH container 1 is heated by the unused heat source 35. It is heated to a relatively low temperature (about 10 ° C.) by the passage 20a. Since the hydrogen storage alloy A1 is in a state in which it is difficult to form a hydride at a pressure lower than the predetermined pressure, hydrogen tends to be easily released.

When the compressor 4 is driven from this state, hydrogen is released from the hydrogen storage alloy A1 of the first MH container 1 as shown by points P to Q in FIG. 4 (hydrogen pressure-composition isotherm diagram), and released.

However, due to the heat generation of the hydrogen storage alloy A1 of the first MH container 1, the temperature of the heat-releasing heat medium passage 21a rises, and the heated heat medium flows into the tank 27 by convection. Receives heat and rises in temperature. As a result, snow, ice, etc. on the road surface 10a are melted and freezing is continuously prevented.
