[0003] The existing hydrogen power system usually includes fuel cell and solid-state hydrogen storage device, and usually supplies gas to the fuel cell device through the solid-state hydrogen storage device. However, the solid-state hydrogen storage device releases heat to the outside during the gas supply process, which causes the bottle body temperature to decrease, and as the bottle body temperature decreases, the hydrogen supply efficiency also gradually decreases. In order to solve this problem, the existing solid-state hydrogen storage device mainly heats the solid-state hydrogen storage device when hydrogen is released, so that the solid-state hydrogen storage material releases hydrogen at a higher temperature under reduced pressure. The current heating method for the solid-state hydrogen storage device is mainly electric heating, which is low in efficiency, and causes waste of heat during the heating process. In the heating process, there are also problems such as uneven heating, slow heating speed, etc.

A part of the gas cylinder is mounted in the mounting hole 21, the lower end of the gas cylinder faces the second shell 12, and the upper end of the gas cylinder faces the first shell 11, that is, the gas cylinder is mounted in the mounting hole 21 in the up-down direction, and the gas cylinder is used for supplying gas to the fuel cell device; a part of the gas cylinder in the self-axis direction is located in one subspace, and another part of the gas cylinder in the self-axis direction is located in another subspace. The driving fan 4 can drive the heat generated when the fuel cell device 200 works to enter the containing space 14 through the first opening 1311, and finally flow out through the second opening 1321 after flowing through multiple subspaces, for example, the driving fan 4 is arranged at the first opening 1311 and / or the second opening 1321, and can drive hot air to enter the containing space 14. It can be understood that the second side plate 132 is provided with the second opening 1321, so as to facilitate the control of the temperature in the containing space 14, and to release the heat in the containing space 14 to the outside, so as to prevent the internal temperature from being too high.

[0085] According to an embodiment of the utility model, the first shell 11 is located above the second shell 12, and the third shell 13 is located between the first shell 11 and the second shell 12; a part of the flow guide 2 is connected with the third shell 13, another part of the flow guide 2 is spaced apart from the third shell 13 to form a gap 144, the containing space 14 is divided into multiple subspaces in the up-down direction by the flow guide 2, and adjacent two subspaces are communicated through the gap 144; the bottom of the gas cylinder faces the second shell 12, the gas outlet end of the gas cylinder faces the first shell 11, a part of the gas cylinder in the self-axis direction is located in one subspace, and another part of the gas cylinder in the self-axis direction is located in another subspace.

It can be understood that the connection mode of the third shell 13 is not limited to this, which can be directly connected or indirectly connected.

In this embodiment, by using the flow guide 2, the accommodation space 14 can be divided into multiple subspaces in the up-down direction, and the adjacent two subspaces in the up-down direction can be communicated through the gap 144.

[0089] It can be understood that since a part of the gas cylinder in the axial direction of the gas cylinder is located in one subspace, and another part of the gas cylinder in the axial direction of the gas cylinder is located in another subspace, each subspace can correspond to a part of the gas cylinder, so that different parts of the gas cylinder can be heated by the gas with heat.

The flow guide 2 has the first space 141 with the first shell 11, and the flow guide 2 has the second space 142 with the second shell 12, and the gap 144 is communicated with the first space 141 and the second space 142 respectively.

The third space 143 is arranged between the first flow guide and the second flow guide, the third space 143 is arranged between the m-1 flow guide and the m flow guide, and the gas with heat flowing to the third space 143 heats the part of the gas cylinder located in the third space 143.

[0101] Optionally, at least a part of the edge of the flow guide 2 is provided with a turned edge. After punching on the turned edge, it can be fixed with the third side plate 133 or the fourth side plate 134 by screws. For example, the two sides of the first flow guide are provided with upward turned edges, the edge of one side of the first flow guide is fixed with the third side plate 133 by screws, the edge of the other side of the first flow guide is fixed with the fourth side plate 134 by screws, one end of the first flow guide is connected with the first side plate 131, and the other end is spaced apart from the second side plate 132 and forms a gap 144.

[0102] According to one embodiment of the utility model, the number of gas storage cylinders is multiple, along the direction from the first side plate 131 to the second side plate 132, the multiple gas storage cylinders are divided into multiple rows of gas storage cylinders, the multiple rows of gas storage cylinders include the first row of gas storage cylinders, the second row of gas storage cylinders, the N-1th row of gas storage cylinders, the Nth row of gas storage cylinders and the N+1th row of gas storage cylinders, each row of gas storage cylinders includes one or more gas storage cylinders, the number of gas storage cylinders of the N-1th row of gas storage cylinders is same with the number of gas storage cylinders of the N+1th row of gas storage cylinders, the number of gas storage cylinders of the Nth row of gas storage cylinders is less than or greater than the number of gas storage cylinders of the N-1th row of gas storage cylinders.

[0103] For example, as shown in the figure, Figure 13 The number of gas storage cylinders is 10, which is divided into four rows, and the four rows of gas storage cylinders are arranged in sequence along the direction from the first side plate 131 to the second side plate 132. Each row includes multiple gas storage cylinders, and the multiple gas storage cylinders are arranged in sequence along the direction from the third side plate 133 to the fourth side plate 134. The first row of gas storage cylinders is close to the first opening 1311, and the second row of gas storage cylinders, the third row of gas storage cylinders and the fourth row of gas storage cylinders are sequentially arranged behind the first row of gas storage cylinders, and the fourth row of gas storage cylinders is close to the second opening 1321. Among them, the first row of gas storage cylinders and the third row of gas storage cylinders respectively include two gas storage cylinders, and the second row of gas storage cylinders and the fourth row of gas storage cylinders respectively include three gas storage cylinders. Or also can be, the first row of gas storage cylinders and the third row of gas storage cylinders respectively include three gas storage cylinders, and the second row of gas storage cylinders and the fourth row of gas storage cylinders respectively include two gas storage cylinders. It can be understood that the width of the row of gas storage cylinders with less number is also narrower, and the width here refers to the maximum distance between the outermost two gas storage cylinders in a row of gas storage cylinders in the direction from the third side plate 133 to the fourth side plate 134.

[0104] It can be understood that, on the one hand, other structures can be installed at the narrower position to play the avoiding function, such as installing the pressure reducing valve seat 215, the joint 216 and the like; on the other hand, the gas can pass through the gap between the two gas storage cylinders in the previous row of gas storage cylinders to reach the next row of gas storage cylinders, Figure 13 The figure shows the general flow direction of the gas. In order to facilitate the description, taking the example of the previous row of gas storage cylinders including three gas storage cylinders and the next row of gas storage cylinders including two gas storage cylinders for description. Hot air flows into the first space 141 from the first opening 1311, part of the gas directly contacts the three gas storage cylinders of the first row, part of the gas flows to the second row of gas storage cylinders from the gap between the three gas storage cylinders of the first row, the second row of gas storage cylinders includes two gas storage cylinders, and each gas storage cylinder corresponds to the gap between the two gas storage cylinders of the first row of gas storage cylinders, thus the hot air can heat the two gas storage cylinders of the second row of gas storage cylinders through the gap. Repeating the above steps can realize heating the part of the gas storage cylinders located in each sub-space, or heating multiple gas storage cylinders in a sub-space.

[0105] According to one embodiment of the utility model, in the direction from the third side plate 133 to the fourth side plate 134, the ratio of the width size of the gap 144 to the length of the flow guide 2 is 1 / 20-1 / 12. For example, the width of the gap 144 is 2.55cm, and the length of the flow guide 2 is 37cm. In this embodiment, by designing the ratio of the width size of the gap 144 to the length of the flow guide 2 to be 1 / 20-1 / 12, for example, the ratio of the two is 1 / 12, 1 / 13, 1 / 14, 1 / 15, 1 / 16, 1 / 17, 1 / 18, 1 / 19 or 1 / 20, etc., not only is it convenient for gas circulation, but also it is beneficial to place more gas storage cylinders.

[0106] In some specific embodiments of the utility model, in the direction from the first side plate 131 to the second side plate 132, the height of the first space 141 is n times the height of the second space 142 or the third space 143, and n is not less than 1. That is, the height of the first space 141 is greater than the height of the second space 142 or the third space 143, and by designing a higher first space 141, it is convenient for gas to flow quickly from the first opening 1311 to the accommodation space 14, and by designing a lower second space 142 or third space 143, it is beneficial to prolong the heat retention time of the hot gas flow, ensuring the heat retention effect on the lower part of the gas storage cylinder.

[0107] It can be understood that the product can be diversified by selecting at least one of the above conditions, for example, the arrangement of multiple gas storage cylinders is satisfied alone, or the ratio of the width size of the gap 144 to the length of the flow guide 2 is satisfied alone, etc. The product can be adjusted and designed according to the product requirements, and the flexibility is strong.

[0108] The advantages of the gas supply device 100 of the present embodiment are described in detail below by taking the solid-state hydrogen storage device 3 used in the gas cylinder as an example. When the hot air with heat is conducted into the containing space 14 in which the solid-state hydrogen storage device 3 is installed, the solid-state hydrogen storage device 3 will absorb heat when releasing hydrogen to the outside, and the temperature drop in the containing space 14 will reduce the hydrogen release efficiency of the solid-state hydrogen storage device 3. Therefore, conducting the hot air into the containing space 14 can improve the hydrogen release efficiency of the solid-state hydrogen storage device 3. In the present embodiment, by using the solid-state hydrogen storage technology, the hydrogen release and absorption characteristics of certain substances and the heat exchange phenomenon accompanying the hydrogen release and absorption process can be utilized, and the solid-state hydrogen storage device 3 has the advantages of high safety and high volume density, which is beneficial to the application and development of hydrogen energy scenarios. Moreover, the gas supply device 100 of the present embodiment can use the heat generated by the fuel cell device 200 during operation to heat the solid-state hydrogen storage device 3, and has the advantages of uniform heating and good heat locking effect. In addition, by vertically placing the solid-state hydrogen storage device 3, and under the influence of gravity when the solid-state hydrogen storage device 3 is vertically placed, the solid-state hydrogen storage metal in the solid-state hydrogen storage device 3 is mainly in the middle and lower part of the solid-state hydrogen storage device 3. By uniformly heating the vertically placed solid-state hydrogen storage device 3 in multiple regions, it is beneficial to realize the stable and continuous release of hydrogen gas by the solid-state hydrogen storage device 3. It can be understood that, in the direction from the first side plate 131 to the second side plate 132, the height of the first space 141 is n times the height of the second space 142 or the third space 143, n is not less than 1, which is beneficial to ensure the heat locking effect on the middle and lower part of the solid-state hydrogen storage device 3.

[0109] Optionally, assuming along the direction from top to bottom, the plurality of flow guides 2 are defined as a first flow guide, a second flow guide, an m-1 flow guide, an m flow guide, the height of the sub-space between the first shell 11 and the first flow guide is H1, that is, the height of the first space 141 is H1; the height of the sub-space between the second shell 12 and the m flow guide is H2, that is, the height of the second space 142 is H2; the height of the sub-space between the m-1 flow guide and the m flow guide is H3, that is, the height of the third space 143 is H3. H1 is greater than H2 and H3. When the solid-state hydrogen storage device 3 is used, the solid-state hydrogen storage device 3 is filled with hydrogen storage alloy, the installation position of the first flow guide is not lower than the filling height of the hydrogen storage alloy in the solid-state hydrogen storage device 3, and is higher than the lower edge of the first opening 1311. At this time, the solid-state hydrogen storage device 3 is heated by the hot gas flow, that is, the hydrogen storage alloy in the solid-state hydrogen storage device 3 is heated, and the height of the first space 141 is designed to be the largest, the heights of the second space 142 and the third space 143 are smaller, and the height of the first space 141 is n times the height of the second space 142 and / or the third space 143, n is not less than 1, that is, n is greater than or equal to 1, for example, the height of the first space 141 is 1.1 times, 1.2 times, 1.3 times, 1.4 times, 1.5 times, 1.6 times, 1.7 times, 1.8 times, 2 times, 2.5 times, 2.8 times or 3 times the height of the second space 142 and the third space 143, etc. can make the hot gas to prolong the process path, prolong the residence time, and the heat locking effect is better, so that the efficiency of the hydrogen storage alloy during hydrogen release is higher.

[0110] Optionally, the height of the sub-space between the adjacent two flow guides 2 is the same, so that the flow rate of the hot air flowing through each layer of sub-space is more uniform.

Because the solid-state hydrogen storage device 3 will absorb heat when releasing hydrogen to the outside, the decrease in temperature in the accommodation space 14 will reduce the hydrogen release efficiency of the solid-state hydrogen storage device 3. Therefore, conducting the hot air generated during the operation of the fuel cell stack 201 into the accommodation space 14 can improve the hydrogen release efficiency of the solid-state hydrogen storage device 3. In addition, the hydrogen power system of the embodiment of the utility model can also solve the technical problem of low waste heat utilization rate of the fuel cell stack 201.
