[0002] In the prior art, there are two main structures of solid-state hydrogen storage fuel cell power generation systems. One structure is that the air inlet and the air outlet are connected, and the fuel cell, the stack controller and the hydrogen storage device are stored in a shell, which is a closed structure; the other structure is that the air inlet and the air outlet are connected, the fuel cell is stored in an independent cavity, and only the part of the hydrogen storage device that needs to absorb heat is stored in the box, which is a semi-closed structure.

[0003] However, both structures use a fan to guide air to flow almost straight from the air inlet to the air outlet, so as to utilize the heat generated by the fuel cell to exchange heat with the hydrogen storage bottle. Such an air outlet through-type structure can only achieve good heat exchange for the part of the hydrogen storage bottle facing the air inlet or the air outlet, and the rest of the hydrogen storage bottle cannot be fully heat exchanged, resulting in a low actual utilization rate of the heat flow generated by the fuel cell.

The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0031] Please refer to Figure 1-8The present application discloses a fuel cell power generation system bracket, including a frame 1. The frame 1 includes a front plate and a rear plate arranged opposite to each other, and a partition 2 is arranged in the frame. The partition 2 divides the interior of the frame 1 into a hydrogen storage bottle installation space 3 and a fuel cell installation space 5, and the hydrogen storage bottle installation space is located on the side of the fuel cell installation space facing the rear plate. An air inlet 7 is provided on the partition 2. The air inlet 7 connects the hydrogen storage bottle installation space 3 and the fuel cell installation space 5. An air inlet 6 is provided on the portion of the front plate opposite to the fuel cell, and an air outlet 8 is provided on the portion of the rear plate opposite to the hydrogen storage bottle installation space. The fuel cell installation space 5 is connected to the outside through the air inlet 6. The hydrogen storage bottle installation space 3 is connected to the outside through the air outlet 8. The hydrogen storage bottle installation space 3 is used to install a hydrogen storage bottle group. The hydrogen storage bottle group includes at least two hydrogen storage bottles 4. The hydrogen storage bottles 4 in the hydrogen storage bottle group are arranged side by side along the same straight line, and the bottle bodies of two adjacent hydrogen storage bottles 4 are tightly fitted. The hydrogen storage bottle group is blocked between the air inlet 7 and the air outlet 8, forcing the airflow to bypass the hydrogen storage bottle group before flowing out from the air outlet 8. A through hole 301 for installing the hydrogen storage bottle group into the hydrogen storage bottle installation space 3 is provided on the upper side of the frame 1. The area of ​​the air inlet 6 is greater than or equal to the area of ​​the air inlet 7, and the area of ​​the air inlet 7 is greater than the area of ​​the air outlet 8.

[0032] The fuel cell power generation system support of the present application also includes an upper sealing cover and a bottom sealing seat. Figure 1-8 The upper sealing cover and the bottom sealing seat are not shown. The bottom sealing seat can close the opening of the through hole 301 on the lower side of the frame 1, and support the hydrogen storage bottle group installed in the hydrogen storage bottle installation space 3. Its shape can be designed accordingly according to the installation position of the fuel cell power generation system bracket. For the upper sealing cover, in actual use, the upper sealing cover can be a component installed separately on the frame 1, or it can be a component connected to the frame 1 after the frame 1 is installed in place. For example, when the fuel cell power generation system bracket of the present application is used in an electric two-wheeled vehicle, the fuel cell power generation system is installed below the seat, and the seat can be used as the upper sealing cover. The upper sealing cover can seal the upper opening of the through hole 301.

[0033] The implementation principle of the fuel cell power generation system bracket of the present application is: the airflow enters the fuel cell installation space 5 from the air inlet 6 and exchanges heat with the fuel cell. Since the flow area of ​​the air inlet 7 is smaller than the flow area of ​​the air inlet 6, the flow rate of the airflow in the fuel cell installation space 5 is reduced, and it can fully exchange heat with the fuel cell. After the airflow exchanges heat with the fuel cell, it enters the hydrogen storage bottle installation space 3 through the air inlet 7. Since the flow area of ​​the air outlet 8 is smaller than the flow area of ​​the air inlet 7, the flow rate of the airflow in the hydrogen storage bottle installation space 3 is further reduced, and then fully exchanges heat with the hydrogen storage bottle 4. In addition, since the bottles of the two adjacent hydrogen storage bottles 4 are closely fitted and the hydrogen storage bottle group is blocked between the air inlet 7 and the air outlet 8, the airflow is forced to flow only along the circumferential and / or axial direction of the hydrogen storage bottle 4, and cannot flow between the bottles of the two adjacent hydrogen storage bottles 4, and finally discharged from the air outlet 8. In this way, the utilization rate of the heat released by the fuel cell can be improved, and the effect of releasing hydrogen by the hydrogen storage bottle 4 can be improved.

[0034] Among them, the reason for setting up no less than two hydrogen storage bottles 4 is that, when the total amount of hydrogen is the same, the hydrogen can be divided into two or more hydrogen storage bottles 4, which can reduce the height of the hydrogen storage bottle 4 in the axial direction thereof, thereby facilitating the reduction of the overall height of the fuel cell power generation system bracket, thereby reducing the overall height of the entire hydrogen-using device, and a single hydrogen storage bottle 4 is relatively light in weight, and there is no strength requirement for personnel who replace the hydrogen storage bottle.

[0035] It should be noted that, under the same implementation principle, the frame 1 is projected along the axial direction of the hydrogen storage bottle 4, and its projection shape on the plane can be a polygon, an ellipse or a circle. When the shape of the frame 1 changes, the relative positions of the front plate and the rear plate do not change, and the shapes of the front plate and the rear plate change accordingly. For example, the shapes of the front plate and the rear plate can be flat or arc-shaped. In order to clearly demonstrate the implementation principle of the present application, the following is a specific explanation using the example that the frame 1 is in the shape of a cuboid, the front plate and the rear plate are both flat, that is, the projection of the frame 1 on the plane along the axial direction of the hydrogen storage bottle 4 is a rectangle.

[0036] For details, please refer to Figure 1-3 , the frame 1 is in the shape of a rectangular parallelepiped. Figure 1 The side of the middle frame 1 where the air inlet 6 is located is the front plate, and the side of the frame 1 opposite to the front plate where the air outlet 8 is located is the rear plate of the frame 1. In this way, the fuel cell installation space 5 is a space formed from the front plate along the front-to-back direction of the frame 1 to the partition 2. The shape of the fuel cell installation space 5 is adapted to the shape of the fuel cell to be accommodated therein. In this embodiment, the shape of the fuel cell installation space 5 is a rectangular parallelepiped. The opening of the fuel cell installation space 5 on the front plate is the air inlet 6.

[0037] The hydrogen storage bottle installation space 3 is a space formed from the rear plate along the front-to-back direction of the frame body 1 to the partition 2. Figure 4 and Figure 5 Taking the orientation shown in as an example, the hydrogen storage bottles 4 of the hydrogen storage bottle group are arranged side by side along the left and right direction of the frame 1. The through hole 301 is located directly above the hydrogen storage bottle installation space 3. The through hole 301 penetrates the upper side of the frame 1 from top to bottom, so that the hydrogen storage bottle 4 can be placed in the hydrogen storage bottle installation space 3 through the through hole 301.

[0038] More specifically, in order to improve the stability of the hydrogen storage bottle 4 after it is placed in the hydrogen storage bottle installation space 3, a partition 302 is formed on the inner wall of the through hole 301. The inner wall of the through hole 301 is a wall surface formed after the through hole 301 passes through the upper and lower sides of the frame 1, so the through hole 301 includes the inner wall on the upper side of the frame 1 and the inner wall on the lower side of the frame 1, and the structures of the two parts of the inner wall are exactly the same, that is, a partition 302 is provided on each part of the inner wall. The partition 302 divides the through hole 301 into a plurality of circular holes 303. The number of circular holes 303 is the same as the number of hydrogen storage bottles 4 placed in the hydrogen storage bottle installation space 3. Two adjacent circular holes 303 are connected, so that each circular hole 303 can just accommodate the body of a hydrogen storage bottle 4, and the bodies of two adjacent hydrogen storage bottles 4 can still fit tightly.

[0039] The central axis of the air inlet 6 is parallel to or intersects with the central axis of the air inlet 7 in space, and the central axis of the air inlet 6 is parallel to or intersects with the central axis of the air outlet 8 in space. That is, the air inlet 6, the air inlet 7, and the air outlet 8 can be directly opposite, can be obliquely opposite, or can be connected but not opposite, and the specific arrangement method depends on the shape of the frame 1.

[0040] The number of air outlets 8 can be one, two or more. In one embodiment of the present application, the number of air outlets 8 is one, the air inlet 6 is close to the upper edge of the side where it is located (the top of the frame 1), and the air outlet 8 is close to the lower edge of the side where it is located (the bottom of the frame 1). Alternatively, the air inlet 6 is close to the lower edge of the side where it is located, and the air outlet 8 is close to the upper edge of the side where it is located, extending the flow path of the airflow in the frame 1. In other words, the air inlet 6 and the air outlet 8 should be as far away from each other as possible in the up and down directions of the frame 1 (i.e., the axial direction of the hydrogen storage bottle 4) without changing the side where they are located, so as to effectively extend the flow path of the airflow in the frame 1, so as to maximize the use of heat, and effectively improve the heat exchange efficiency of the hydrogen storage bottle 4. Moreover, at this time, the central axis of the air outlet 8 is located between the two air outlets 8, and at this time, the central axis of the air inlet 6 is collinear or close to the central axis of the air outlet 8, so as to extend the flow path of the airflow in the frame 1. The situation when the number of the air outlets 8 is three or more is the same as or similar to the situation when the number of the air outlets 8 is two, but no matter how many air outlets 8 there are, the sum of their total areas must be smaller than the area of ​​the air inlet 7.

[0041] In addition, the air outlet 8 is centrally symmetrical to the overall width of the hydrogen storage bottle group in the left-right direction of the frame 1 (the width direction of the frame 1 ), or the air outlet 8 is centrally symmetrical to the overall width of the frame 1 in the width direction.

[0042] Please refer to Figure 2 In this embodiment, the number of air outlets 8 is two, and the sum of the areas of the two air outlets 8 is smaller than the area of ​​the air inlet 7. One of the two air outlets 8 is close to the upper edge of its side, and the other is close to the lower edge of its side. The two air outlets 8 are aligned in the up and down direction of the frame 1. When the number of air outlets 8 is two, after the airflow enters the hydrogen storage bottle installation space 3 from the air inlet 7, it flows out from the two air outlets 8 respectively.

[0043] Figure 4-7 Specifically shows the flow path of the airflow in the frame 1 when the number of the air outlets 8 is two, Figure 5-7 The arrows in the figure represent the flow path and direction of the airflow. Figure 4-7 It can be clearly seen that the airflow first enters the fuel cell installation space 5 from the air inlet 6, and then enters the hydrogen storage bottle installation space 3 through the air inlet 7 on the partition 2. In the hydrogen storage bottle installation space 3, since the two hydrogen storage bottles 4 are tightly fitted together, the airflow cannot flow between the two hydrogen storage bottles 4, and can only be split and bypass the two hydrogen storage bottles 4 along the circumference of the two hydrogen storage bottles 4 before merging, and finally flow out of the hydrogen storage bottle installation space 3 from two air outlets 8. Such a setting can effectively utilize space, maximize wind resistance, and achieve the longest airflow path while allowing the airflow to evenly cover the entire hydrogen storage bottle 4 with heat, thereby maximizing heat utilization.

[0044] More specifically, in order to ensure that the flow velocity of the airflow in the frame 1 can be reduced and the flow resistance is not too large, the total area of ​​the air outlet 8 is 40%-60% of the area of ​​the air inlet 6, for example, it can be 40%, 45%, 50%, 55%, 60%. Preferably, in this embodiment, the total area of ​​the air outlet 8 is 50% of the area of ​​the air inlet 6. By optimizing the ratio between the total area of ​​the air outlet 8 and the area of ​​the air inlet 6, the three methods of lengthening the airflow path, increasing the flow resistance of the airflow, and a smaller area of ​​the air outlet 8 are combined, which is more conducive to slowing down the flow of the airflow, so that the heat in the airflow is fully released in the hydrogen storage bottle installation space 3. In addition, after the heat of the airflow is released in the hydrogen storage bottle installation space 3, the temperature of the exhaust gas discharged from the air outlet 8 is close to or equal to the room temperature, and the safety is better.

[0045] Please refer to Figure 8 During the use of the fuel cell power generation system bracket, the fuel cell and its control system need to be repaired and maintained. In order to enable the staff to conveniently repair and maintain the fuel cell and its control system, a maintenance window 9 is opened on one side of the frame 1. The maintenance window 9 is connected to the fuel cell installation space 5. A side cover 91 is installed at the maintenance window 9. The side cover 91 can close the maintenance window 9. The side cover 91 and the frame 1 are detachably connected or movably connected.

[0046] Specifically, the maintenance window 9 is located on the right side of the frame 1. The inner wall of the maintenance window 9 is formed with a groove whose cross-sectional shape matches the edge shape of the side cover 91, and the side cover 91 can be inserted into the groove and close the maintenance window 9. In another embodiment of the present application, the side cover 91 is movably installed at the maintenance window 9 through a hinge, and a locking device is provided on the frame 1 near the maintenance window 9 to limit the side cover 91 to ensure that it can close the maintenance window 9 without loosening.

[0047] More specifically, a sealing structure such as a sealing strip or a sealing adhesive is provided between the maintenance window 9 and the side cover 91 to prevent the airflow in the fuel cell installation space 5 from leaking out from the gap between the maintenance window 9 and the side cover 91 .

[0048] Please refer to Figure 1 A lithium battery installation space 10 is formed on the frame 1 for accommodating a lithium battery. The lithium battery has the functions of assisting the start-up of the fuel cell and serving as an emergency power source when the fuel cell is damaged. Specifically, the lithium battery installation space 10 is formed from the upper side of the frame 1 downwardly and is a rectangular space. The lithium battery installation space 10 is located above the fuel cell installation space 5, but is not connected to the fuel cell installation space 5. The lithium battery installation space 10 does not invade the hydrogen storage bottle installation space 3 in the front and rear directions of the frame 1, forming a avoidance so that there is enough space in the hydrogen storage bottle installation space 3 to install the hydrogen storage bottle 4.

[0049] Please continue to refer to Figure 1 The frame 1 is provided with an electrical connection port 11 and a gas connection port 12. The electrical connection port 11 is used to electrically connect the fuel cell and lithium battery installed in the frame 1 to the outside. The gas connection port 12 is used to connect the hydrogen storage bottle 4 installed in the frame 1 to the outside. Figure 1 The above is only an example of a feasible arrangement of the electrical connection port 11 and the gas connection port 12. In actual use, the position, quantity and shape of the electrical connection port 11 and the gas connection port 12 can be arranged according to actual use requirements.

[0050] The implementation principle of the fuel cell power generation system bracket of the present application is as follows: the airflow enters the fuel cell installation space 5 from the air inlet 6 and exchanges heat with the fuel cell. Since the flow area of ​​the air inlet 7 is smaller than the flow area of ​​the air inlet 6, the flow rate of the airflow in the fuel cell installation space 5 is reduced, and sufficient heat exchange with the fuel cell can be achieved. After the airflow exchanges heat with the fuel cell, it enters the hydrogen storage bottle installation space 3 through the air inlet 7. Since the flow area of ​​the air outlet 8 is smaller than the flow area of ​​the air inlet 7, the flow rate of the airflow in the hydrogen storage bottle installation space 3 is further reduced, and then sufficient heat exchange with the hydrogen storage bottle 4 is achieved. Moreover, since the bodies of the two adjacent hydrogen storage bottles 4 are tightly fitted, the airflow can only flow around the bodies of the two hydrogen storage bottles 4 to the air outlet 8, and cannot flow between the bodies of the two adjacent hydrogen storage bottles 4, and finally discharged from the air outlet 8.

[0051] The fuel cell power generation system bracket of the present application sets the air inlet 6 and the air outlet 8 at different positions, that is, the air outlet 8 is respectively located near the upper side and / or the lower side of the hydrogen storage bottle 4, so as to maximize the flow of the heat flow generated by the fuel cell in the fuel cell power generation system bracket. The total area of ​​the air outlet 8 is 40%-60% of the area of ​​the air inlet 6, which reduces the air flow velocity, thereby maximizing the utilization of heat and effectively improving the heat exchange efficiency of the hydrogen storage bottle 4. In addition, the present application also has the advantages of simple structure and convenient production.

[0052] At the same time, the fuel cell power generation system bracket of the present application can well integrate the entire fuel cell power generation system, and can add an upper sealing cover and a bottom sealing seat structure on the upper part, and by adjusting the upper sealing cover and / or the bottom sealing seat, it can match the requirements of various shapes and sizes of hydrogen storage bottles 4. At the same time, the integrated structure can minimize the volume of the entire fuel cell power generation system.

[0053] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
