[0013] Furthermore, the cover plate includes an upper cover and a side cover; the upper cover is detachably buckled on the top opening, and the side cover is detachably buckled on the side opening.

[0014] Furthermore, it also includes a limiting portion, which is arranged on the inner wall of the solid-state hydrogen storage space to fix the position of the hydrogen storage device in the solid-state hydrogen storage space.

[0015] Furthermore, the limiting portion includes a positioning groove; the positioning groove can be detachable or welded to the bottom wall of the solid hydrogen storage space.

[0016] Furthermore, the limiting portion includes a support plate, one end of which is fixed to the side wall of the solid hydrogen storage space, and the other end of which is connected to the hydrogen storage device to prevent the hydrogen storage device from shifting.

[0017] Furthermore, it also includes an upper baffle, which is sealed between the inner wall of the solid hydrogen storage space and the hydrogen storage device to prevent air leakage during the flow of air from the air inlet to the outlet.

[0018] Furthermore, a fan is installed in the first through opening and / or the second through opening.

[0019] Furthermore, the first through-hole is arranged opposite to the air inlet, and the second through-hole is arranged opposite to the air outlet.

[0021] Furthermore, it also includes an auxiliary power module, which is arranged in the auxiliary power module space.

[0022] The principle of this utility model is:

[0023] Taking into consideration the overall volume of the solid-state hydrogen storage-fuel cell power generation system, the inventors decided that the height of the hydrogen storage device is much greater than the heights of the air inlet and outlet. Therefore, the existing method of arranging the air inlet and outlet relative to each other on the same horizontal plane makes it difficult to ensure that the hot air flow entering the solid-state hydrogen storage space is evenly absorbed by the hydrogen storage device.

[0024] The present invention uses multiple partitions to separate the housing into a fuel cell space (same space as the BOP), a solid-state hydrogen storage space, and a control module space, all of which are independent and have through-holes, based on the height range of the hydrogen storage device. The fuel cell space and the control module space are arranged outside the solid-state hydrogen storage space, and the first through-hole between the fuel cell space and the solid-state hydrogen storage space and the second through-hole between the control module space and the solid-state hydrogen storage space are staggered along the height direction of the solid-state hydrogen storage space. The fuel cell space is provided with an air inlet, and the control module space is provided with an air outlet. The first through-hole and the second through-hole are not at the same height. When the fuel cell space is located below the control module space, the air inlet is located below the air outlet, and the first through-hole is located below the second through-hole. Air flows in through the air inlet, flows into the solid-state hydrogen storage space through the first through-hole, flows from bottom to top in the solid-state hydrogen storage space, fully contacts and exchanges heat with the hydrogen storage device in the solid-state hydrogen storage space, and then flows into the control module space through the second through-hole. After cooling the control module, the air is discharged through the air outlet. When the fuel cell space is located above the control module space, the air inlet is located above the air outlet, and the first through-port is located below the second through-port: the air flows in through the air inlet, flows into the solid hydrogen storage space through the first through-port, flows from top to bottom in the solid hydrogen storage space, and after sufficient contact and heat exchange with the hydrogen storage device in the solid hydrogen storage space, flows into the control module space through the second through-port, cools the control module, and then discharges from the air outlet.

[0025] In the present invention, the fuel cell space and the control module space are both arranged outside the solid-state hydrogen storage space along the height direction of the solid-state hydrogen storage device, and are both connected to the solid-state hydrogen storage space. The hot air flow entering the solid-state hydrogen storage space flows along the height direction of the hydrogen storage device. During the flow of the air flow, the heat flow generated by the fuel cell is absorbed by the hydrogen storage device in the solid-state hydrogen storage space to the maximum extent, and the air flow cooled by the hydrogen storage device can further cool the control module; the air inlet and the air outlet are not at the same height, and the first through-port and the second through-port are not at the same height, so that the long-range flow of the heat flow generated by the fuel cell inside the box is maximized, so that the heat is maximized and the heat exchange efficiency of the hydrogen storage device is effectively improved.

[0026] The present invention also provides an auxiliary power module space for placing the auxiliary power module, which provides multiple functions such as starting / buffer charging for the solid-state hydrogen storage fuel cell power generation system.

[0027] The utility model has the following advantages over the prior art:

[0028] 1. The solid-state hydrogen storage fuel tank of the present invention has a compact overall structure. A partition is used to separate the interior of the battery box into a fuel cell space, a control module space, and a solid-state hydrogen storage space. A first through-hole is provided between the fuel cell space and the solid-state hydrogen storage space, and a second through-hole is provided between the control module space and the solid-state hydrogen storage space. The first through-hole and the second through-hole are staggered along the height direction of the solid-state hydrogen storage space to maximize the long-range flow of the heat flow generated by the fuel cell within the box, thereby maximizing the utilization of heat and effectively improving the heat exchange efficiency of the hydrogen storage device. The fuel cell space and the solid-state hydrogen storage space, as well as the control module space and the solid-state hydrogen storage space, are connected, and form an air duct with the air inlet and outlet. The hot air flow entering the solid-state hydrogen storage space flows along the height direction of the hydrogen storage device, so that the heat flow generated by the fuel cell is absorbed by the hydrogen storage device in the solid-state hydrogen storage space to the maximum extent. The air flow cooled by the hydrogen storage device can further cool the control module, further improving the heat reuse rate.

[0029] 2. The solid-state hydrogen storage fuel cell box of the present invention is also provided with an auxiliary power module space for installing the auxiliary power module to achieve rapid start-up of the fuel cell power generation system.

[0030] 3. The solid-state hydrogen fuel cell box of this utility model has an openable top cover, side covers, and opening for easy internal maintenance. The solid-state hydrogen storage space is provided with a positioning groove and support plate for securing the hydrogen storage device. An upper baffle is also provided to seal the upper end of the hydrogen storage device with the inner wall of the solid-state hydrogen storage space, preventing air leakage during airflow through the solid-state hydrogen storage space.

[0031] 4. The hydrogen power system of this utility model utilizes the aforementioned solid-state hydrogen storage fuel cell box. The fuel cell, BOP module, hydrogen storage device, and control module are located within the box.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] It should be noted that, in the description of the present invention, the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0045] In addition, it should be understood that for the convenience of description, the sizes of the various components shown in the drawings are not drawn according to the actual scale.

[0046] It should be noted that like numbers and letters represent similar items in the following figures, so once an item is defined or described in one figure, it will not need to be further discussed and described in detail in the description of the subsequent figures.

[0047] Example 1:

[0048] The following example only takes the case where the air inlet and outlet are located on the same projection plane:

[0049] like Figures 1 to 3As shown, a solid-state hydrogen storage fuel cell box 1000 includes: a shell 1100, wherein the interior of the shell 1100 is separated into a fuel cell space 1110, a solid-state hydrogen storage space 1120 and a control module space 1130 by a partition, wherein a first through-hole 1102 is provided between the fuel cell space 1100 and the solid-state hydrogen storage space 1120, and a second through-hole 1103 is provided between the control module space 1130 and the solid-state hydrogen storage space 1120, the first through-hole 1103 and the second through-hole 1103 are staggered along the height direction of the solid-state hydrogen storage space 1120, and the midline of the solid-state hydrogen storage space 1120 along the height direction is perpendicular to the first plane and passes through the fuel cell space The projections of the first straight line 1100 and the second straight line passing through the control module space 1130 on the first plane have an angle of 0° to 180°, and the first straight line and the second straight line are both perpendicular to the center line of the solid-state hydrogen storage space 1120 along the height direction. An air inlet 1101 is opened on one side of the fuel cell space 1110, and an air outlet 1104 is opened on one side of the control module space 1130, so that an air duct is formed between the fuel cell space 1110, the solid-state hydrogen storage space 1120 and the control module space 1130. The airflow entering from the air inlet 1101 passes through the fuel cell space 1110, the solid-state hydrogen storage space 1120 and the control module space 1130 in sequence, and is discharged through the air outlet 1104.

[0050] In this embodiment, the projections of the first straight line and the second straight line on the first plane have an angle of 0°: the first through-hole 1103 and the second through-hole 1103 are staggered along the height direction of the solid-state hydrogen storage space 1120, wherein, when the fuel cell space is located below the control module space, the air inlet is located below the air outlet, and similarly, the first through-hole 1103 is located below the second through-hole 1103: the air flow flows in through the air inlet, flows into the solid-state hydrogen storage space through the first through-hole, flows from bottom to top in the solid-state hydrogen storage space, and after sufficient contact and heat exchange with the hydrogen storage device in the solid-state hydrogen storage space, flows into the control module space through the second through-hole, cools the control module, and is discharged from the air outlet. When the fuel cell space is located above the control module space, the air inlet is located above the air outlet, and similarly, the first through-hole 1103 is located above the second through-hole 1103: air flows in through the air inlet, flows into the solid hydrogen storage space through the first through-hole, flows from top to bottom within the solid hydrogen storage space, fully contacts and exchanges heat with the hydrogen storage device within the solid hydrogen storage space, then flows into the control module space through the second through-hole, cools the control module, and then exits through the air outlet. The hot air flow entering the solid hydrogen storage space flows along the height direction of the hydrogen storage device. During the flow of air, the heat generated by the fuel cell 1 is absorbed by the hydrogen storage device 3 in the solid hydrogen storage space 1120 to the maximum extent, and the air flow cooled by the hydrogen storage device 3 can further cool the control module 4. The first through-hole 1103 and the second through-hole 1103 are staggered along the height direction of the solid hydrogen storage space 1120 to maximize the long-range flow of the heat generated by the fuel cell within the housing, thereby maximizing heat utilization and effectively improving the heat exchange efficiency of the hydrogen storage device.

[0051] The control module space 1130 is placed above the fuel cell space 1110, facilitating maintenance. Furthermore, the high-temperature cooling airflow generated by the heat dissipation of the fuel cell 1 in the fuel cell space 1110 passes through the hydrogen storage device in the solid-state hydrogen storage space 1120 for heat exchange, lowering its temperature before passing through the control module. This reduces the number of heat dissipation components in the control module, further reducing the overall cost of the power generation system.

[0052] The shell 1100 in this embodiment also includes a cover plate. The top of the shell has a top opening connected to the solid hydrogen storage space, and the side of the shell has a side opening. The cover plate can be detachably fastened to the top opening and the side opening. The air inlet and the air outlet are both provided on the cover plate or the shell, or the air inlet and the air outlet are respectively provided on the cover plate and the shell. In this embodiment, the cover plate is formed by connecting the upper cover 1200 and the side cover 1300 or forming the upper cover 1200 and the side cover 1300 as a whole. The cover plate is detachably installed with the shell 1100. Open the cover plate and perform maintenance and repair on the interior of the battery box through the top opening and the side opening. In this embodiment, the air inlet and the air outlet are both provided on the shell, the first through-hole is provided opposite to the air inlet, and the second through-hole is provided opposite to the air outlet. In other embodiments, the air inlet and the air outlet may be provided on the cover plate opposite to the side opening. In actual operating conditions, the following scenarios are also possible: the air inlet is located on the housing, and the air outlet is located on the cover plate opposite the side opening; or the air inlet is located on the cover plate opposite the side opening, and the air outlet is located on the housing, that is, the air inlet and air outlet are not on the same projected plane. Placing the air inlet and air outlet on adjacent or opposing planes can reduce the impact of the hot airflow discharged from the air outlet on the temperature of the airflow entering the air inlet. Regardless of the configuration method used, it is sufficient to ensure that the airflow flows in through the air inlet, flows through the fuel cell space, the control module space, the solid-state hydrogen storage space, and then out through the air outlet.

[0053] In another embodiment, the cover plate can be divided into an upper cover 1200 and a side cover 1300; the upper cover 1200 is removably mounted to the top opening, and the side cover 1300 is removably mounted to the side opening. Separating the cover plates allows for targeted maintenance of the solid-state hydrogen storage space 1120 without opening the side covers, facilitating easy access. The structure of this battery box 1000 ensures that the solid-state hydrogen storage fuel cell power generation system housed therein remains sealed, effectively preventing dust and water.

[0054] This embodiment also includes a limiting portion, which is arranged on the inner wall of the solid-state hydrogen storage space 1120 and is used to fix the hydrogen storage device 4 inside the solid-state hydrogen storage space 1120 to prevent the hydrogen storage device from tipping over and ensure the stability of the entire system. In a specific embodiment, the limiting portion can be a positioning groove 1105; the positioning groove 1105 can be detachable or welded to the bottom wall of the solid-state hydrogen storage space. The position of the hydrogen storage device 4 is limited in the positioning groove 1105. In addition, the limiting portion can also be a support plate 1106, one end of the support plate 1106 is fixed to the side wall of the solid-state hydrogen storage space 1120, and the other end is connected to the hydrogen storage device 3, and the other end of the support plate 1106 is close to the outer contour of the hydrogen storage device 3 (such as Figure 3 and Figure 4As shown, the hydrogen storage device is cylindrical, and the other end of the support plate has a semi-arc-shaped opening for engaging with the outer wall of the hydrogen storage device, thereby engaging with the hydrogen storage device and preventing the hydrogen storage device from shifting. In other embodiments, the limiting portion can also be provided by a positioning groove 1105 and a support plate 1106 to further improve the stability of the hydrogen storage device 3.

[0055] An upper baffle 1107 is also provided within the solid-state hydrogen storage space 1120 to seal the surrounding walls of the hydrogen storage device 3, ensuring that airflow from the air inlet 1101 to the air outlet 1104 does not leak. The hydrogen storage device 3 can be removed from and inserted into the solid-state hydrogen storage device space 1120 through the opening and top of the upper baffle 1107. The opening of the upper baffle 1107 is sealed by an interference fit with the sidewalls of the hydrogen storage device 3 using a sealing ring or rubber seal.

[0056] A first through-port 1102 is provided on one side of the fuel cell space 1110, and a second through-port 1103 is provided on one side of the control module space 1130; an air duct is formed between the air inlet 1101, the first through-port 1102, the second through-port 1103 and the air outlet 1104, so that the heat flow generated by the fuel cell is absorbed by the hydrogen storage device in the solid-state hydrogen storage device to the maximum extent. A fan is provided inside the housing 1100 so that the air flow can flow smoothly in a single direction from the air inlet 1101 to the air outlet 1104, preventing the air flow from flowing back. The fan can be installed in the first through-port 1102 and / or the second through-port 1103. Depending on the actual working conditions, fans are installed in both the first through-port and the second through-port, or fans are installed only in the first through-port or the second through-port.

[0057] In this embodiment, an auxiliary power module space 1140 is further separated within the housing 1100, and the auxiliary power module space 1140 is isolated from the fuel cell space 1110, the control module space 1130, and the solid-state hydrogen storage space 1120. The auxiliary power module space 1140, the fuel cell space 1110 (which is in the same space as the BOP), the solid-state hydrogen storage device space 1120, and the control module space 1130 can be spatially located on the side of any one of the three spaces or on the sides of two adjacent spaces. Alternatively, the auxiliary power module space 1140 can be housed within one of the fuel cell space 1110, the control module space 1130, and the solid-state hydrogen storage space 1120. Specifically, a third straight line passing through the auxiliary power module space is perpendicular to the centerline of the solid-state hydrogen storage space along the height direction, and is parallel to or at an angle to the projection of the first straight line or the second straight line on the first plane.

[0058] The auxiliary power module space 1140 accommodates the auxiliary power module 5, which may specifically be a supercapacitor, a lithium battery module, a nickel-metal hydride battery module, a lead-acid battery module, or the like. In some embodiments, when the auxiliary power module 5 in the auxiliary power module space 1140 requires repair and maintenance, repair and maintenance can be performed by simply opening the side cover 1300 or the cover mounted on the housing 1100. In other embodiments, to facilitate repair and maintenance of the auxiliary power module 5, the auxiliary power module space 1140 has an independent, openable opening. The provision of the opening allows for repair and maintenance of the auxiliary power module 5 without opening the side cover 1300 or the cover to expose the internal components of the solid-state hydrogen storage fuel cell power generation system, making repair and maintenance quick and convenient.

[0059] like Figure 4 As shown, a hydrogen power system includes the above-mentioned solid-state hydrogen storage fuel cell box 1000, as well as a fuel cell 1, a BOP (Balance of Plant) module 2, a hydrogen storage device 3, a control module 4, and an auxiliary power module 5. The fuel cell 1 and BOP module 2 are arranged vertically in a fuel cell space 1110, the hydrogen storage device 3 is arranged in a solid-state hydrogen storage space 1120, the control module 4 is arranged in a control module space 1130, and the auxiliary power module 5 is arranged in an auxiliary power module space 1140. The BOP module 2 is connected to the fuel cell 1 and provides hydrogen to the hydrogen storage device 3. The fuel cell 1 and the BOP module 2 are both signal-connected to the control module 4, and the auxiliary power module is signal-connected to the control module. The hydrogen storage device 3 provides hydrogen via the BOP module 2, which acts as an intermediate auxiliary module to control the hydrogen and oxygen required for the fuel cell 1 reaction. The fuel cell 1 converts the hydrogen and oxygen into electrical energy / heat energy and produces water. The control module 4 is used to provide overall control of the fuel cell 1 and the BOP module 2. The auxiliary power module 5 provides multiple functions such as starting / buffer charging for the solid-state hydrogen storage fuel cell power generation system.

[0060] Compared with the existing technology, this hydrogen power system integrates the control module 4 and the auxiliary power module 5 into the battery box. The overall structure is compact and has an air duct structure that guides the fuel cell to generate heat flow, so that the heat is more evenly absorbed by the hydrogen storage device. By setting the auxiliary power module 5 as an early auxiliary starting power supply, when the solid-state hydrogen storage-fuel cell power generation system is unable to provide electricity for the normal operation of the hydrogen two-wheeled vehicle in the early stage, the normal operation of the hydrogen two-wheeled vehicle can be achieved by starting the auxiliary power supply. By adopting a wrapping structure, the height of the air inlet 1101 is set to be not in a straight line with the height of the air outlet 1104, and the first through-port and the second through-port are staggered along the height direction of the hydrogen storage device. This setting is more conducive to increasing the flow path of hot air, and the airflow cooled by the hydrogen storage device 3 can also cool the control module 4, further improving the heat recycling rate.

[0061] like Figure 5 As shown below, the structure of the housing 1100 is taken as an example in which the control module space 1130 and the fuel cell space 1110 are arranged vertically opposite each other along the height direction of the solid hydrogen storage space 1120:

[0062] In this structural embodiment, the airflow in the solid-state hydrogen storage fuel cell box flows clockwise. The fuel cell 1 is located in the fuel cell space 1110 in the shell 1100. In the fuel cell space 1110, the BOP module 2 is directly connected to the fuel cell 1. The BOP module 2 is located below the fuel cell 1 to assist the fuel cell 1 in its operation. The external airflow enters the fuel cell space 1110 through the air inlet 1101 on the side of the fuel cell space 1110. The hydrogen storage device 3 is located in the solid-state hydrogen storage space 1120. The solid-state hydrogen storage space 1120 is spatially located on the side of the fuel cell space 1110. The solid-state hydrogen storage device 3 provides hydrogen through the BOP module 2. The solid-state hydrogen storage device 3 is spatially close to the fuel cell 1, so that the high-temperature hot air flow generated by the fuel cell 1 can flow directly through the first through port 1102 under the action of the fan and transmit The heat of the high-temperature hot air flow is transmitted to the hydrogen storage 3, and the heat of the high-temperature hot air flow is absorbed by the hydrogen storage 3, which is conducive to the release of hydrogen from the hydrogen storage 3. The control module 4 is located in the control module space 1130, which is spatially located above the fuel cell space 1110 and to the side of the solid-state hydrogen storage space 1120. After the hydrogen storage 3 absorbs the heat of the high-temperature hot air flow, the air flow temperature is reduced. The reduced temperature air flow can directly flow into the control module space 1130 through the second through-hole 1103 under the action of the fan, cooling the control module 4 that generates heat during operation to prevent the control module 4 from malfunctioning due to overheating. At the same time, the reduced temperature air flow is reheated in the control module space 1130 where the control module 4 is located, and finally flows out from the air outlet 1104. This structural arrangement can ensure the maximum utilization of the energy carried by the air flow, enhance the reliability of the system heat dissipation, further improve the system stability, and also improve the system energy utilization rate.

[0063] The wraparound structure, which sets the height of the air inlet 1101 lower than that of the air outlet 1104, is more conducive to the circulation of hot air and further improves the heat recycling rate. In addition, placing the control module above the fuel cell is more convenient for maintenance.

[0064] Example 2:

[0065] This embodiment is the same as embodiment 1 except for the following technical features:

[0066] like Figure 6As shown, the structure of the shell 1100 in this embodiment is based on the fuel cell space 1110 and the control module space 1130 being arranged vertically opposite each other along the height direction of the solid-state hydrogen storage space 1120. The projections of the first straight line and the second straight line on the first plane have an angle of 0°. The air flow in the solid-state hydrogen storage fuel cell box flows counterclockwise, and the air inlet 1101 and the air outlet 1104 are arranged on the same side with an enveloping structure, which is more conducive to increasing the flow path of hot air and further improving the heat recycling rate.

[0067] Example 3:

[0068] This embodiment is the same as embodiment 1 except for the following technical features:

[0069] like Figure 7 As shown, in this embodiment, along the height direction of the solid-state hydrogen storage space, the fuel cell space is located below the control module space, and the projections of the first straight line and the second straight line on the first plane form a 90° angle, that is, there is a 90° angle in space between the fuel cell space 1110 and the control module space 1130. At this time, the air inlet is located below the air outlet, and the first through-hole is located below the second through-hole. The air flows in through the air inlet, flows into the solid-state hydrogen storage space through the first through-hole, flows from bottom to top in the solid-state hydrogen storage space, and after sufficient contact and heat exchange with the hydrogen storage device in the solid-state hydrogen storage space, flows into the control module space through the second through-hole, cools the control module, and is discharged from the air outlet. Through the above improvements, the structural diversity of the battery box can be improved, making it suitable for different usage scenarios.

At this time, the air inlet is located above the air outlet, and the first through-hole is located above the second through-hole: the air flows in through the air inlet, flows into the solid-state hydrogen storage space through the first through-hole, flows from top to bottom in the solid-state hydrogen storage space, and after sufficient contact and heat exchange with the hydrogen storage device in the solid-state hydrogen storage space, flows into the control module space through the second through-hole, cools the control module, and then discharges from the air outlet. Through the above improvements, the structural diversity of the battery box can be improved, making it suitable for different usage scenarios.

The air flows in through the air inlet, flows into the solid-state hydrogen storage space through the first through-hole, flows from bottom to top in the solid-state hydrogen storage space, and after sufficient contact and heat exchange with the hydrogen storage device in the solid-state hydrogen storage space, flows into the control module space through the second through-hole, cools the control module, and is then discharged from the air outlet. Through the above improvements, the structural diversity of the battery box can be improved, making it suitable for different usage scenarios.
