Abstract
Description
Technical Field
[0001] This application relates to the field of energy storage technology, and more specifically, to a baffle assembly, a flow guiding module, and a hydrogen power generation system. Background Technology
[0002] Hydrogen energy is a clean energy source for the 21st century. One important application area of hydrogen energy is in the "hydrogen-electricity" field. Hydrogen energy can be stored in various ways, such as high-pressure gaseous state, low-temperature liquid state, organic liquid state, and metallic (non-metallic) solid state. Each form of hydrogen storage corresponds to its own application area of hydrogen energy.
[0003] Solid-state hydrogen storage technology is based on the hydrogen absorption and desorption characteristics of certain substances and the heat exchange phenomenon that accompanies the hydrogen absorption and desorption process. It leverages the advantages of high safety and high volume density to develop applications in hydrogen energy scenarios.
[0004] Existing solid-state hydrogen storage power supply systems suffer from insufficient heat from the solid-state hydrogen storage cylinders, affecting hydrogen release, or require additional electricity to electrically heat the solid-state hydrogen storage cylinders, resulting in low system efficiency.
[0005] In addition, existing solid-state hydrogen storage power supply systems have low integration, generally only integrating fuel cell stacks, controllers, and solid-state hydrogen storage cylinders. This results in problems such as inconvenience of use, insufficient compactness of structure, unreasonable layout, insufficient capacity to accommodate hydrogen storage cylinders, and poor utilization of fuel cell stack waste heat.
[0006] It is evident that existing hydrogen power generation systems suffer from numerous technical problems, including insufficient and uneven heat supply from solid hydrogen storage cylinders, poor heat retention, low internal structural integration, insufficient compactness, incomplete functionality, inadequate capacity to accommodate a large number of hydrogen storage cylinders, and low waste heat utilization. Utility Model Content

[0008] To achieve the above objectives, this application provides the following technical solutions.
[0009] According to a first aspect of this application, the baffle assembly is used in a flow guiding module of a hydrogen power generation system. The flow guiding module includes a first housing having a first space. The first housing has a first opening and a second opening spaced apart. The baffle assembly includes: a baffle, at least a portion of which is located in the first space and disposed at the first opening; a gap between the baffle and an inner wall surface of the first housing opposite to the first opening; a first flow guiding channel formed between the second opening and a portion of the first opening; and a second flow guiding channel formed between the second opening, the gap, and another portion of the first opening; and a first driving member connected to the baffle for driving the baffle to move within the first space.
[0010] Optionally, the baffle assembly further includes: a fixing seat, in which the baffle is installed and connected to the first driving member, the fixing seat being mounted on the bracket of the hydrogen power generation system.
[0011] Optionally, the mounting base includes: a first mounting part, which is mounted on the bracket of the hydrogen power generation system; a rotating part, which is rotatably disposed on the first mounting part and connected to the first driving member; and a second mounting part, which is connected to the rotating part and moves synchronously with the rotating part, the second mounting part having a mounting cavity, and one end of the baffle is mounted in the mounting cavity.
[0012] Optionally, the fixing base is provided with a mounting hole, and the baffle includes: a connecting part, at least a portion of which is located inside the fixing base, and the connecting part is limited by the edge of the mounting hole; and a body, one end of which is connected to the connecting part, and the other end of which extends out of the mounting hole.
[0013] Optionally, the connecting part is located inside the fixed base, and the main body and the connecting part are coaxially arranged.
[0014] Optionally, one end of the connecting part extends into the fixing seat, and the other end of the connecting part extends out of the fixing seat and is connected to the body. There is an angle between the extension direction of the body and the connecting part, and the body is located outside the fixing seat.
[0015] Optionally, there may be multiple baffles that are spaced apart, and the multiple baffles may be connected to one of the first driving components, or the multiple baffles may be connected to multiple first driving components in a one-to-one correspondence.
[0016] Optionally, the first driving element includes a linear motor or a rotary motor.
[0017] The flow guiding module for a hydrogen power generation system according to this application includes: a first housing having a first space, and the first housing having a first opening and a second opening spaced apart; a baffle assembly according to any of the above, wherein at least a portion of the baffle of the baffle assembly is located in the first space and disposed at the first opening, a gap is formed between the inner wall surface of the first housing opposite to the first opening and the baffle, a first flow guiding channel is formed between the second opening and a portion of the first opening, and a second flow guiding channel is formed between the second opening, the gap and another portion of the first opening.
[0018] The hydrogen power generation system according to this application includes: a hydrogen storage module, the hydrogen storage module including a second housing and a hydrogen storage component disposed within the second housing, the hydrogen storage component including a hydrogen storage cylinder, the interior of the second housing communicating with a first opening, and the second housing having an air outlet; a fuel cell module, the fuel cell module including a third housing and a fuel cell stack disposed within the third housing; a flow guiding module, the flow guiding module being the flow guiding module described above; and a second driving member, the second driving member capable of introducing the heat generated by the fuel cell stack during operation into the second housing through the gap.
[0019] According to the baffle assembly of this application, a baffle and a first driving member are combined. The position of the baffle in the first space can be controlled by the first driving member. For example, the distance of the gap corresponding to the baffle can be controlled by the first driving member, or the tilt angle of the baffle can be controlled by the first driving member. By using a position-adjustable baffle, multiple fluid distribution methods can be realized to meet various working conditions. By using the first driving member in conjunction with the baffle, the degree of automation can be improved.
[0020] The flow guiding module for a hydrogen power generation system in this application includes the aforementioned baffle assembly. Because the baffles of the baffle assembly can be adjusted in position or tilt angle under the action of the first driving component, it not only allows for automated control but also enables multiple fluid distribution methods in the first and second flow guiding channels. This not only achieves dynamic response and precise matching of heating requirements, improving efficiency, but also allows for flexible adjustment in different time periods, dynamically adjusting the fluid ratio in the first and second flow guiding channels. Furthermore, it can accommodate a greater number, size, and shape of hydrogen storage cylinders. In addition, it can provide on-demand heating to different areas of the hydrogen storage cylinders, reducing energy waste.
[0021] The hydrogen power generation system of this application employs a hydrogen storage module, a fuel cell module, a flow guiding module, and a second drive component in tandem. On one hand, it can heat the hydrogen storage tank and, when the hydrogen storage tank is tilted, provide different amounts of heat to different parts of the tank based on the amount of hydrogen storage alloy powder accumulated in different parts of the tilted tank, thus providing precise heating and ensuring sufficient heat supply to the hydrogen storage tank, improving the working efficiency of the hydrogen storage module. Moreover, when the hydrogen storage tank is tilted, the hydrogen storage module can accommodate more hydrogen storage tanks. On the other hand, it can effectively utilize the heat dissipated by the fuel cell module during operation, improving waste heat utilization. Furthermore, by integrating the hydrogen storage module, fuel cell module, and flow guiding module, it has advantages such as improved heat retention, high integration, and compact structure.

[0068] In all the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.
[0069] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.
[0070] The baffle assembly according to embodiments of this application is described in detail below with reference to the accompanying drawings.
[0071] like Figures 1 to 18 As shown, according to an embodiment of this application, the baffle assembly is used in the flow guiding module 1 of the hydrogen power generation system 1000. The flow guiding module 1 includes a first housing 11, the first housing 11 has a first space 111, and the first housing 11 is provided with a first opening 112 and a second opening 113 that are spaced apart. The baffle assembly includes a baffle 121 and a first driving member.
[0072] Specifically, at least a portion of the baffle 121 is located in the first space 111 and is disposed in the first opening 112. The inner wall surface of the first housing 11, which is disposed opposite to the first opening 112, has a gap 122 between it and the baffle 121. A first flow channel 123 is formed between the second opening 113 and a portion of the first opening 112. A second flow channel 124 is formed between the second opening 113, the gap 122, and another portion of the first opening 112. A first driving member is connected to the baffle 121 to drive the baffle 121 to move within the first space 111.
[0073] In other words, the baffle assembly according to the embodiments of this application is used in the flow guiding module 1 of a hydrogen power generation system 1000. For example, the hydrogen power generation system 1000 includes a flow guiding module 1, a hydrogen storage module 2, and a fuel cell module 3. The flow guiding module 1 includes a first housing 11, the first housing 11 having a first space 111, and a first opening 112 and a second opening 113 spaced apart. The first opening 112 can communicate with the interior of the hydrogen storage module 2. For example, the hydrogen storage module 2 includes a second housing 21, and the first opening 112 communicates with the second space 211 of the second housing 21. The second opening 113 can communicate with the interior of the fuel cell module 3. For example, the fuel cell module 3 includes a third housing 31, and the second opening 113 communicates with the third space 311 of the third housing 31. Heat inside the fuel cell module 3 can enter the first space 111 through the second opening 113, and then enter the third space 311 through the second opening 113.
[0074] Furthermore, at least a portion of the baffle 121 is installed in the first space 111; for example, the entire baffle 121 is located within the first space 111; or, the upper end of the baffle 121 is located in the first space 111, and the lower end extends out of the first opening 112 from the first space 111. A gap 122 exists between the inner wall surface of the first housing 11, which is opposite to the first opening 112, and the baffle 121. For example, one end of the baffle 121 extends towards the top plate 114 and has a gap 122 with the inner wall of the top plate 114, while the other end of the baffle 121 extends towards the first opening 112. When the baffle 121 extends in the vertical direction, a gap 122 exists between the inner wall surface of the top plate 114 and the upper end of the baffle 121.
[0075] A first flow channel 123 is formed between the second opening 113 and a portion of the first opening 112, and a second flow channel 124 is formed between the second opening 113, the gap 122, and another portion of the first opening 112. That is, the inner wall region on the first housing 11 opposite to the second opening 113 and the second opening 113 can be spaced apart from the baffle 121. For example, according to the approximate flow direction of the fluid flowing out of the second opening 113, the area roughly in the same direction as the fluid flow is defined as the front, and the area roughly opposite to the fluid flow is defined as the rear. The rear of the baffle 121 is spaced apart from the second opening 113, and the front of the baffle 121 is spaced apart from the inner wall of the first housing 11. A portion of the fluid flowing out from the second opening 113 is located between the inner wall of the baffle 121 and the side plate 115 behind the baffle 121, and flows into the hydrogen storage module 2 along the first guide channel 123; another portion of the fluid flowing out from the second opening 113 passes through the gap 122 and flows towards the inner wall of the side plate 115 in front of the baffle 121, and flows into the hydrogen storage module 2 along the second guide channel 124.
[0076] Furthermore, the first driving member is connected to the baffle 121, allowing the baffle 121 to move within the first space 111. This means that the relative position between the baffle 121 and the second opening 113 can be flexibly controlled using the first driving member, making it adaptable to various sizes of hydrogen storage cylinders 221 and highly automated. Optionally, the position of the baffle 121 is adjustable to adjust the size of the gap 122. For example, the height of the baffle 121 in the vertical direction is adjustable; or, for example, the position of the baffle 121 in the horizontal direction is adjustable. Optionally, the angle of inclination of the extending direction of the baffle 121 relative to the axis of the first opening 112 is adjustable.
[0077] According to one embodiment of this application, such as Figures 13 to 17 As shown, the relative positional relationship between the baffle 121 and the second opening 113 is adjustable. Optionally, the position of the baffle 121 is adjustable in the first direction to adjust the size of the gap 122. For example, the height of the baffle 121 in the first direction is adjustable. Optionally, the position of the baffle 121 is adjustable in the second direction. In this embodiment, by employing a positionally adjustable baffle 121, multiple fluid distribution schemes in the first flow channel 123 and the second flow channel 124 can be realized to meet various operating conditions.
[0078] Therefore, the baffle assembly according to the embodiments of this application adopts a combination of baffle 121 and a first driving member. The position of baffle 121 in the first space 111 can be controlled by the first driving member. For example, the distance of the gap 122 corresponding to baffle 121 can be controlled by the first driving member, or the tilt angle of baffle 121 can be controlled by the first driving member. By adopting a position-adjustable baffle 121, multiple fluid distribution methods can be realized to meet multiple working conditions. By adopting the first driving member in cooperation with baffle 121, the degree of automation can be improved.
[0079] According to one embodiment of this application, such as Figures 13 to 18 As shown, the baffle assembly further includes a fixing seat 125, in which a baffle 121 is installed and connected to the first driving member. The fixing seat 125 is mounted on the bracket 222 of the hydrogen power generation system 1000. For example, the fixing seat 125 is installed at the upper end of the bracket 222, the fixing seat 125 has a mounting cavity, the lower end of the baffle 121 is installed in the mounting cavity, and the upper end of the baffle 121 extends out of the mounting cavity. The fixing seat 125 can serve as a carrier for installing the baffle 121. The fixing seat 125 is connected to the first driving member, which can drive the fixing seat 125 and the baffle 121 installed in the fixing seat 125 to move together, for example, driving the baffle 121 to move in the vertical direction or rotate. In this embodiment, the installation process of the baffle 121 can be simplified by using the fixing seat 125.
[0080] In some specific embodiments of this application, such as Figure 18 As shown, the fixed base 125 includes: a first mounting part 1251, a rotating part 1252, and a second mounting part 1253.
[0081] Specifically, the first mounting part 1251 is mounted on the bracket 222 of the hydrogen power generation system 1000, the rotating part 1252 is rotatably disposed on the first mounting part 1251 and connected to the first driving member, the second mounting part 1253 is connected to the rotating part 1252 and moves synchronously with the rotating part 1252, the second mounting part 1253 has a mounting cavity, one end of the baffle 121 is mounted in the mounting cavity, which can improve the installation reliability of the baffle 121.
[0082] For example, the bracket 222 includes a fixing plate 2221, a first mounting part 1251 connected to the upper end of the fixing plate 2221, a rotating part 1252 provided on the first mounting part 1251, and a second mounting part 1253 provided on the rotating part 1252. The second mounting part 1253 can rotate together with the rotating part 1252, thereby controlling the baffle 121 to rotate together. Optionally, the first driving member can be disposed inside the mounting cavity.
[0083] In this embodiment, by combining the first mounting part 1251, the rotating part 1252, and the second mounting part 1253, it is not only convenient to install the baffle 121, but also convenient to rotate the baffle 121 to adjust the tilt angle of the baffle 121.
[0084] According to one embodiment of this application, the fixing seat 125 is provided with a mounting hole, and the baffle 121 includes a connecting part 1211 and a body 1212. At least a portion of the connecting part 1211 is located inside the fixing seat 125, that is, at least a portion of the connecting part 1211 is located inside the mounting cavity. The connecting part 1211 is limited by the edge of the mounting hole, that is, the width of at least a portion of the connecting part 1211 is greater than the radial dimension of the mounting hole, which can limit the range of motion of the baffle 121.
[0085] One end of the main body 1212 is connected to the connecting part 1211, and the other end of the main body 1212 extends out of the mounting hole and is located outside the mounting cavity. For example, the main body 1212 is provided at the upper end of the connecting part 1211, and the lower end of the connecting part 1211 is provided in the mounting cavity, which facilitates the installation between the baffle 121 and the fixing seat 125.
[0086] In this embodiment, by combining the connecting part 1211 and the body 1212, it is not only convenient to install the baffle 121, but also to prevent the baffle 121 from detaching from the fixing seat 125.
[0087] In some specific embodiments of this application, such as Figure 18As shown, the connecting portion 1211 is located within the fixing base 125, and the body 1212 is coaxially arranged with the connecting portion 1211. For example, a mounting hole is provided at the upper end of the second mounting portion 1253 along its axial direction and communicates with the mounting cavity. The lower end of the body 1212 extends into the second mounting portion 1253 and connects with the connecting portion 1211, while the upper end of the body 1212 extends out of the second mounting portion 1253. In this embodiment, by adopting a coaxial arrangement between the body 1212 and the connecting portion 1211, the space occupied by the baffle 121 can be reduced.
[0088] According to one embodiment of this application, such as Figure 16 As shown, one end of the connecting part 1211 extends into the fixed base 125, and the other end of the connecting part 1211 extends out of the fixed base 125 and is connected to the body 1212. There is an angle between the extension direction of the body 1212 and the connecting part 1211. For example, the body 1212 and the connecting part 1211 are perpendicular to each other. The body 1212 is located outside the fixed base 125, which can expand the size and range of motion of the baffle 121.
[0089] As can be seen, the baffle 121 has various shapes to meet different needs.
[0090] According to one embodiment of this application, such as Figure 18 As shown, there are multiple baffles 121, which are spaced apart, for example, spaced apart along a second direction. Multiple baffles 121 are connected to a first driving member, or multiple baffles 121 are connected to multiple first driving members in a one-to-one correspondence. In this embodiment, by using multiple baffles 121 and first driving members in cooperation, further distribution and fine control of the flow direction of the fluid flowing out from the second opening 113 can be achieved, and it can be applied to more different working conditions.
[0091] In some specific embodiments of this application, the first driving component includes a linear motor. For example, the flow guiding module 1 and the hydrogen storage module 2 are arranged in a first direction, and the flow guiding module 1 and the fuel cell module 3 are arranged in a second direction. The position of the linear motor-driven baffle 121 is adjustable in the first and / or second directions. In this embodiment, the linear motor-driven baffle 121 can perform linear motion.
[0092] The combination of the baffle 121 and the linear motor of this application will be described in detail below with reference to several embodiments.
[0093] Example 1
[0094] like Figure 13As shown, the main body 1212 extends generally along a first direction, and the connecting portion 1211 extends generally along a second direction. One end of the connecting portion 1211 extends into the fixed base 125, and the other end is connected to the main body 1212. In the second direction, the main body 1212 is located outside the fixed base 125. A linear motor is located inside the fixed base 125 and connected to one end of the connecting portion 1211. The linear motor can drive the main body 1212 to move in the first direction, for example, along the vertical direction, to realize the lifting and lowering of the baffle 121.
[0095] Example 2
[0096] like Figure 14 As shown, in the first direction, the main body 1212 is located above the connecting part 1211, and the connecting part 1211 extends entirely into the fixed base 125. In the first direction, the upper end and middle part of the main body 1212 are located above the fixed base 125, and the lower end of the main body 1212 is connected to the connecting part 1211. The main body 1212 and the connecting part 1211 extend along the first direction respectively. The linear motor is connected to the connecting part 1211 and drives the main body 1212 to move in the first direction, for example, along the vertical direction, so as to realize the lifting and lowering of the baffle 121.
[0097] Example 3
[0098] like Figure 15 As shown, the mounting base 125 includes a first mounting part 1251, a rotating part 1252, and a second mounting part 1253. The lower end of the first mounting part 1251 is mounted on the mounting plate 2221, the rotating part 1252 is mounted on the upper end of the first mounting part 1251, and the second mounting part 1253 extends along a first direction and is mounted on the rotating part 1252.
[0099] The main body 1212 extends generally along a first direction, and the connecting portion 1211 extends generally along a second direction. One end of the connecting portion 1211 extends into the mounting cavity of the second mounting portion 1253, and the other end is connected to the main body 1212. In the second direction, the main body 1212 is located outside the fixing base 125.
[0100] The linear motor is located inside the mounting cavity and connected to one end of the connecting part 1211. The linear motor can drive the body 1212 to move in the first direction, thereby realizing the lifting and lowering of the baffle 121.
[0101] According to one embodiment of this application, the first driving member includes a rotary motor that drives the baffle 121 to rotate. In this embodiment, the rotary motor drives the baffle 121 to rotate, for example, to rotate around the rotating part 1252.
[0102] The combination of the baffle 121 and the rotary motor of this application will be described in detail below with reference to several embodiments.
[0103] Example 4
[0104] like Figure 16 As shown, the mounting base 125 includes a first mounting part 1251, a rotating part 1252, and a second mounting part 1253. The lower end of the first mounting part 1251 is mounted on the mounting plate 2221, the rotating part 1252 is mounted on the upper end of the first mounting part 1251, and the second mounting part 1253 extends along a first direction and is mounted on the rotating part 1252.
[0105] The main body 1212 extends generally along a first direction, and the connecting part 1211 extends generally along a second direction. One end of the connecting part 1211 extends into the mounting cavity of the second mounting part 1253, and the other end is connected to the main body 1212. In the second direction, the main body 1212 is located outside the second mounting part 1253.
[0106] The rotary motor is connected to the rotating part 1252, which drives the second mounting part 1253 to rotate. The connecting part 1211 extends into the mounting cavity of the second mounting part 1253, thereby enabling the rotary motor to drive the main body 1212 to rotate and adjust the windward angle of the baffle 121.
[0107] Example 5
[0108] like Figure 17 As shown, the mounting base 125 includes a first mounting part 1251, a rotating part 1252, and a second mounting part 1253. The lower end of the first mounting part 1251 is mounted on the mounting plate 2221, the rotating part 1252 is mounted on the upper end of the first mounting part 1251, and the second mounting part 1253 extends along a first direction and is mounted on the rotating part 1252.
[0109] In the first direction, the main body 1212 can be located above the connecting part 1211. The rotary motor drives the rotating part 1252 to rotate, and the connecting part 1211 is installed on the second mounting part 1253, thereby realizing the rotary motor driving the main body 1212 to rotate, and realizing the adjustment of the windward angle of the baffle 121.
[0110] This application also discloses a flow guiding module 1 for a hydrogen power generation system 1000, including: a first housing 11 and a baffle assembly.
[0111] Specifically, the first housing 11 has a first space 111, and the first housing 11 is provided with a first opening 112 and a second opening 113 that are spaced apart. At least a portion of the baffle 121 of the baffle assembly is located in the first space 111 and is provided in the first opening 112. There is a gap 122 between the inner wall surface of the first housing 11 that is opposite to the first opening 112 and the baffle 121. A first flow channel 123 is formed between the second opening 113 and a portion of the first opening 112, and a second flow channel 124 is formed between the second opening 113, the gap 122 and another portion of the first opening 112.
[0112] In other words, the flow guiding module 1 for a hydrogen power generation system 1000 according to the embodiments of this application mainly includes: a first housing 11 and a baffle 121. A first space 111 is defined in the first housing 11. A first opening 112 and a second opening 113 are provided on the first housing 11. For example, the first housing 11 includes a top plate 114 and a side plate 115 disposed on the outer periphery of the top plate 114. The top plate 114 and the side plate 115 enclose the first space 111 with the first opening 112. The side plate 115 is provided with the second opening 113.
[0113] In this embodiment, the first space 111 can be divided into multiple channels by the cooperation of the baffle 121 and the first housing 11. For example, a first guide channel 123 is formed between the second opening 113 and a portion of the first opening 112, and a second guide channel 124 is formed between the second opening 113, the gap 122, and another portion of the first opening 112. Gas enters the first space 111 through the second opening 113, changes its flow direction under the action of the baffle 121, and flows out of the first opening 112 along the first guide channel 123 and the second guide channel 124 respectively.
[0114] The flow guiding module 1 of this application embodiment can be applied to a hydrogen power generation system 1000. The hydrogen power generation system 1000 also includes a hydrogen storage module 2 and a fuel cell module 3. The fuel cell module 3 can correspond to the second opening 113, and the hydrogen storage module 2 can correspond to the first opening 112. The waste heat from the fuel cell module 3 can not only heat a portion of the hydrogen storage module 2 with the gas flowing out along the first flow guiding channel 123, but also heat another portion of the hydrogen storage module 2 with the gas flowing out along the second flow guiding channel 124. In use, the flow direction of the fluid can be changed by the cooperation of the baffle 121 and the first housing 11, thereby achieving heating of the preset position of the hydrogen storage component 22 in the hydrogen storage module 2.
[0115] Optionally, the hydrogen storage module 2 and the fuel cell module 3 are distributed along a first direction, and the flow guiding module 1 and the fuel cell module 3 are distributed along a second direction. There is an angle between the first direction and the second direction, for example, the first direction is perpendicular to the second direction. This is conducive to the compact arrangement of the flow guiding module 1, the hydrogen storage module 2 and the fuel cell module 3, and saves space.
[0116] Optionally, the first opening 112 and the top plate 114 are disposed opposite to each other in the first direction, and the baffle 121 can extend approximately along the first direction. One end of the baffle 121 in the first direction is spaced apart from the inner wall of the top plate 114, which facilitates the setting of the baffle 121 and also helps to prolong the residence time of the gas in the first housing 11.
[0117] Optionally, at least a portion of the baffle 121 is disposed opposite to the second opening 113 in the second direction, so as to influence the direction of the gas flowing out of the second opening 113 through the baffle 121.
[0118] Optionally, the fluid flowing out of the second opening 113 can be in a direction that is approximately parallel to the second direction when it is not disturbed by the baffle 121, so as to facilitate the flow to the position of the baffle 121.
[0119] According to one embodiment of this application, such as Figure 6 As shown, there are multiple baffles 121, which are spaced apart. Optionally, the multiple baffles 121 are spaced apart along a second direction. For example, there are two baffles 121, namely a first baffle and a second baffle. A first gap 1221 is formed between the upper end of the first baffle and the top plate 114, and a second gap 1222 is formed between the upper end of the second baffle and the top plate 114. A portion of the fluid flowing out from the second opening 113 flows to the first baffle, another portion of the fluid flows to the second baffle after passing through the first gap 1221, and yet another portion of the fluid flows to the area on the inner wall of the first housing 11 opposite to the second opening 113 after passing through the first gap 1221 and the second gap 1222. The rear side of the first baffle is spaced apart from the second opening 113 and forms a first flow channel 123. The first baffle and the second baffle are spaced apart in the front-rear direction, and a second flow channel 124 is formed between the first baffle and the second baffle. The front side of the second baffle is spaced apart from the inner wall of the first housing 11, and forms another second flow channel 124.
[0120] In some specific embodiments of this application, such as Figure 6 As shown, the gap 122 corresponding to the baffle 121 closer to the second opening 113 is larger than the gap 122 corresponding to the baffle 121 farther from the second opening 113. For example, there are two baffles 121, namely a first baffle and a second baffle, with the first baffle located on the side of the second baffle closer to the second opening 113. A first gap 1221 is formed between the upper end of the first baffle and the top plate 114, and a second gap 1222 is formed between the upper end of the second baffle and the top plate 114. The gap 122 between the first baffle and the top plate 114 can be defined as S1, and the gap 122 between the second baffle and the top plate 114 can be defined as S2, where S1 is greater than S2.
[0121] In this embodiment, by controlling the size of the gap 122 corresponding to different baffles 121, the amount of gas in the first guide channel 123 and the second guide channel 124 can be distributed and controlled.
[0122] This application also discloses a hydrogen power generation system 1000, including: a hydrogen storage module 2, a fuel cell module 3, a flow guiding module 1, and a second drive component 4.
[0123] Specifically, the hydrogen storage module 2 includes a second housing 21 and a hydrogen storage component 22 disposed within the second housing 21. The hydrogen storage component 22 includes a hydrogen storage bottle 221. The interior of the second housing 21 is connected to the first opening 112. The second housing 21 has an air outlet 212. The fuel cell module 3 includes a third housing 31 and a fuel cell stack 32 disposed within the third housing 31. The flow guiding module 1 is the flow guiding module 1 according to any of the above embodiments. The second driving member 4 can introduce the heat generated when the fuel cell stack 32 is working into the second housing 21 through the gap 122.
[0124] In other words, the outer shell of the hydrogen power generation system 1000 may include a first shell 11, a second shell 21, and a third shell 31, which can be manufactured by integral molding, fixed connection, or detachable assembly, offering high flexibility. The outer shell defines a receiving space, including a first space 111, a second space 211, and a third space 311, which are interconnected. Specifically, the first shell 11 has a first space 111, the second shell 21 has a second space 211, and the third shell 31 has a third space 311. A baffle 121 may be installed in the first space 111, a hydrogen storage component 22 may be installed in the second space 211, and a fuel cell assembly may be installed in the third space 311. The fuel cell assembly may include a fuel cell stack 32; for example, a mounting frame 33 may be provided in the third space 311, and the fuel cell stack 32 may be mounted on the mounting frame 33.
[0125] The first housing 11 has a first opening 112 and a second opening 113, and the second housing 21 has an air outlet 212. The second opening 113 can be opposite to the second driving member 4, for example, the second driving member 4 is located at the second opening 113. The second opening 113 is connected to the first space 111 and the third space 311 respectively. The second driving member 4 can drive the heat of the fuel cell assembly in the third space 311 to be introduced into the first space 111 through the second opening 113, and then flow out of the first opening 112 through the guide channel and into the second space 211. For example, a fan for heat dissipation of the fuel cell stack 32 inside the fuel cell module 3 is provided at the rear. This fan can both draw in external air into the airflow channel of the fuel cell stack 32 to supply oxygen for the reduction reaction, and conduct the hot air generated by the fuel cell stack 32 during operation to the hydrogen storage module 2, thereby improving the hydrogen release efficiency of the hydrogen storage module 2. The second driving member 4 includes, but is not limited to, a fan.
[0126] Optionally, the second space 211 and the first space 111 are arranged along the first direction, and the third space 311 and the first space 111 are arranged along the second direction, for example, the first direction is the up-down direction and the second direction is the front-back direction. The first direction and the second direction are perpendicular to each other, which helps to improve the appearance and structural compactness of the shell.
[0127] In some specific embodiments of this application, such as Figure 7 As shown, the hydrogen storage assembly 22 further includes a bracket 222, which is installed inside the second housing 21. The bracket 222 is used to install the hydrogen storage assembly 22, for example, the hydrogen storage assembly 22 includes a hydrogen storage cylinder 221, and the bracket 222 is used to install the hydrogen storage cylinder 221. In this embodiment, the use of the bracket 222 facilitates the support and fixation of the hydrogen storage assembly 22.
[0128] Optionally, the bracket 222 is provided with a mounting through hole 2222 for mounting the hydrogen storage cylinder 221 of the hydrogen storage assembly 22. That is, the hydrogen storage assembly 22 includes a hydrogen storage cylinder 221, which can be installed in the mounting through hole 2222. The fluid flowing out from the guide channel can correspond to a preset position on the hydrogen storage cylinder 221, thereby heating the preset position of the hydrogen storage cylinder 221.
[0129] Optionally, the axis of the mounting through hole 2222 is inclined relative to the second direction, which can realize that multiple hydrogen storage cylinders 221 are fixedly and inclinedly installed in the second space 211.
[0130] Optionally, multiple through holes 2222 can be installed to install more hydrogen storage cylinders 221, thereby improving the energy storage effect and allowing multiple hydrogen storage cylinders 221 to be heated simultaneously.
[0131] Optionally, there may be multiple mounting through holes 2222, which are divided into multiple rows of mounting through holes 2222 in the first direction. For example, the multiple mounting through holes 2222 may be divided into multiple rows of mounting through holes 2222 along the first direction, and each row of mounting through holes 2222 may include multiple mounting through holes 2222 spaced apart along the second direction.
[0132] According to one embodiment of this application, such as Figure 3 As shown, the bracket 222 includes multiple fixing plates 2221, which are spaced apart. Each fixing plate 2221 has a mounting through hole 2222, and the mounting through holes 2222 on the multiple fixing plates 2221 have a height difference to install and control the tilt angle of the hydrogen storage cylinder 221. This can prolong the residence time of the fluid flowing out from the second opening 113 in the second space 211. The hot air can remain in the second space 211 for a longer time before being discharged, resulting in better heat retention. For example, the bracket 222 includes two fixing plates 2221, which are spaced apart in a second direction. Each fixing plate 2221 has a mounting through hole 2222, and the mounting through holes 2222 on the two fixing plates 2221 have a height difference in a first direction. The end of the fixing plate 2221 away from the baffle 121 in the first direction has an exhaust port 2223.
[0133] When the second direction is the front-to-back direction, the two fixing plates 2221 can be distributed front-to-back, and each fixing plate 2221 has a mounting through hole 2222 that is slightly larger than the diameter of the hydrogen storage cylinder 2212. The front and rear fixing plates 2221 can cooperate to fix the same hydrogen storage cylinder 221. The heights of the mounting through holes 2222 on the front fixing plate 2221 and the rear fixing plate 2221 can be different, so that the hydrogen storage cylinder 221 is placed at a stable tilt angle in the second space 211.
[0134] Among them, the hydrogen storage module 2 adopts a horizontal hydrogen storage bottle 221 design, which can accommodate more hydrogen storage bottles 221, and the sloping design also makes it more convenient to replace the hydrogen storage bottle 221.
[0135] Furthermore, the two fixed plates 2221 spaced apart along the second direction can divide the second space 211 into a head space 261, a middle space 262 and a tail space 263 distributed sequentially along the second direction. When the hydrogen storage bottle 221 is placed at an angle, the head space 261 corresponds to the head of the hydrogen storage bottle 221, the middle space 262 corresponds to the body 2212 of the hydrogen storage bottle 221, and the tail space 263 corresponds to the tail 2213 of the hydrogen storage bottle 221.
[0136] As can be seen, the two fixed plates 2221, in conjunction with the baffle 121, allow hot air to pass through the head 2211, body 2212, and tail 2213 of the hydrogen storage cylinder 221, resulting in more uniform heating of the different areas of the hydrogen storage cylinder 221 and better heating effect. For example, based on the amount of hydrogen storage alloy powder accumulated in different parts of the inclined hydrogen storage cylinder 221, different amounts of heat can be provided to different parts of the hydrogen storage cylinder 221, enabling precise heating and ensuring better utilization of waste heat.
[0137] Understandably, if the baffle 121 is not installed, the hot air vented by the fan can easily flow directly to the tail space 263, causing the tail 2213 of the bottle to be heated more, but the body 2212 of the bottle is not heated evenly.
[0138] In contrast, in this embodiment of the application, by using a baffle 121, a portion of the heat can be intercepted to heat the bottle body 2212 and the bottle head 2211 separately, which makes the heating of the bottle body 2212 more uniform.
[0139] Optionally, the baffle 121 is mounted on the bracket 222, for example, directly or indirectly mounted on the upper end of the fixed plate 2221, so as to make full use of the bracket 222.
[0140] According to one embodiment of this application, such as Figure 5As shown, the baffle 121 of the flow guiding module 1 is installed on the fixed plate 2221. The baffle 121 and the fixed plate 2221 correspond one-to-one. For example, there are two baffles 121 and two fixed plates 2221, and they correspond one-to-one. Hot gas flowing out from one first flow guiding channel 123 enters the head space 261, hot gas flowing out from one second flow guiding channel 124 enters the middle space 262, and hot gas flowing out from another second flow guiding channel 124 enters the tail space 263. This not only facilitates the installation of the baffle 121, but also allows the space in the second space 211 separated by the fixed plate 2221 to correspond one-to-one with the space in the first space 111 separated by the baffle 121, which is beneficial for heating different parts of the hydrogen storage cylinder 221 in the second space 211.
[0141] In some specific embodiments of this application, the hydrogen storage cylinder 221 includes a head 2211, a body 2212, and a tail 2213. The head 2211 corresponds to the first flow channel 123, and the height of the head 2211 is higher than that of the body 2212 and the tail 2213. Furthermore, when the hydrogen storage cylinder 221 is tilted, in the second direction, the head 2211 of the hydrogen storage cylinder 221 can be closer to the second opening 113 relative to the tail 2213. In this embodiment, the hydrogen storage cylinder 221 is tilted relative to the second direction. In both the second and first directions, the head 2211 of the hydrogen storage cylinder 221 is closer to the second opening 113 relative to the tail 2213, meaning the height of the head 2211 of the hydrogen storage cylinder 221 is higher than the height of the tail 2213.
[0142] It is understandable that when the hydrogen storage bottle 221 is tilted and contains hydrogen storage alloy powder, in the first direction, the bottle head 2211 is higher than the bottle tail 2213. Due to the tilt of the hydrogen storage bottle 221 and the influence of gravity, there is more metal powder at the bottom of the bottle than at the body 2212 and the bottle head 2211. Therefore, it is necessary to heat it more to ensure the hydrogen release rate when releasing hydrogen.
[0143] In addition, such as Figure 6 As shown, by limiting the first gap 1221 to be greater than the second gap 1222, a small amount of hot air can enter the head space 261 corresponding to the bottle head 2211, a slightly larger amount of hot air can enter the middle space 262 of the bottle body 2212, and a larger amount of hot air can enter the tail space 263 of the bottle tail 2213.
[0144] According to one embodiment of this application, such as Figure 6 As shown, in the second direction, the distance between the second opening 113 and the first baffle is defined as S3, the distance between the first baffle and the second baffle is defined as S4, and the distance between the second baffle and the inner wall of the first housing 11 is defined as S5.
[0145] Optionally, S3=S4=S5, that is, the distribution can be even in the second direction, which makes it easier to set up the baffle 121 and the hydrogen storage bottle 221 to be heated evenly.
[0146] Optionally, S5 is greater than S4 and S3, which can improve the heating effect on the bottle tail 2213.
[0147] According to one embodiment of this application, such as Figure 3 As shown, an exhaust vent 2223 is provided at one end of the fixed plate 2221 near the air outlet 212. The exhaust vent 2223 facilitates the passage of air. The hot air entering the head space 261 and the middle space 262 will eventually pass through the exhaust vent 2223 to reach the tail space 263, which can be connected to the air outlet 212 and discharged to the outside.
[0148] Optionally, the third housing 31 and the first housing 11 can be arranged adjacent to each other and share a portion of the structure. For example, the side plate 115 includes a partition 1151, and the partition 1151 can be provided with a second opening 113, which communicates with both the third space 311 and the first space 111. The partition 1151 can be part of both the third housing 31 and the first housing 11. That is, the partition 1151 can be used to separate the third housing 31 and the first housing 11 in a second direction. For example, one side of the partition 1151 is the first space 111, and the other side is the third space 311. The baffle 121 is located on one side of the partition 1151, and the fuel cell assembly is located on the other side of the partition 1151.
[0149] Optionally, the second housing 21 includes a box and a cover 25, which can cooperate to form a second space 211. Optionally, the cover 25 and the box can be connected by a hinge 116. Optionally, the cover 25 can be opened to facilitate the installation and removal of the hydrogen storage cylinder 221. The box, the bracket 222 installed inside the box, and the hydrogen storage cylinder 221 installed on the bracket 222 can constitute a hydrogen storage module 2. The box may be provided with an air outlet 212. Optionally, the air outlet 212 includes multiple air holes arranged in a matrix.
[0150] Optionally, the third housing 31 includes a movable plate 315. The fuel cell assembly and the third housing 31, etc., can constitute the fuel cell module 3.
[0151] Optionally, the third housing 31 may include an upper plate 312, two intermediate plates 313, a bottom plate 314, and a partition 1151. The upper plate 312, intermediate plates 313, bottom plate 314, and partition 1151 cooperate to form a third space 311. The second opening 113 on the partition 1151 may include multiple ventilation holes forming a matrix, which can be used to release heat from inside the fuel cell assembly to the outside.
[0152] Optionally, a first connecting hole 3141 and a second connecting hole 3142 are provided on the base plate 314. The first connecting hole 3141 and the second connecting hole 3142 can be used to run pipes, wires, etc.
[0153] Alternatively, hydrogen can first pass through the intake solenoid valve 376 before being transmitted to the input end of the fuel cell assembly 5.
[0154] Optionally, three horizontal hydrogen storage cylinders 221 are used as a group, and the hydrogen supply pipelines of different hydrogen storage cylinders 221 are connected through a three-way valve 223. The pipelines are then connected to the hydrogen output control solenoid valve 225 next to each group. The hydrogen output control solenoid valve 225 of each group is connected to the main hydrogen supply pipeline 224 through a three-way valve arranged vertically.
[0155] Optionally, the upper end of the hydrogen main pipe 224 enters the fuel cell assembly through the first connecting hole 3141, passes through the pressure sensor 373, and is then connected to the intake solenoid valve 376 and the hydrogen inlet 321.
[0156] Optionally, the opening and closing of the intake solenoid valve 376 can be controlled by the control mainboard 375.
[0157] Optionally, the communication and power supply lines of the hydrogen output control solenoid valve 225 can enter the fuel cell assembly through the first connecting hole 3141 and the second connecting hole 3142, and are respectively connected to the control motherboard 375 and the battery, such as a lithium battery.
[0158] Alternatively, hydrogen can flow in approximately the following sequence: hydrogen main 224 - pressure sensor 373 - inlet solenoid valve 376 - hydrogen inlet 321 of fuel cell stack 32 - hydrogen outlet 322 of fuel cell stack 32 - outlet solenoid valve 374 - discharge through the second connecting hole 3142 of base plate 314.
[0159] The lithium battery can be used as a starting battery or to provide power when needed. The DC boost converter and lithium battery can switch between different output modes according to the actual situation and the equipment being used, demonstrating strong adaptability.
[0160] Optionally, the movable plate 315 has multiple matrix-arranged air inlets 3151 to facilitate the formation of airflow paths. For example, air enters the third space 311 from the air inlets 3151, and driven by the fan, the heat from the fuel cell stack 32 enters the first space 111 through the second opening 113, and enters the second space 211 under the action of the baffle 121.
[0161] Optionally, the movable panel 315 is equipped with a display screen 3152, which can display operational information, such as various types of information related to the fuel cell assembly and the hydrogen storage assembly 22. The movable panel 315 is equipped with a power button and a start button 3153, allowing the hydrogen power generation system 1000 to be shut down via the display screen 3152. The power button can be used to power on the fuel cell assembly and various devices within the housing space, while the start button 3153 can be used to power on and start the fuel cell assembly.
[0162] Optionally, the third housing 31 is also provided with a shutdown button 3154, which can be used to shut down the fuel cell assembly and disconnect power to the fuel cell assembly.
[0163] like Figures 9 to 11 As shown, the hidden movable panel 315 contains, from top to bottom and left to right, the fuel cell stack 32, DC boost converter, DC cooling device 35, DC buck converter 36, current sensor 371, relay 372, pressure sensor 373, and exhaust solenoid valve 374. Figures 9 to 11 As shown, the components arranged from the inside out are: mounting frame 33, DC step-down device 36, DC boost device, and DC heat dissipation device 35. The DC step-down device 36 can be installed on the partition 1151 of the fuel cell assembly. For example, there are two relays 372, one of which can be used to control the on / off state of the positive electrode, and the other can be used to control the on / off state of the negative electrode. A hydrogen output control solenoid valve 225 can be installed inside the second housing 21 to control the hydrogen output of a row of hydrogen storage cylinders 221.
[0164] Optionally, the mounting frame 33 can be fixed to the inner wall of the intermediate plate 313 on one side of the fuel cell assembly using screws. The DC boost converter and DC cooling device 35 can be mounted on the front of the mounting frame 33. The relay 372 can be mounted on the intermediate plate 313 on one side of the fuel cell assembly, and the pressure sensor 373 is mounted on the partition 1151 and located below the DC step-down device 36. The intake solenoid valve 376 and the exhaust solenoid valve 374 can be mounted on the partition 1151 and located below the fuel cell stack 32. The control mainboard 375 is mounted on the base plate 314 of the fuel cell assembly to reduce its volume and make the internal structure more compact.
[0165] Optionally, the fuel cell stack 32 is equipped with four stack fastening rods 34 for locking the multi-layer stack, which can help fix the position of the multi-stage electrode plates inside the fuel cell stack 32. Optionally, the fastening rods 34 are screws. Using four screws can achieve a fastening effect. After the multi-layer stack is stacked, it needs to be pressed with a hydraulic press. After pressing, it can be locked with screw nuts to maintain the internal pressure between the various components inside the fuel cell stack 32. The relay 372 next to the intake solenoid valve 376 can be used to control the on / off of the internal circuit.
[0166] like Figure 8 As shown, the second drive component 4 includes a fan. For example, a set of fans for stack airflow can be provided on the back of the fuel cell stack 32. On the one hand, it is used to draw outside air into the airflow channel of the fuel cell stack 32 to cause oxygen reduction reaction. On the other hand, it is used to conduct the hot air generated when the stack is working to the flow guiding module 1 at the rear. Since the hydrogen storage component 22 absorbs heat when releasing hydrogen, the temperature drop in the second space 211 will lead to a decrease in the hydrogen release efficiency of the hydrogen storage component 22. Therefore, conducting the hot air generated by the stack operation to the second space 211 through the flow guiding module 1 can improve the hydrogen release efficiency of the hydrogen storage component 22.
[0167] Optionally, the partition 1151 has a hollow design, and a third connecting hole 11511 is provided at the edge of the hollow. The third connecting hole 11511 can be used to pass wires through.
[0168] The fuel cell electric propulsion 32 can be connected to the hydrogen inlet 321 and the hydrogen outlet 322. Water and a very small amount of hydrogen output from the fuel cell stack 32 can be discharged through the hydrogen outlet 322 on the fuel cell electric propulsion 32.
[0169] The working process of the hydrogen power generation system 1000 of this application embodiment will be described in detail below with reference to specific embodiments.
[0170] After generating electricity, the fuel cell assembly first transmits it to a DC boost converter, which then transmits it to a lithium battery (not shown in the figure) and a DC buck converter 36. The lithium battery can serve as a starter battery, powering the fuel cell stack 32 when the user presses the power button. A current sensor 371 detects whether the current is normal. After passing through the current sensor 371, the current reaches the DC boost converter. If the lithium battery has sufficient charge, the current can be supplied to external devices without going to the lithium battery. Furthermore, the lithium battery can store electrical energy, which can be used to power external devices when needed. The lithium battery can also serve as a starter battery, powering all internal devices during startup.
[0171] Under specific circumstances, the DC boost converter and the lithium battery can simultaneously output current to the same external electrical device. In other words, the hydrogen power generation system 1000 of this application can switch between different output modes according to actual conditions and the different types of electrical devices it is adapted to (e.g., hydrogen-powered two-wheelers, vending machines, etc.), providing power to both hydrogen-powered two-wheelers and providing reliable and stable energy to vending machines, demonstrating strong adaptability. Optionally, the bottom of the front cover and the bottom of the housing of the second housing 21 of the hydrogen power generation system 1000 in this embodiment are equipped with fixing components, facilitating the screw fixing of the entire device to various electrical devices requiring energy, such as golf carts, vending machines, and other types of equipment, thus having a wide range of applications.
[0172] The DC step-down device 36 is electrically connected to the control motherboard 375 and other internal electrical devices. After voltage reduction by the DC step-down device 36, it can supply power to the fuel cell system control board and other internal electrical devices. Optionally, the control motherboard 375 is communicatively connected to the various devices included in the fuel cell assembly, and is used to control the operation of the fuel cell stack 32 in the fuel cell assembly, the opening and closing of the inlet solenoid valve 376 and the outlet solenoid valve 374, and other operations to achieve hydrogen delivery control.
[0173] Optionally, the fan for guiding the flow of the fuel cell stack 32 extends into the first space 111 inside the flow guiding module 1, which can effectively control the direction of airflow and improve space utilization.
[0174] Optionally, the baffle 121 can be fixed to the fixing plate 2221, for example, fixed to the upper end of the fixing plate 2221, for easy installation.
[0175] In addition, while the fuel cell stack 32 consumes hydrogen to generate electricity, the hydrogen output port 322 of the fuel cell will output a small amount of unconsumed hydrogen and water generated during power generation. Excess hydrogen and water generated will be output from the output end of the fuel cell stack 32, and under the control of the exhaust solenoid valve 374, will be directly output to the heat-conducting space through the connecting hole via a pipeline. The water will evaporate upon encountering the hot air in the heat-conducting space, and the excess hydrogen and the evaporated water vapor will be discharged to the outside through the exhaust port 2223 along with the hot air in the second space 211.
[0176] In summary, the hydrogen power generation system 1000 according to the embodiments of this application employs a hydrogen storage module 2, a fuel cell module 3, a flow guiding module 1, and a second driving component 4 in cooperation, which has advantages including but not limited to the following:
[0177] (1) For the flow guiding module 1, the flow guiding module 1 includes the above-mentioned baffle assembly. Since the baffle 121 of the above-mentioned baffle assembly can be adjusted in position or tilt angle under the action of the first driving component, it can not only be automatically controlled, but also realize multiple distribution methods of fluid in the first flow guiding channel 123 and the second flow guiding channel 124. It can not only realize the dynamic response of the hydrogen storage component 22, accurately match the heating requirements of the hydrogen storage bottle 221, and improve the heating efficiency; but also flexibly adjust and dynamically adjust the fluid ratio in the first flow guiding channel 123 and the second flow guiding channel 124 in different time periods; and can also adapt to more hydrogen storage bottles 221 of different numbers, sizes and shapes; in addition, it can also provide heat to different areas on the hydrogen storage bottle 221 as needed, reducing energy waste.
[0178] (2) For the hydrogen storage module 2, by adopting a reasonable arrangement of hydrogen storage cylinders 221 and a compact support structure, the number of hydrogen storage cylinders 221 that can be accommodated in a limited space is significantly increased; by the cooperation between the hydrogen storage module 2 and the flow guiding module 1, the residence time of heat in the hydrogen storage module 2 can be extended, and the heat can act stably on the hydrogen storage cylinders 221 for a long time, improving the heating effect and ensuring that the hydrogen storage cylinders 221 obtain sufficient and uniform heat. This not only improves the hydrogen release efficiency and ensures the stable power output of the hydrogen power generation system 1000, but also avoids the reduction of hydrogen release due to insufficient heat in some hydrogen storage cylinders 221, effectively improving the overall performance of the hydrogen power generation system 1000.
[0179] (2) For fuel cell module 3, the heat emitted by fuel cell module 3 during operation can be effectively utilized to heat hydrogen storage cylinder 221 or other links that require heat energy, thereby improving the utilization rate of waste heat and greatly improving the overall utilization rate of energy.
[0180] (4) Regarding the combination of hydrogen storage module 2, fuel cell module 3 and flow guiding module 1, on the one hand, through the highly integrated design concept, various functional modules are rationally integrated and optimized in layout. On the other hand, by combining hydrogen storage module 2, fuel cell module 3 and flow guiding module 1 in a compact and orderly manner, the overall volume and weight of hydrogen power generation system 1000 are greatly reduced, making it easier to install, transport and maintain. On the other hand, by combining fuel cell module 3, waste heat recovery can be achieved, further reducing heating energy consumption.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application.
