Description

Technical Field

[0001] This utility model relates to the field of hydrogen energy storage technology, specifically to a hydrogen power generation system. Background Technology

[0002] Hydrogen energy is a clean energy source for the 21st century. Existing hydrogen storage methods include high-pressure gaseous, cryogenic liquid, organic liquid, and metallic (non-metallic) solid-state storage, each corresponding to its respective application area. Among these, solid-state hydrogen storage technology offers advantages such as high storage capacity, low operating pressure, and good safety, making it widely applicable in various stationary, mobile, and portable power sources, such as electric bicycles, electric motorcycles, forklifts, sightseeing vehicles, and backup power supplies.

[0003] In existing technologies, the hydrogen storage cylinders used for solid-state hydrogen storage are small in capacity and size. For equipment requiring a certain amount of hydrogen, such as forklifts, sightseeing vehicles, and backup power supplies, more hydrogen storage cylinders need to be installed in the hydrogen power generation system to ensure their normal operation. Typically, in practice, an integrated solid-state hydrogen storage device structure is designed and manufactured based on the hydrogen consumption of the equipment (i.e., the hydrogen storage cylinders are pre-fixed in the solid-state hydrogen storage device), and then the solid-state hydrogen storage device is directly installed in the hydrogen power generation system. When the gas in the solid-state hydrogen storage device is used up, the entire device is removed for refilling. This method of using an integrated solid-state hydrogen storage device in a hydrogen power generation system has the following disadvantages:

[0004] 1. The integrated solid hydrogen storage device requires the integration of a large number of hydrogen storage cylinders, which has a relatively complex structure and is difficult to manufacture. In particular, the connection between the hydrogen storage cylinders is more complicated, which leads to an increase in the overall production cost.

[0005] 2. Large-scale solid-state hydrogen storage devices are heavy and require specific handling tools and lifting equipment for transportation;

[0006] 3. When the hydrogen storage cylinder or pipeline in the integrated solid hydrogen storage device malfunctions or is damaged, it is difficult to inspect and repair the damaged point. Once there is a malfunction or damage, the entire integrated solid hydrogen storage device must be shut down.

[0007] Given the aforementioned shortcomings, it is particularly important to improve the structure of hydrogen power generation systems to facilitate manufacturing, installation, transportation, and maintenance. Utility Model Content

[0014] In one embodiment, the gas cylinder chamber further includes reinforcing plates disposed on both sides of the integrated bracket along its length; ventilation holes are provided on the reinforcing plates.

[0015] In one embodiment, a modular sensing unit is provided on the reinforcing plate or integrated bracket, the modular sensing unit being used to detect whether the hydrogen storage cylinder is installed in place.

[0016] In one embodiment, the modular sensing unit includes one or more of a weight sensor, a displacement sensor, and an electric field sensor.

[0017] In one embodiment, the arc-shaped plate of the integrated bracket and / or the circumferential arrangement of the hydrogen storage bottle are provided with heating elements for heating the hydrogen storage bottle when hydrogen is released from the hydrogen storage bottle.

[0018] In one embodiment, the air intake direction of the fuel cell module is perpendicular to the air outlet direction of the hydrogen storage module.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The hydrogen power generation system provided by this utility model allows multiple hydrogen storage cylinders to be quickly installed and removed from the gas cylinder chamber via quick-connect female connectors. The pressure reducing valve of the gas cylinder chamber is connected to the gas circuit of the fuel cell stack through a series-parallel connection. This allows the hydrogen storage cylinders installed in the gas cylinder chamber to be divided into multiple gas cylinder groups, enabling group installation and hydrogen supply, which reduces the overall manufacturing and installation difficulty of the system. During transportation, the hydrogen storage cylinders can be removed, reducing the system weight and transportation difficulty. At the same time, hydrogen can be supplied in groups.

[0038] Please see Figures 1-9 The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0039] It should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are only used to complement the content disclosed in the specification for those skilled in the art to understand and read, and are not intended to limit the conditions under which this utility model can be implemented. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and purposes that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model.

[0040] In this invention, the serial numbers assigned to components, such as "first," "second," etc., are merely used to distinguish the described objects and have no sequential or technical meaning. The term "connection" in this invention, unless otherwise specified, includes both direct and indirect connections. The terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, encompassing not only the listed elements but also other elements not expressly listed.

[0041] In this utility model, the terms "upper," "lower," "left," "right," "front," and "rear," which indicate orientation or positional relationships, are all based on the appendix. Figure 1 This description is provided only for the purpose of clearly describing the invention and is not intended to indicate or imply that the structures or components referred to must have a specific orientation or be constructed in a specific orientation. Therefore, it should not be construed as a limitation of the invention.

[0042] like Figures 1-3As shown, this utility model provides a hydrogen power generation system, including a hydrogen storage module 200 and a fuel cell module 100 arranged sequentially from left to right; the fuel cell module 100 contains at least one fuel cell stack 132 and corresponding electrical devices serving the fuel cell stack 132; the hydrogen storage module 200 contains multiple gas cylinder chambers 210 arranged in a matrix array and horizontally, each gas cylinder chamber 210 including a pressure reducing valve 220 (see...). Figure 6 The outlet of the pressure reducing valve 220 is connected to the gas path of the fuel cell stack 132, and the inlet of the pressure reducing valve 220 is detachably connected to the valve of the hydrogen storage cylinder 300 via a quick-connect female connector; the gas cylinder chamber 210 is divided into at least two gas cylinder groups, and the pressure reducing valves 220 in each gas cylinder group are connected in series, and each gas cylinder group can independently supply hydrogen to the fuel cell stack 132.

[0043] Specifically, the gas cylinder chamber 210 is horizontally positioned within the hydrogen storage module 200 along the central axis of the pressure reducing valve 220. Because the gas cylinder chamber 210 is horizontally positioned, the hydrogen storage alloy can also be horizontally deployed within the gas cylinder during hydrogen release. Compared to the vertically positioned hydrogen storage cylinder 300, the hydrogen storage alloy has a larger effective contact area with hydrogen, resulting in higher hydrogen release efficiency.

[0044] like Figures 1-5 As shown, in this embodiment, a total of 8 gas cylinder chambers 210 and corresponding 8 hydrogen storage cylinders 300 are provided. Two hydrogen storage cylinders 300 in the same row are connected in series to form a gas cylinder group, that is, the pressure reducing valves 220 of the corresponding two gas cylinder chambers 210 are connected in series; the 4 gas cylinder groups are designed to operate in parallel. The 4 gas cylinder groups can supply hydrogen to the fuel cell stack 132 of the fuel cell module 100 simultaneously, or they can supply hydrogen to the fuel cell stack 132 of the fuel cell module 100 individually in the order of the 1st to the 4th group. In this embodiment, three fuel cell stacks 132 are provided, each independently equipped with an intake solenoid valve 135 and an exhaust solenoid valve 136. The specific route for supplying hydrogen from the gas cylinder group to the fuel cell stack 132 is as follows: the output hydrogen from each gas cylinder group, after being regulated by the pressure reducing valve 220, is concentrated and then transported to the fuel cell module 100 through the manifold section after being collected by the three-way valve 292. Then, the hydrogen is precisely divided into three paths by the three-way valve 292 in the fuel cell module 100, and connected to three independent intake solenoid valves 135 respectively, so that the three fuel cell stacks 132 can generate electricity in parallel using hydrogen. The remaining hydrogen that does not participate in the reaction after the fuel cell stack 132 generates electricity and the water generated by the electrochemical reaction are collected in the exhaust pipeline through their respective exhaust solenoid valves 136 and discharged from the system through the exhaust outlet.

[0045] It should be noted that when it is not necessary for all three fuel cell stacks 132 to operate simultaneously, the corresponding fuel cell stack 132 can be shut down by closing the intake solenoid valve 135 and relay 134 of the corresponding fuel cell stack 132. At this time, the hydrogen entering the fuel cell module 100 is evenly divided into the same number of paths as the number of fuel cell stacks 132 in use.

[0046] Furthermore, to ensure the safety and stability of the hydrogen power generation system, all hydrogen storage cylinders 300 in each cylinder group must be synchronously connected. To facilitate identification of whether the hydrogen storage cylinders 300 are connected, an indicator light 260, such as an LED, can be configured in each cylinder chamber 210 to indicate the status of the hydrogen storage cylinders 300 within the chamber. The indicator light 260 is electrically connected to the control mainboard 137 within the fuel cell module 100, and its light-emitting part is located on one side of the hydrogen storage module 200 for easy observation by operators. When the hydrogen power generation system is first started, the fuel cell stack 132 has not yet generated electricity, and the lithium battery within the fuel cell module 100 supplies power to the indicator light 260; after the fuel cell stack 132 begins operation, the electricity generated by the fuel cell stack 132 supplies power to the indicator light 260 via the control mainboard 137. In this embodiment, the indicator light 260 has four states to indicate the four states of the hydrogen storage cylinders 300, as follows:

[0047] (1) If the status indicator light 260 is not lit, it means that the hydrogen storage cylinder 300 is not inserted.

[0048] (2) The status indicator light 260 is always green, which means that the hydrogen storage cylinder 300 is in the state of meeting the hydrogen supply conditions. To meet the hydrogen supply conditions, three conditions must be met at the same time: the hydrogen storage cylinder 300 is inserted; the pressure inside the cylinder reaches the hydrogen supply pressure; and the newly inserted hydrogen storage cylinder 300 is full of gas by default, which means it is in the state of meeting the hydrogen supply conditions.

[0049] (3) The status indicator light 260 flashes green, indicating that the hydrogen storage cylinder 300 is in use;

[0050] (4) The status indicator light 260 is always red, which means that the hydrogen storage cylinder 300 is empty, that is, the pressure inside the cylinder is less than the hydrogen supply pressure.

[0051] It should be noted that the four states of the indicator light 260 provided in this embodiment are only examples. The indicator light 260 can also use other light colors, or display Chinese characters or other required designs to indicate the four states of the hydrogen storage cylinder 300.

[0052] Furthermore, to improve the stability of the piping layout within the system, a three-way valve 292 for fixing the hydrogen supply pipeline 291 and a support plate 280 for facilitating the gas pipe connection layout can be installed within the hydrogen storage module 200. One end of the manifold section of the hydrogen supply pipeline 291 extends into the fuel cell module 100 and connects to the gas path of the fuel cell stack 132 within it. The other end is diverted through the three-way valve 292 and sequentially connected to the pressure reducing valve 220 via gas pipes. The support plate 280 has through holes 281 for passing through gas pipes. The support plate 280 can also be fixedly connected to the gas cylinder chamber 210 and is arranged perpendicular to the axis of the gas cylinder chamber 210 on the side where the pressure reducing valve 220 connects to the hydrogen supply pipeline 291.

[0053] Please combine Figure 6 and Figure 7 To facilitate the replacement of the hydrogen storage cylinder 300, the hydrogen storage cylinder 300 is connected to the pressure reducing valve 220 in a detachable sealed manner within the cylinder chamber 210. Specifically, the hydrogen storage cylinder 300 is equipped with a cylinder valve (quick-connect male connector) at its opening; the pressure reducing valve 220 is equipped with a quick-connect female connector, which has an opening and closing sliding sleeve that mates with the quick-connect male connector. A rapid hydrogen exchange device 250 is installed within the cylinder chamber 210 to drive the movement of the opening and closing sliding sleeve, thereby connecting and disconnecting the hydrogen storage cylinder 300 and the pressure reducing valve 220.

[0054] Specifically, the gas cylinder chamber 210 includes an integrated support 230, a fixing block 240, and a rapid hydrogen exchange device 250. The integrated support 230 includes a fixing block support 231, a first perforated plate 232, an arc-shaped plate 233, and a second perforated plate 234, which are sequentially fixedly connected in a front-to-back direction. The fixing block support 231 is located at the bottom of the first perforated plate 232. The first perforated plate 232, the arc-shaped plate 233, and the second perforated plate 234 together form a hydrogen storage cylinder 300 support, respectively supporting the cylinder opening, body, and bottom of the hydrogen storage cylinder 300. The pressure reducing valve 220 is mounted on the integrated support 230 via the fixing block 240. The rapid hydrogen exchange device 250 is mounted on the integrated support 230, specifically on the hydrogen storage cylinder 300 support, and is positioned away from the arc-shaped plate 233. The rapid hydrogen exchange device 250 includes a push rod 251, a fork 252, and a button 253. The push rod 251 has its two ends respectively mounted on the first perforated plate 232 and the second perforated plate 234, extending from the inside to the outside of the gas cylinder chamber 210, and can slide horizontally relative to the hydrogen storage tank 300 support. The upper part of the shift fork 252 is fixedly mounted on the end of the push rod 251 located inside the gas cylinder chamber 210, and can move together with the push rod 251. The lower part of the shift fork 252 is engaged on the outer edge of the quick-connect female of the pressure reducing valve 220. The shift fork 252 is mounted on the guide shaft 255, which is located on the first perforated plate 232, ensuring that the shift fork 252 moves in a fixed direction and preventing rotational deviation. The button 253 is located on the end of the push rod 251 located outside the gas cylinder chamber 210, and protrudes from the front end of the hydrogen storage module 200. Pressing the button 253 can drive the push rod 251 to slide inward into the gas cylinder chamber 210. A limit ring 254 is also provided on the push rod 251 to limit the displacement range of the push rod 251. A reset spring can also be provided between the limit ring 254 and the first perforated plate 232 to facilitate the reset of the push rod 251 after use.

[0055] When the hydrogen storage cylinder 300 needs to be replaced, pressing button 253 causes push rod 251 to drive shift fork 252 to push opening and closing sleeve to the end away from the cylinder valve, so that quick-connect female head automatically pops out the cylinder valve, contacts the connection between hydrogen storage cylinder 300 and pressure reducing valve 220, and automatically pops out the bottom of hydrogen storage cylinder 300 for easy removal; then, insert the hydrogen storage cylinder 300 filled with hydrogen into cylinder chamber 210, and gently push the bottom of the cylinder into cylinder chamber 210 to install the cylinder valve of hydrogen storage cylinder 300 onto quick-connect female head of pressure reducing valve 220, completing the cylinder replacement operation.

[0056] Furthermore, in order to improve the overall stability of the gas cylinder chamber 210, a reinforcing plate 235 can be set on each of the left and right sides of the integrated bracket 230. The reinforcing plate 235 is provided with ventilation holes to optimize the air circulation path and ensure smooth circulation of hot air between the gas cylinder chambers 210.

[0057] Furthermore, such as Figure 8As shown, to accurately determine the position of the hydrogen storage cylinder 300 and improve the safety and reliability of the system, a modular sensing unit 236 can be installed on the reinforcing plate 235 or the integrated bracket 230. Optional weight sensors, displacement sensors, and electric field sensors (such as anti-interference capacitive proximity sensors) can be installed. By collecting data on mass changes, mechanical deformation, or spatial electric field disturbances in real time, the position of the hydrogen storage cylinder 300 can be accurately determined. The modular sensing unit 236 is communicatively connected to the indicator light 260. When the detection signal from the modular sensing unit 236 is transmitted to the control mainboard 137, the control mainboard 137 determines whether the hydrogen storage cylinder 300 is inserted. If not inserted, the indicator light 260 is turned off; if inserted, the indicator light 260 turns green (newly inserted hydrogen storage cylinder 300 is assumed to meet hydrogen supply conditions).

[0058] Furthermore, such as Figure 8 As shown, to ensure sufficient heat is provided to the hydrogen storage alloy during hydrogen release from the hydrogen storage cylinder 300, facilitating hydrogen release and ensuring the hydrogen release efficiency of the hydrogen storage cylinder 300, a heating element 237 can be provided on the arc-shaped plate 233 of the integrated support 230 and / or circumferentially around the hydrogen storage cylinder 300 to heat the hydrogen storage cylinder 300 during hydrogen release. In this embodiment, the heating element 237 is heating paper, disposed on the arc-shaped plate 233.

[0059] Please combine Figure 1 and Figure 2 The fuel cell module 100 includes a housing 110 and a front cover 120, which can be opened. The front cover 120 has multiple air inlets 121 arranged in a matrix. The housing 110 includes a fuel cell stack 132, a step-down DC converter, a step-up DC converter, a DC cooling device 133, a current sensor, a relay 134, a pressure sensor, an intake solenoid valve 135, an exhaust solenoid valve 136, and a control mainboard 137.

[0060] Please combine Figure 3 and Figure 9 A fan 131 is provided on the back of the fuel cell stack 132. On the one hand, it is used to draw outside air into the air channel of the fuel cell stack 132 to cause the oxygen to undergo a reduction reaction. On the other hand, it is used to conduct the hot air generated by the fuel cell stack 132 during operation to the hydrogen storage tank module 200 at the rear. Because the hydrogen storage tank 300 absorbs heat when releasing hydrogen, the temperature drop inside the hydrogen storage tank will reduce the hydrogen release efficiency of the hydrogen storage tank 300. Therefore, by conducting the hot air generated by the fuel cell stack 132 during operation to the hydrogen storage tank module 200 through the fan 131, the hydrogen release efficiency of the hydrogen storage tank 300 can be improved.

[0061] Furthermore, to increase the residence time of waste heat from the fuel cell module 100 within the hydrogen storage module 200, improve waste heat utilization, and further ensure the hydrogen release efficiency of the hydrogen storage cylinder 300, the exhaust direction of the hydrogen storage module 200 can be set perpendicular to the intake direction of the fuel cell module 100. Specifically, as follows... Figure 1 and Figure 9 As shown, the fan 131 of the fuel cell module 100 is positioned near the pressure reducing valve 220; the heat dissipation channel 270 of the hydrogen storage module 200 is elongated and horizontally positioned at the bottom edge of the front face of the hydrogen storage module 200. This allows the waste heat generated by the fuel cell stack 132 during operation to be blown into the hydrogen storage module 200 by the fan 131. The hot air circulates within the cavity along a preset path from right to left, from back to front, and from top to bottom, ensuring that the waste heat airflow preferentially contacts the hydrogen storage alloy material near the valve of the hydrogen storage cylinder 300. Utilizing the heat absorption and hydrogen release properties of the alloy material, the process of hydrogen release through thermal dissociation is accelerated. The single-sided heat dissipation channel 270 increases the downward path of the hot air within the cavity, resulting in more thorough heat exchange. It also allows for gradient heating of the gas cylinder group from group 1 to group 4, reducing the heating burden on the heating elements, lowering their power consumption, improving the overall energy efficiency of the system, and achieving the goal of energy cascade utilization.

[0062] In other embodiments, the fan 131 can also be positioned centrally within the fuel cell module 100, but this arrangement would encroach on the installation space of other electrical components, resulting in low space utilization. Alternatively, the fan 131 can be positioned on the side furthest from the pressure reducing valve 220, in which case the waste heat provides better heating to the cylinder.

[0063] In summary, the hydrogen storage cylinders 300 of the hydrogen power generation system provided by this utility model can be quickly installed and removed from the gas cylinder chamber 210 via quick-connect female connectors. Furthermore, the pressure reducing valve 220 of the gas cylinder chamber 210 is connected to the gas circuit of the fuel cell stack 132 via a series-parallel connection. This allows the hydrogen storage cylinders 300 installed in the gas cylinder chamber 210 to be divided into multiple cylinder groups, enabling group installation and hydrogen supply, thus reducing the overall manufacturing and installation difficulty of the system. During transportation, the hydrogen storage cylinders 300 can be omitted, reducing the system weight and transportation difficulty. Simultaneously, hydrogen can be supplied in groups; when one group runs out of hydrogen or malfunctions, other groups can still supply hydrogen. The faulty group can be identified without shutting down the system, and the hydrogen storage cylinders 300 within that group can be replaced and repaired, thereby increasing the system's continuous operating time. It is compatible with forklifts, sightseeing vehicles, backup power supplies, etc., and has a wide range of applications and strong adaptability.

[0064] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
