Description

Technical Field

[0001] This utility model relates to the field of hydrogen energy storage technology, specifically to a hydrogen power generation device. 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 equipment 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 equipment. 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 hydrogen power generation equipment 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. In integrated solid-state hydrogen storage devices, hydrogen storage cylinders are usually placed vertically with the bottle opening facing upwards. This results in a limited effective contact area between the hydrogen storage alloy and hydrogen gas because the alloy cannot be horizontally unfolded, making it difficult to improve hydrogen release efficiency. Furthermore, the residual heat of the fuel cell stack inside the hydrogen storage chamber has a short residence time and poor utilization of the residual heat, which also makes it difficult to improve hydrogen release efficiency.

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

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide a hydrogen power generation device that can solve the problems of high manufacturing difficulty and cost, heavy weight making transportation difficult, difficult maintenance, and difficulty in improving hydrogen release efficiency in the prior art.

[0009] To achieve the above and other objectives, this utility model is implemented through the following technical solution: This utility model proposes a hydrogen power generation device, including a fuel cell module and a hydrogen storage tank module arranged sequentially from left to right; the fuel cell module is provided with at least one fuel cell stack and corresponding electrical devices serving the fuel cell stack; the hydrogen storage tank module is provided with multiple gas cylinder chambers arranged in a matrix array and horizontally, and the gas cylinder chambers are connected to the fuel cell stack and the hydrogen storage tank gas circuits respectively through pressure reducing valves; the heat dissipation module of the fuel cell module is horizontally offset from the air outlet of the hydrogen storage tank module.

[0018] In one embodiment, each gas cylinder chamber is equipped with an indicator light, the light-emitting part of which is disposed on one side of the hydrogen storage module to indicate the status of the hydrogen storage cylinder in the gas cylinder chamber; a display screen, a stop button, and a start button are disposed on the upper surface of the fuel cell module; and a handle is disposed on the outer side of the housing of the hydrogen storage module.

Therefore, it should not be construed as a limitation of the invention.

[0045] (Example 1)

[0046] like Figure 1-4 As shown, this utility model provides a hydrogen power generation device, including a fuel cell module 100 and a hydrogen storage module 200 fixedly connected from left to right; the fuel cell module 100 is provided with at least one fuel cell stack 132. Figure 8 and Figure 9 Only the mounting screws for the fuel cell stack cells are shown (the cells themselves are not shown), along with the corresponding electrical devices serving the fuel cell stack 132. The hydrogen storage module 200 contains multiple horizontally arranged gas cylinder chambers 220 in a matrix array. Each gas cylinder chamber 220 includes a pressure reducing valve 221. The outlet of the pressure reducing valve 221 is connected to the gas path of the fuel cell stack 132, and the inlet of the pressure reducing valve 221 is detachably connected to the valve of the hydrogen storage cylinder 300 via a quick-connect female connector. Specifically, the gas cylinder chambers 220 are horizontally positioned within the hydrogen storage module 200 along the central axis of the pressure reducing valve 221. Because the gas cylinder chambers 220 are 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.

[0047] A heat dissipation module 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 on the right. 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 heat dissipation module 131, the hydrogen release efficiency of the hydrogen storage tank 300 can be improved.

[0048] Furthermore, as shown in Figure 10, in order 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 heat dissipation module 131 of the fuel cell module 100 and the air outlet 202 of the hydrogen storage module 200 can be horizontally offset. Specifically, the fuel cell stack 132 and its heat dissipation module 131 of the fuel cell module 100 are positioned near the upper end of the housing 110; specifically, the heat dissipation module 131 of the fuel cell module 100 is horizontally positioned on the upper right end face of the fuel cell module 100 and extends into the hydrogen storage module 200 to conduct waste heat from the fuel cell stack 132 to the hydrogen storage module 200. The air outlet 270 of the hydrogen storage module 200 is elongated and horizontally positioned on the lower edge of the right end face of the hydrogen storage module 200. During the operation of the fuel cell stack 132, the waste heat generated by the reaction in the fuel cell stack 132 is blown into the hydrogen storage module 200 through the heat dissipation module 131. The hot air flows from left to right and from top to bottom along a preset path within the cavity, allowing the hot air to come into contact with the hydrogen storage tank 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 air outlet 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 assembly from top to bottom, reducing the heating burden on the heating elements, lowering the power consumption of the heating elements, improving the overall energy efficiency of the system, and achieving the goal of energy cascade utilization.

[0049] In this embodiment, the cylinder chamber 220 is divided into at least two cylinder groups. The pressure reducing valves 221 within each cylinder group are connected in series, and each cylinder group can independently supply hydrogen to the fuel cell stack 132. Specifically, this embodiment has a total of nine cylinder chambers 220 and nine corresponding hydrogen storage cylinders 300. Three hydrogen storage cylinders 300 in the same row are connected in series to form one cylinder group, meaning the pressure reducing valves 221 of the corresponding three cylinder chambers 220 are connected in series; the three cylinder groups are designed to operate in parallel. Multiple cylinder groups can simultaneously supply hydrogen to the fuel cell stack 132 of the fuel cell module 100, or they can sequentially and individually supply hydrogen to the fuel cell stack 132 of the fuel cell module 100. In this embodiment, the fuel cell stack 132 is provided with one fuel cell stack 132, equipped with multiple intake solenoid valves (each gas cylinder group is independently equipped with one intake solenoid valve) and one exhaust solenoid valve 138. The specific route for supplying hydrogen from the gas cylinder group to the fuel cell stack 132 is as follows: the output hydrogen of each gas cylinder group after being regulated by the pressure reducing valve 221 is collected and merged through the intake solenoid valve and then transported to the fuel cell module 100 through the manifold section to supply hydrogen to the fuel cell stack 132. 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 the exhaust solenoid valve 138 and discharged from the system from the exhaust outlet.

[0050] Furthermore, to optimize the heat transfer path of the fuel cell module and make the heat exchange process more efficient, a support plate 211 with multiple through holes 211a can be installed inside the hydrogen storage module 200. The support plate 211 can be fixedly connected to the gas cylinder chamber 220 and is arranged perpendicular to the axis of the gas cylinder chamber 220 on the side where the pressure reducing valve 221 is connected to the hydrogen supply pipeline. The multiple through holes 211a on the support plate 211 are arranged at the positions of the pressure reducing valves 221 of the gas cylinder group closest to the heat dissipation module 131. In this embodiment, the multiple through holes 211a are arranged laterally at equal intervals on the upper part of the support plate 211, respectively corresponding to the positions of the pressure reducing valves 221 of the uppermost gas cylinder group, for passing through the hydrogen supply pipeline connecting the pressure reducing valve 221 and the air inlet of the fuel cell stack 132 and allowing hot air to circulate.

[0051] Furthermore, in order to allow the waste heat generated by the fuel cell stack 132 to directly enter the hydrogen storage module 200 with almost no loss and improve the utilization rate of the waste heat of the stack, a first baffle 212 is provided between the fuel cell module 100 and the support plate 211. The left and right ends of the first baffle 212 are located below the heat dissipation module 131 and the through hole 211a, respectively.

[0052] Furthermore, when multiple gas cylinder groups sequentially supply hydrogen to the fuel cell stack 132 of the fuel cell module 100 in a top-to-bottom order, in order to optimize the waste heat conduction path and make the heat exchange process of sequential hydrogen supply more efficient, a second baffle 213 can be set between the gas cylinder groups. The length of the second baffle 213 is less than the length of the gas cylinder chamber 220, and two adjacent second baffles 213 are staggered, so that the flow direction of hot air is Z-shaped from the through hole 211a to the air outlet 202. Specifically, the left end of the second baffle 213 closest to the through hole 211a is fixed to the support plate 211, so that after the hot air enters the top row of gas cylinders, it must first flow to the right, and then flow downward in the area of ​​the next row of gas cylinders that is not blocked by the second baffle 213. The right end of the second baffle 213 below the next row of gas cylinders is fixed to the inside of the right end face of the hydrogen storage module 200, so that after the hot air enters the next row of gas cylinders, it must first flow to the left. By arranging the second baffles 213 in a staggered manner as described above, the flow direction of the hot air can be made to be Z-shaped from the through hole 211a to the air outlet 202.

[0053] The advantages of adopting the above-mentioned specific flow design are as follows: when using gas cylinder groups for hydrogen supply in a top-to-bottom sequence, the heat can be concentrated on heating the top row of gas cylinder groups first, ensuring the hydrogen release efficiency of the top row of gas cylinder groups. At the same time, the waste heat can be used in stages to preheat the lower row of gas cylinder groups waiting to be supplied with hydrogen, reducing the time that heating elements need to be activated during the entire hydrogen supply process, thereby reducing the energy consumption of the system during hydrogen release. In addition, the alternating hydrogen supply allows the hydrogen storage cylinders in the idle gas cylinder groups to have a certain period of time to stand still and automatically recover their temperature. The initial pressure of the hydrogen storage cylinders after standing still is higher, and they can be used for a period of time without the need for heating elements. At the same time, by rotating and standing still multiple times, the release of hydrogen in the hydrogen storage cylinders can be maximized, avoiding frequent replacement of hydrogen storage cylinders.

[0054] It should be noted that in other embodiments, the heat dissipation module 131 and the air outlet 202 can also be arranged longitudinally. In this case, the hydrogen storage cylinders 300 in the same column are connected in series to form a gas cylinder group, and the positions of the through hole 211a, the first baffle 212 and the second baffle 213 are also changed to be arranged longitudinally according to the positions of the heat dissipation module 131 and the air outlet 202.

[0055] Furthermore, to ensure the safety and stability of the hydrogen power generation equipment, 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 correctly, an indicator light 260, such as an LED, can be configured in each cylinder chamber 220 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:

[0056] (1) If the status indicator light 260 is not lit, it means that the hydrogen storage cylinder 300 is not inserted.

[0057] (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.

[0058] (3) The status indicator light 260 flashes green, indicating that the hydrogen storage cylinder 300 is in use;

[0059] (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.

[0060] 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.

[0061] Please combine Figure 5 and Figure 6 To facilitate the replacement of the hydrogen storage cylinder 300, the hydrogen storage cylinder 300 is connected to the pressure reducing valve 221 in a detachable sealed manner within the cylinder chamber 220. Specifically, the hydrogen storage cylinder 300 has a cylinder valve (i.e., a quick-connect male connector) at its opening; the pressure reducing valve 221 has a quick-connect female connector with an opening and closing sliding sleeve that mates with the quick-connect male connector; and a rapid hydrogen exchange device 250 is installed within the cylinder chamber 220 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 221.

[0062] Specifically, the gas cylinder chamber 220 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 from left to right. 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 221 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 of the gas cylinder chamber 220 to the outside of the gas cylinder chamber 220, and can slide horizontally relative to the hydrogen storage cylinder 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 220, and can move together with the push rod 251. The lower part of the shift fork 252 is engaged with the opening and closing sliding sleeve. 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 220, 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 220. 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.

[0063] 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 221, 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 220, and gently push the bottom of the cylinder into cylinder chamber 220 to install the cylinder valve of hydrogen storage cylinder 300 onto quick-connect female head of pressure reducing valve 221, completing the cylinder replacement operation.

[0064] Furthermore, in order to improve the overall stability of the gas cylinder chamber 220, 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 efficient flow of hot air between the gas cylinder chambers 220.

[0065] Furthermore, such as Figure 7As 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 270 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 270 is communicatively connected to the indicator light 260. When the detection signal from the modular sensing unit 270 is transmitted to the control mainboard, the control mainboard 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).

[0066] Furthermore, such as Figure 7 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 280 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 280 is heating paper, disposed on the arc-shaped plate 233.

[0067] Please combine Figure 1 , Figure 8 and Figure 9 The fuel cell module 100 includes a housing 110 and a left cover 120, which can be opened. Multiple air inlets 121 arranged in a matrix are located on the left cover 120. The upper surface of the housing 110 is equipped with a display screen 111 for displaying equipment operating status information, a stop button 112 for controlling equipment shutdown and startup, and a start button. The housing 110 contains a fuel cell stack 132 and corresponding electrical devices serving the fuel cell stack 132. These electrical devices include, for example, a control motherboard 133, a step-down DC converter 134, a current sensor 135, a relay 136, a pressure sensor 137, an intake solenoid valve, an exhaust solenoid valve 138, a boost DC converter, and a DC cooling device 139 mounted on the boost DC converter. The specific installation positions of each electrical device can be designed and arranged as needed, and are not limited here. The connection relationships and working principles of each electrical device are common knowledge to those skilled in the art and will not be described in detail here.

[0068] Furthermore, such as Figure 1 As shown, in order to facilitate the overall transfer of the hydrogen power generation equipment, a handle 201 can be provided on the outer side of the housing of the hydrogen storage module 200.

[0069] (Example 2)

[0070] The difference between this embodiment and Embodiment 1 is that in this embodiment, the gas cylinder chambers 220 are not grouped, and hydrogen is supplied to the fuel cell stack 132 of the fuel cell module 100 simultaneously. In this case, the number of through holes 211a on the support plate 211 can be equal to the number of gas cylinder chambers 220, that is, through holes 221a are respectively provided at the positions of the pressure reducing valves 221, and the design of the first baffle 212 and the second baffle 213 is omitted, so that the hot air blown out by the heat dissipation module 131 can simultaneously heat each hydrogen storage cylinder 300. Because the heat dissipation module 131 and the air outlet 202 are horizontally staggered, the waste heat generated by the reaction of the fuel cell stack 132 is blown into the hydrogen storage module 200 through the heat dissipation module 131. The hot air can also flow from left to right and from top to bottom along a preset path in the cavity. The air outlet 270 on one side can increase the path of hot air from top to bottom in the cavity, making the heat exchange more complete. It can also heat the gas cylinder group in a gradient from top to bottom, reduce the heating burden of the heating element, reduce the power consumption of the heating element, improve the overall energy efficiency of the system, and achieve the goal of energy cascade utilization.

[0071] In summary, the multiple hydrogen storage cylinders 300 of the hydrogen power generation equipment provided by this utility model can be quickly installed and removed from the gas cylinder chamber 220 via quick-connect female connectors, reducing the overall manufacturing and installation difficulty of the equipment. During transportation, the hydrogen storage cylinders 300 can be omitted, reducing the system weight and transportation difficulty. Simultaneously, because the gas cylinder chamber 220 is horizontally placed, the hydrogen storage alloy inside the gas cylinder can also unfold horizontally during hydrogen release. Compared to vertically placed hydrogen storage cylinders, the hydrogen storage alloy has a larger effective contact area with hydrogen, resulting in higher hydrogen release efficiency. Furthermore, the horizontally staggered arrangement of the heat dissipation module 131 and the air outlet 202 increases the residence time of the residual heat from the fuel cell stack within the hydrogen storage chamber, improving the utilization of residual heat and further enhancing hydrogen release efficiency. This utility model is adaptable to forklifts, sightseeing vehicles, backup power supplies, etc., with a wide range of applications and strong adaptability.

[0072] 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.
