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. 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 either lack sufficient heat from the solid-state hydrogen storage tanks, affecting hydrogen release, or require additional electricity to electrically heat the tanks, resulting in low system efficiency. Furthermore, existing hydrogen power generation systems typically integrate only a fuel cell stack, controller, and solid-state hydrogen storage tank. This leads to problems such as a limited number of fuel cell stacks, low output power, inefficient layout, insufficient capacity to accommodate multiple hydrogen storage tanks, and poor utilization of waste heat from the stack, ultimately failing to meet the actual power demands of large-scale machinery such as agricultural equipment.

[0015] In one embodiment, excess hydrogen and water generated during power generation from at least one of the fuel cell stacks are output from the outlet of each fuel cell stack, and after being controlled by a corresponding exhaust control valve, they are combined into one path and output to the hydrogen storage module through a pipeline.

[0034] 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.

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.

[0036] 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 2 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.

[0037] like Figure 1 and Figure 2 As shown, this utility model provides a hydrogen power generation system that integrates at least one fuel cell stack 130 and multiple hydrogen storage devices 240, which can meet the actual power needs of large-scale machinery such as high-power agricultural equipment. Specifically, the hydrogen power generation system is structurally designed to include only two interconnected and gas-connected modules: a fuel cell module 100 and a hydrogen storage module 200. The fuel cell module 100 is used to install and arrange multiple fuel cell stacks 130 and corresponding electrical devices serving the fuel cell stacks 130. The hydrogen storage module 200 is used to install and arrange multiple hydrogen storage devices 240, which are connected to the fuel cell stacks 130 via gas lines to supply gas to the fuel cell stacks 130.

[0038] like Figure 2 and Figure 3 As shown, the fuel cell module 100 includes a first housing, and a control main board 150, a lithium battery, a DC step-down device 180, multiple fuel cell stacks 130, multiple flow fans 140, multiple DC boost devices 160, multiple solenoid valves 133, and multiple current sensors 132 disposed in the first housing.

[0039] The first housing includes a box body 110 and a front cover 120 (air inlet hood). The front cover 120 has multiple first holes 121 arranged in a matrix array for air intake into the fuel cell stack 130 and heat dissipation from other electrical devices (such as the DC boost converter 160). The upper surface of the box body 110 is equipped with a display screen 111, a power button, and a start button. The display screen 111 is used to shut down the operating system and display the system's operating status. The power button controls the lithium battery to power the internal electrical devices such as the fuel cell stack 130, the control motherboard 150, and the solenoid valve 133. The start button controls the starting of the hydrogen fuel cell stack 130. It should be noted that the display screen 111, power button, and start button can also be omitted. When the hydrogen power generation system is installed on an agricultural vehicle or other vehicle, its power-on, start-up, and shutdown can be directly controlled via the vehicle's own motherboard, eliminating the need for manual control via buttons, the display screen 111, etc. The side of the box 110 is provided with a current output reserved hole 112 for connecting external electrical equipment (such as agricultural machinery, hydrogen-powered two-wheeled vehicles, vending machines and other types of electrical equipment).

[0040] like Figure 3 As shown, multiple fuel cell stacks 130 are arranged sequentially from top to bottom on the left side of the housing 110, and each fuel cell stack 130 is equipped with a flow guide fan 140 and a current sensor 132. Figure 3 Only four stack fastening rods 131 of the fuel cell stack 130 are shown; the specific structure of the fuel cell stack 130 is not shown. The stack fastening rods 131 are located inside the fuel cell stack 130 and are used to lock the multi-layered individual solar cells. After the multi-layered individual solar cells are stacked, they need to be pressed together using a hydraulic press, and then locked with screws and nuts to maintain the internal pressure between the components of the fuel cell stack 130. In this embodiment, there are three fuel cell stacks 130, therefore, there are also three flow guide fans 140 and three current sensors 132. Please refer to... Figure 5 and Figure 6A flow guide fan 140 is positioned directly behind the fuel cell stack 130. Through the perforation 113 on the rear end face of the housing 110, the flow guide fan 140 can extend out of the fuel cell module 100 and into the hydrogen storage module 200. The position of the flow guide fan 140 serves two purposes: firstly, it draws outside air into the airflow channels of the fuel cell stack 130, facilitating the reduction reaction of oxygen; secondly, it conducts the heat generated by the fuel cell stack 130 during operation to the hydrogen storage module 200, allowing the hydrogen storage device 240 to absorb heat when releasing hydrogen. A drop in temperature within the hydrogen storage module 200 reduces the hydrogen release efficiency of the hydrogen storage device 240. Therefore, conducting the hot air generated by the fuel cell stack 130 through the flow guide fan 140 to the hydrogen storage module 200 improves the hydrogen release efficiency of the hydrogen storage device 240. A current sensor 132 is positioned below the bottommost fuel cell stack 130 to detect whether the output current of the corresponding fuel cell stack 130 is normal. Furthermore, a temperature sensor can be integrated inside the fuel cell stack 130 to monitor the real-time temperature of the fuel cell stack 130.

[0041] like Figure 3 and Figure 4As shown, the control motherboard 150 is positioned at the top right of the housing 110 via a mounting frame 151, facilitating electrical connection with the display screen 111, power-on button, and start button on the upper surface of the housing 110. Below the control motherboard 150, from top to bottom, are arranged multiple DC boost converters 160, the number of which matches the number of fuel cell stacks 130, each corresponding to a fuel cell stack 130 on the left side. Each DC boost converter 160 is equipped with a cooling fan 161, which faces the front cover 120 and dissipates heat through the first hole 121 on the front cover 120. The control motherboard 150 and the multiple DC boost converters 160 are fixed to the inner right wall of the housing 110, leaving space behind them for mounting pressure sensors 170, DC step-down converters 180, multiple solenoid valves 133, and multiple relays 134. Specifically, the pressure sensor 170 and the DC step-down device 180 are located behind the control main board 150; the intake control valve 133a and exhaust control valve 133b of each fuel cell electric thruster are arranged near the intake and exhaust ports of the corresponding fuel cell stack 130, and are respectively connected to the intake and exhaust ports of the corresponding fuel cell stack 130; the pressure sensor 170 is used to detect the hydrogen pressure entering the fuel cell stack 130; the hydrogen entering the fuel cell stack 130 is provided by the hydrogen storage device 240, the intake control valve 133a can realize the on / off control of hydrogen, and the remaining hydrogen that has not participated in the reaction is discharged through the exhaust control valve 133b; both the intake control valve 133a and the exhaust control valve 133b can be solenoid valves 133. Each fuel cell electric propeller has a pair of relays 134, namely a positive relay and a negative relay. The positive and negative relays are arranged close to the positive and negative terminals of the corresponding fuel cell stack. The positive relay is used to control the on / off state of the positive terminal of the fuel cell electric propeller, and the negative relay is used to control the on / off state of the negative terminal of the fuel cell electric propeller.

[0042] After the fuel cell stack 130 generates electricity from hydrogen, the output power is first detected by the current sensor 132, and then transmitted to the DC boost converter 160. The DC boost converter 160 then transmits the power to the lithium battery (not shown in the figure, which can be installed in any available location inside the fuel cell module 100), the DC buck converter 180, and external electrical equipment. The lithium battery can be used as a starting battery to power the control board 150 and the fuel cell stack 130 when the user presses the power button. When the lithium battery is sufficiently charged, the output current of the DC boost converter 160 can be directly supplied to the external electrical equipment without being sent to the lithium battery. In addition, the lithium battery can also be used to store electrical energy and can supply power to external equipment when needed. Under certain circumstances, the DC boost converter 160 and the lithium battery can simultaneously output current to the same external electrical equipment. In other words, the hydrogen power generation system of this application can switch between different output modes according to the actual situation and the different electrical equipment it is adapted to (such as agricultural machinery, hydrogen-powered two-wheeled vehicles, vending machines and other types of electrical equipment). It can provide power to hydrogen-powered two-wheeled vehicles and provide reliable and stable power to vending machines, and has strong adaptability.

[0043] The DC step-down device 180 is connected to the control motherboard 150 and other internal electrical devices for power supply. The current after being stepped down by the DC step-down device 180 can power the control motherboard 150 and other internal electrical devices. The control motherboard 150 is communicatively connected to various internal devices such as the current sensor 132, temperature sensor, pressure sensor 170, flow guide fan 140, intake control valve 133a, and exhaust control valve 133b. The current sensor 132, temperature sensor, and pressure sensor 170 can feed back the collected data such as output current, stack temperature, and hydrogen pressure to the control motherboard 150, realizing real-time control of the intake control valve 133a and exhaust control valve 133b, as well as real-time control of the flow guide fan 140, thereby realizing the control of hydrogen output and power generation of the fuel cell stack 130.

[0044] like Figure 2 , Figure 6 and Figure 7 As shown, the hydrogen storage module 200 includes a second housing and multiple hydrogen storage devices 240 disposed within the second housing. The multiple hydrogen storage devices 240 are arranged in a matrix array and horizontally arranged within the second housing via a hydrogen storage tank 230, with the nozzles of the hydrogen storage devices 240 facing the fuel cell module 100. A handle 214 is provided on the side of the second housing for easy lifting and transport of the hydrogen power generation system. Figure 7 As shown, the first housing includes a partition plate 220 and a back plate 210 arranged in a matrix array between the partition plate 220 and the back plate 210, which are located from the fuel cell module 100 in order of proximity.

[0045] like Figure 9 As shown, the partition plate 220 is equipped with a pressure reducing valve 221, a one-way valve 222, a three-way valve 223, and heat conduction holes 224. The pressure reducing valve 221 is used to connect to the bottle neck of the hydrogen storage device 240. Each pressure reducing valve 221 is connected in series with a one-way valve 222. The three-way valve 223 is used to connect the one-way valves 222 in parallel. The heat conduction holes 224 are also arranged in a matrix array corresponding to multiple hydrogen storage devices 240, and are used to guide hot air into the containment space where the hydrogen storage devices 240 are located. They can be square holes, round holes, etc. After the flow fan 140 sprays the hot air from the fuel cell module 100 toward the hydrogen storage module 200, the hot air will enter the space between the flow fan 140 and the partition plate 220, from... Figure 6 As can be visually observed, in this embodiment, the hydrogen storage devices 240 in the second, third, and fourth columns are directly in front of the guide fan 140, while the hydrogen storage devices 240 in the first, fifth, sixth, and seventh columns are relatively far from the guide fan 140. Therefore, to heat each hydrogen storage device 240 more evenly, the size of the heat conduction holes 224 can be designed such that the size increases with distance from the guide fan 140. This compensates for the disadvantage of greater distance by increasing the size of the heat conduction holes 224, while smaller size heat conduction holes 224 prevent overheating of hydrogen storage devices 240 closer to the guide fan 140. In this embodiment, the heat conduction holes 224 in the same column are of the same size; the second column has the smallest size; the third to seventh columns all have larger sizes than the second column, with the size gradually increasing; the first column has the same size as the third column.

[0046] like Figure 8 As shown, the back panel 210 is provided with hydrogen storage port 211 and second hole 213. The hydrogen storage port 211 corresponds to multiple hydrogen storage chambers 230 arranged in a matrix array for taking out and putting in the hydrogen storage device 240. Each hydrogen storage port 211 is equipped with a bottle removal button 212, which is used to remove the hydrogen storage device 240 with one click. Multiple second holes 213 are located below the bottom row of hydrogen storage ports 211 for releasing the heat inside the hydrogen storage module 200 to the outside.

[0047] In summary, the power generation process of the hydrogen power generation system provided by this utility model is as follows: Hydrogen gas output from 28 hydrogen storage devices 240 (four rows and seven columns) passes through pressure reducing valves 221 and then converges into a main hydrogen supply pipe via one-way valves 222 and three-way valves 223. This main supply pipe passes through the hydrogen inlet 114 at the rear end of the housing 110 of the fuel cell module 100 and connects to a pressure sensor 170, which detects the hydrogen pressure. After passing through the pressure sensor 170, the hydrogen gas flows in three paths to the corresponding intake control valve 133a of each fuel cell stack 130, and then flows through pipelines into each fuel cell stack 130 to generate electricity. Each fuel cell stack 130 outputs current while consuming hydrogen gas, and the current is output through the positive and negative lines of the current output port of each fuel cell stack 130. Each fuel cell stack 130's positive terminal wire is connected to a corresponding current sensor 132, and then to three corresponding relays 134. The relays 134 are then connected to corresponding DC boost converters 160. The three DC boost converters 160 are connected in parallel, with the highest DC boost converter 160 outputting three paths (each path has two wires, one positive and one negative). The first path supplies power to external electrical equipment through the current output reserved hole 112. The second path connects to the lithium battery. The third path connects to the DC step-down converter 180, which supplies power to the control motherboard 150, solenoid valves 133, and other internal electrical devices during normal operation.

[0048] In addition, while the fuel cell stack 130 consumes hydrogen to generate electricity, each fuel cell pusher will output a small amount of unconsumed hydrogen and moisture generated during power generation from its outlet. Excess hydrogen and moisture will be output from the outlet of each fuel cell stack 130, and after being controlled by the corresponding exhaust control valve 133b, they will be combined into one path and then passed through the exhaust port 115 on the rear end face of the housing 110 via a pipeline, and then directly output to the hydrogen storage module 200. Upon encountering the hot air inside the hydrogen storage module 200, they will evaporate. The excess hydrogen and the evaporated water vapor will be discharged to the outside through the second hole 213 of the back plate 210 of the hydrogen storage module 200 along with the hot air in the hydrogen storage module 200.

[0049] The hydrogen power generation system provided by this utility model has a reasonable internal layout and small footprint, and can accommodate a large number of hydrogen storage devices 240. It is equipped with multiple fuel cell stacks 130 and can be adapted to large-scale machinery and equipment such as agricultural vehicles, providing them with power. It has a wide range of applications and strong adaptability. The design of the guide fan 140 can draw outside air into the air channel of the fuel cell stack 130 to supply oxygen for the reduction reaction, and can also conduct the hot air generated by the fuel cell stack 130 during operation to the hydrogen storage tank module 200, thereby improving the hydrogen release efficiency of the hydrogen storage device 240. The design of the heat conduction holes 224 on the partition plate 220 can ensure that the heat from the fuel cell stack 130 heats the multiple hydrogen storage devices 240 evenly, ensuring the waste heat utilization effect and guaranteeing the hydrogen transport efficiency of the hydrogen storage tank.

[0050] 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.
