Description

Technical Field

[0001] This application relates to the field of fuel cell technology, and more particularly to a hydrogen fuel cell and a two-wheeled vehicle. Background Technology

[0002] Hydrogen fuel cells are increasingly being widely used in long-distance heavy-duty highways, rail transit, ships, airplanes, independent energy sources, combined heat and power, and light vehicles (such as two-wheeled vehicles and three-wheeled vehicles) due to their advantages such as high efficiency (theoretical efficiency can reach more than 80%), zero emissions and no pollution (the only product is water), good low temperature adaptability (can be used normally at -30℃), and fast energy replenishment speed.

[0003] In two-wheeled vehicle applications, the power system of a hydrogen fuel cell two-wheeler typically includes a fuel cell stack module, a hydrogen tank (hydrogen storage system), a battery (auxiliary power supply or main battery), and related control systems and pipelines. The fuel cell stack module, hydrogen tank, and battery are often arranged separately. For example, the hydrogen tank is usually installed in a specific location on the vehicle (such as under the frame or inside the seat), the fuel cell stack module is installed in other parts of the vehicle (such as in the middle or bottom of the frame), and the battery may be located at the front or rear of the vehicle. However, this separate arrangement requires long pipelines connecting the hydrogen tank and the fuel cell stack module, and between the fuel cell stack module and the battery. This increases pressure loss during hydrogen transportation, reduces hydrogen supply efficiency, and thus affects the power generation efficiency of the fuel cell stack module. Furthermore, due to the dispersed arrangement of components and the complexity of the pipelines, maintenance and repair require the disassembly of many parts, increasing the difficulty and cost of maintenance. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides a hydrogen fuel cell system and a two-wheeled vehicle.

[0005] In a first aspect, this application provides a hydrogen fuel cell, including a housing with a receiving cavity and a functional component installed within the receiving cavity, wherein an air inlet communicating with the receiving cavity is provided on one side wall of the housing; wherein the functional component includes:

[0006] The fuel cell stack module contains a hydrogen chamber and an air chamber.

[0007] A battery module is located on one side of the fuel cell stack module and is electrically connected to the fuel cell stack module;

[0008] A hydrogen storage cylinder is arranged side by side with the battery module on one side of the fuel cell stack module. A cylinder valve is installed at the cylinder opening, and the outlet of the cylinder valve is connected to the hydrogen chamber of the fuel cell stack module through a gas supply pipe.

[0009] An air pump is fixed to the outer surface of the fuel cell stack module. The air outlet of the air pump is connected to the air chamber of the fuel cell stack module through an air pipe. The air inlet of the air pump faces the air inlet hole and is used to introduce external air into the air chamber of the fuel cell stack module through the air pipe.

[0010] In one embodiment, the device further includes a first fixing component, which includes at least two clamps stacked in the receiving cavity along a first direction. The clamps are located outside the battery module, and at least a portion of the outer peripheral surface of the clamps is fixedly connected to the inner wall of the housing. The hydrogen storage bottle passes through the clamping space formed by the clamps along the first direction to fix the hydrogen storage bottle in the receiving cavity.

[0011] In one embodiment, the clamp includes a hoop, a hook, and a buckle. The hoop forms an open clamping space around its center, and both ends of the hoop are bent to form symmetrical bends. The hook and the buckle are respectively disposed on the two bends, and the buckle cooperates with the hook.

[0012] In one embodiment, the clamp is bent in the direction away from the hydrogen storage cylinder to form a mounting part, and a mounting block is fixed at the intersection of two adjacent inner sidewalls of the shell, and the mounting block is detachably connected to the mounting part.

[0013] In one embodiment, a second fixing component is further included, comprising two fixing brackets stacked in the receiving cavity along the first direction. The fixing brackets are disposed between two adjacent inner sidewalls of the housing and located on the opposite side of the hydrogen storage cylinder. The two fixing brackets and the two adjacent inner sidewalls of the housing together define a mounting cavity for mounting the battery module. When the battery module is installed in the mounting cavity, the inner side of the fixing bracket is in close contact with the outer surface of the battery module.

[0014] In one embodiment, the fixing frame includes two fixing bars, which are vertically connected to form an L-shape, and each of the two fixing bars has a connecting portion bent at one end away from the other for connecting to the inner sidewall of the housing.

[0015] In one embodiment, a third fixing component is further included, the third fixing component including a first mounting bracket and a second mounting bracket, the first mounting bracket being fixed to the inner sidewall of the housing facing the outer surface of the fuel cell module, and the second mounting bracket being fixed to the outer surface of the fuel cell module for cooperating with the first mounting bracket.

[0016] In one embodiment, the functional device further includes a concentration sensor located directly above the bottle neck valve in the first direction.

[0017] In one embodiment, the outer surface of the fuel cell module is provided with a heat sink, and a cooling fan is provided on the heat dissipation surface of the heat sink.

[0018] Secondly, this application also provides a two-wheeled vehicle, including the hydrogen fuel cell system described in the first aspect.

[0019] The technical solutions provided in this application have the following advantages compared with the prior art:

[0020] By integrating the fuel cell stack, battery module, hydrogen storage tank, and air pump into the housing, a centralized layout is created, resulting in a more compact structure. This avoids the spatial clutter caused by dispersed arrangements and also shortens the length of air pipes and gas delivery pipes. During maintenance and repair, staff do not need to disassemble multiple scattered components on the vehicle. They only need to operate on the functional components and simplified pipelines centrally located within the housing, which allows for quick location of faults. This reduces the number of components to be disassembled and installed, as well as the number of operating steps, significantly reducing maintenance difficulty. Attached Figure Description

[0035] The technical terms used in the embodiments of this application are explained and described below.

[0036] Functional components are a collection of components that constitute the core unit of a hydrogen fuel cell system. In addition to the stack module 70, battery module 30, hydrogen storage tank 20 and air pump 80 in the following embodiments, they also include existing components required to convert hydrogen energy into electrical energy, such as DC / DC converters and vehicle controllers (ECUs). The components and specific connections included in the fuel cell system are common knowledge to those skilled in the art, and will not be described in detail here.

[0037] The first direction X is defined for ease of describing the positional relationship between components; specifically, in this embodiment, the housing is used as the reference. Here, the first direction X refers to the height direction of the housing (referring to...). Figure 1 (in the X direction).

[0038] Figure 1 This is a schematic diagram of the structure of a hydrogen fuel cell system according to this application; Figure 2 This is a top view schematic diagram of a hydrogen fuel cell system according to this application; Figure 3 This is a schematic diagram of the structure of a hydrogen fuel cell system after removing the casing 10 according to this application; Figure 4 This is a schematic diagram of the hydrogen fuel cell system of this application from another perspective after removing the casing 10. Please refer to... Figures 1 to 4 This application provides a two-wheeled vehicle, which includes a frame and a hydrogen fuel cell system mounted on the frame. The hydrogen fuel cell system can convert hydrogen energy into electrical energy to drive the frame. Furthermore, since the hydrogen fuel cell system only emits pure water during the conversion to electricity, it produces no pollution and is a clean energy source, aligning with the current low-carbon development trend of new energy transportation.

[0039] Specifically, the hydrogen fuel cell system includes a housing with a receiving cavity 10a and functional components installed in the receiving cavity 10a, and an air inlet is provided on one side wall of the housing to communicate with the receiving cavity 10a. The functional components include a fuel cell stack module 70, a battery module 30, a hydrogen storage tank 20, and an air pump 80. The fuel cell stack module 70 has a hydrogen chamber and an air chamber inside. The battery module 30 is located on one side of the fuel cell stack module 70 and is electrically connected to the fuel cell stack module 70. The hydrogen storage tank 20 is arranged side by side with the battery module 30 on one side of the fuel cell stack module 70. A valve 130 is installed at the mouth of the hydrogen storage tank 20. The outlet of the valve 130 is connected to the hydrogen chamber of the fuel cell stack module 70 through a gas supply pipe. The air pump 80 is fixed on the outer surface of the fuel cell stack module 70. The outlet of the air pump 80 is connected to the air chamber of the fuel cell stack module 70 through an air pipe 120. The air inlet of the air pump 80 faces the air inlet hole and is used to introduce external air into the air chamber of the fuel cell stack module 70 through the air pipe 120.

[0040] In practical applications, when power generation is required, the cylinder valve 130 opens according to the control system command, allowing high-pressure hydrogen gas in the hydrogen storage cylinder 20 to flow out through the outlet of the cylinder valve 130 and be directly input into the hydrogen chamber of the fuel cell stack module 70 through the gas delivery pipe. Simultaneously, the air pump 80 operates, drawing in external air through the air inlet. After pressurization, the air is directly input into the air chamber of the fuel cell stack module 70 via the air pipe 120. The hydrogen gas entering the hydrogen chamber undergoes an oxidation reaction under the action of a catalyst (such as a platinum catalyst), decomposing the hydrogen gas into positively charged protons and negatively charged electrons. The protons then move through the electrolyte membrane inside the fuel cell stack module 70 towards the air chamber, while the oxygen entering the air chamber becomes an electron acceptor under the action of the catalyst, combining with the protons migrating from the electrolyte membrane to undergo a reduction reaction to produce water. Since the decomposed electrons cannot pass through the electrolyte membrane, an electric current is generated to provide power for driving the vehicle.

[0041] In addition, the battery module 30 and the fuel cell stack module 70 can be electrically connected via cables, so that when the fuel cell stack module 70 is in the initial stage of startup or when the vehicle is under high load (the instantaneous power generation of the fuel cell stack cannot meet the demand), the battery module 30 can directly supplement the load with power to ensure the normal operation of the two-wheeled vehicle. When the power generation of the fuel cell stack module 70 exceeds the load demand (such as when the vehicle is traveling at low speed), the excess electrical energy can be stored in the battery module 30 through the electrical connection line to avoid energy waste.

[0042] The air pump 80 is positioned so that the air inlet faces the air outlet to directly and smoothly introduce external air, avoiding insufficient air intake caused by a tortuous air intake path. This ensures a continuous supply of air required for the oxidation reaction of the fuel cell module 70, and, in conjunction with the optimization of the hydrogen supply, maintains the high-efficiency power generation state of the fuel cell module 70.

[0043] In other words, the hydrogen fuel cell system of this application integrates the stack module 70, battery module 30, hydrogen storage tank 20 and air pump 80 into the housing cavity 10a, forming a centralized layout. The structure is more compact, avoiding the spatial clutter caused by dispersed arrangement. At the same time, it can shorten the length of air pipe 120 and gas transmission pipe. During maintenance and repair, the staff does not need to disassemble multiple dispersed parts on the vehicle. They only need to operate on the functional parts and simplified pipelines centrally arranged in the housing. The fault location can be quickly located, reducing the number of parts to be disassembled and installed and the number of operation steps, which significantly reduces the maintenance difficulty.

[0044] In practical applications, two-wheeled vehicles may experience bumps, turns, and sudden braking during operation. If the hydrogen storage cylinder 20 within the receiving cavity 10a is not secured, it will shake violently, continuously impacting components such as the fuel cell module 70 and battery module 30. This could lead to cylinder deformation, weld cracking, or even direct rupture, causing a sudden leak of high-pressure hydrogen. Therefore, in one embodiment, a first fixing component 40 is included. The first fixing component 40 includes at least two clamps 41 stacked along a first direction X within the receiving cavity 10a. The clamps 41 are located outside the battery module 30, and at least a portion of their outer peripheral surfaces are fixedly connected to the inner wall of the housing. The hydrogen storage cylinder 20 passes through the clamping space A formed by the clamps 41 along the first direction X, thereby securing the hydrogen storage cylinder 20 within the receiving cavity 10a.

[0045] In other words, by stacking two clamps 41 along the first direction X, and passing the hydrogen storage cylinder 20 through the clamping space A formed by the clamps 41 along the first direction X, and then fixing the outer circumferential surface of the clamps 41 to the inner wall of the housing, a ring clamp is formed from different axial positions of the hydrogen storage cylinder 20. This effectively restricts the displacement of the hydrogen storage cylinder 20, ensuring that the hydrogen storage cylinder 20 will not shake violently or slide under conditions of bumps, sudden braking, and turn signal activation during two-wheeled vehicle operation, thus preventing the cylinder from impacting the battery module 30, the fuel cell stack module 70, or the inner wall of the housing. In addition, the clamps 41 are arranged on the outside of the battery module 30, which neither occupies the installation space of the battery module 30 nor changes the side-by-side integration relationship of the hydrogen storage cylinder 20 and the fuel cell stack module 70, avoiding congestion of the housing cavity 10a due to the addition of a fixing structure.

[0046] Figure 5 This is a schematic diagram of the structure of the clamp 41 in a hydrogen fuel cell system according to this application. (Refer to...) Figure 5The clamp 41 includes a hoop 411, a hook 413, and a buckle 412. The hoop 411 forms a clamping space A with an opening around its center, and the two ends of the hoop 411 are bent to form symmetrical bent portions 411b. The hook 413 and the buckle 412 are respectively provided on the two bent portions 411b, and the buckle 412 cooperates with the hook 413. In other words, when it is necessary to secure the hydrogen storage cylinder 20, firstly, disengage the latch 412 from the hook 413 so that the hydrogen storage cylinder 20 passes through the clamping space A along the first direction X. Then, insert the latch 412 into the hook 413 so that the clamp 41 applies a holding force to the hydrogen storage cylinder 20, thereby securing the hydrogen storage cylinder 20 and preventing it from shaking. When it is necessary to replace the hydrogen storage cylinder 20, simply disengage the latch 412 from the hook 413 so that the clamp 41 releases its grip on the hydrogen storage cylinder 20. At this time, simply remove the hydrogen storage cylinder 20 from the receiving cavity 10a along the first direction X. Compared with the traditional bolt connection method, the hydrogen storage cylinder 20 can be quickly disassembled and assembled without the use of additional tools, which can significantly reduce the overall maintenance time.

[0047] Furthermore, a mounting portion 411a is formed by bending the clamp 41 away from the hydrogen storage tank 20. A mounting block 100 is fixed at the intersection of two adjacent inner sidewalls of the housing, and the mounting block 100 is detachably connected to the mounting portion 411a. In this way, the mounting portion 411a and the mounting block 100 can be connected to each other, and then fasteners (such as bolts) can be passed through the through holes of the mounting portion 411a and the mounting block 100 in sequence to detachably connect the clamp 41 to the inner sidewall of the housing 10. If the clamp 41 rusts or deforms due to long-term use, it can be disassembled and replaced separately without replacing the entire housing or the mounting block 100, which significantly reduces maintenance costs. At the same time, the mounting block 100 can be reused for a long time, and only clamps 41 with the same specification mounting portion 411a need to be matched, which improves the versatility of the components.

[0048] In addition, the intersection of adjacent inner walls of the housing is usually an unused space (not the core installation area of ​​the stack module 70 and battery module 30). Placing the mounting block 100 here can avoid the dense layout of functional components inside the housing, and there is no need to reserve extra space for the mounting block 100. This maintains the compact integrated layout of the housing cavity 10a and does not disrupt the original component arrangement logic.

[0049] In one embodiment, a second fixing component 50 is further included. The second fixing component 50 includes two fixing brackets 51 stacked in the receiving cavity 10a along a first direction X. The fixing brackets 51 are located between two adjacent inner sidewalls of the housing and on the opposite side of the hydrogen storage cylinder 20. The two fixing brackets 51 and the two adjacent inner sidewalls of the housing together define a mounting cavity for mounting the battery module 30. When the battery module 30 is installed in the mounting cavity, the inner side of the fixing bracket 51 is in close contact with the outer surface of the battery module 30.

[0050] In other words, the two adjacent inner sidewalls of the housing and the fixing frame 51 together form an installation cavity, so that after the battery module 30 is inserted, the inner sidewalls of the housing and the inner side of the fixing frame 51 will completely surround the battery module 30. Therefore, the bumps and turns during the two-wheeled vehicle's operation will be blocked by the inner sidewalls of the housing and the fixing frame 51, preventing the battery module 30 from moving or rotating radially, thus avoiding collisions of the battery casing and displacement of the battery cells caused by shaking. If the battery module 30 needs to be repaired or replaced, only the fixing frame 51 needs to be removed, so that the fixing frame 51 is freed from restricting the battery module 30, and the battery module 30 can be quickly removed from the receiving cavity 10a without disassembling other components such as the hydrogen storage tank 20 and the stack module 70, and without damaging the housing structure, thus reducing maintenance costs.

[0051] Figure 6 This is a schematic diagram of the structure of the mounting bracket 51 in a hydrogen fuel cell system according to this application. (Refer to...) Figure 6 The mounting bracket 51 includes two fixing strips 511, which are vertically connected to form an L-shape. Each fixing strip 511 has a connecting portion 511a bent at its far end for connection to the inner sidewall of the housing. Thus, the connecting portions 511a formed by the bending of the two fixing strips 511 are fixedly connected to two adjacent inner sidewalls of the housing, defining a mounting cavity for the battery module 30. This allows for the definition of multiple sides of the battery module 30, preventing it from shifting out of the gap between the fixing strips 511 and the sidewalls, and providing a stable spatial foundation for battery fixation.

[0052] In one embodiment, a third fixing component 110 is also included. The third fixing component 110 includes a first mounting bracket 112 and a second mounting bracket 111. The first mounting bracket 112 is fixed to the inner sidewall of the housing facing the outer surface of the fuel cell stack module 70, and the second mounting bracket 111 is fixed to the outer surface of the fuel cell stack module 70 for cooperating with the first mounting bracket 112. That is, when the fuel cell stack module 70 is installed in the receiving cavity 10a, the second mounting bracket 111 and the first mounting bracket 112 are aligned, and then fasteners (such as bolts) are used to pass through them to fix the fuel cell stack module 70, ensuring that the fuel cell stack module 70 remains in a fixed position under various dynamic operating conditions of the two-wheeled vehicle, protecting its internal precision structure from mechanical impact damage.

[0053] In one embodiment, the functional device also includes a concentration sensor 60, which is located directly above the bottle valve 130 in the first direction X. Thus, when hydrogen leaks in the hydrogen storage tank 20, the concentration sensor 60 located directly above the bottle valve 130 can detect the hydrogen leak in time and issue an early warning, thereby controlling the bottle valve 130 to close automatically, which improves safety.

[0054] In one embodiment, a heat sink 90 is provided on the outer surface of the fuel cell module 70, and a cooling fan 140 is provided on the heat dissipation surface of the heat sink 90. ​​That is, by using the heat sink 90 to be in close contact with the outer surface of the fuel cell module 70, the heat conducted by the fuel cell module 70 can be quickly absorbed through surface contact, thereby greatly increasing the contact area with the air and allowing the heat to be quickly diffused into the surrounding air. At the same time, the cooling fan 140 accelerates the rapid dissipation of heat and prevents the temperature from rising continuously.

[0055] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
