[0002] All-Terrain Vehicles (ATVs), also known as off-road vehicles or four-wheeled off-road vehicles, are motor vehicles capable of traveling on various terrains. Currently, most ATVs are gasoline-powered, using an engine to convert the heat generated from burning gasoline into power.

[0003] A fuel cell system is a power generation device that directly converts chemical energy into electrical energy, offering advantages such as cleanliness, low carbon footprint, rapid start-up and shutdown, and zero noise. The fuel cell stack is the core of a hydrogen fuel cell system, responsible for the electrochemical reactions. A fuel cell stack consists of multiple individual cells stacked in series. Each individual cell includes a bipolar plate and a membrane electrode assembly (MEA), which are assembled using specific processes to form a proton exchange membrane fuel cell stack. The MEA, comprising a proton exchange membrane, catalyst, and gas diffusion layer, is the site of the electrochemical reactions and determines the stack's performance, lifespan, and cost. The bipolar plate is responsible for conducting electrons, distributing reactant gases, and removing generated water, while also serving as an isolation and connection component between cells. Using fuel cells in all-terrain vehicles can achieve zero emissions, low noise, high efficiency, and an excellent driving experience. Therefore, there is an urgent need for an all-terrain vehicle-mounted fuel cell stack installation structure to meet the requirements of combining all-terrain vehicles with fuel cells.

[0019] 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. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] This utility model provides an all-terrain vehicle-mounted fuel cell stack installation structure and an all-terrain vehicle, employing the following technical solution: An all-terrain vehicle-mounted fuel cell stack installation structure includes: a fuel cell stack body 13, which includes a membrane electrode 32 and a heat sink. The vehicle frame includes a fuel cell stack support and an upper crossbeam 19. There are at least two upper crossbeams 19. The bottom of the fuel cell stack body 13 is fixed to the fuel cell stack support by fasteners, and the top of the fuel cell stack body 13 is connected to the upper crossbeam 19.

[0022] The aforementioned fuel stacks include, but are not limited to, proton exchange membrane fuel stacks, alkaline fuel stacks, solid oxide fuel stacks, direct methanol fuel stacks, and hydrogen fuel stacks.

[0023] In one embodiment, the fuel cell stack support consists of two fuel cell stack support beams 24 arranged at the front of the vehicle frame, with the two fuel cell stack support beams 24 arranged along the width direction of the vehicle frame, and the fasteners are bolts. Alternatively, the fuel cell stack support can be a plate arranged along the width direction of the vehicle frame.

[0024] Furthermore, a support 21 is provided on the top of the fuel stack body 13, and a connector is provided on the support 21 for fixing the support 21 to the upper crossbeam 19. Specifically, the support 21 has mounting holes for mounting bolts. The mounting holes are strip-shaped holes to adjust for manufacturing and installation errors and ensure stable installation.

[0025] Furthermore, the all-terrain vehicle-mounted fuel cell stack installation structure includes a support tube assembly that is connected to the upper crossbeam 19 at one end and extends downward. The fuel cell stack support beam 24 is disposed at the support tube assembly, as shown in Figure 1. In one embodiment, the support tube assembly is an inclined support tube assembly, and each upper crossbeam 19 is provided with a set of inclined support tubes. The inclined support tube assembly includes a first inclined support tube 25 and a second inclined support tube 26. The other end of the first inclined support tube 25 extends to the lower crossbeam, and the other end of the second inclined support tube 26 is connected to the first support tube. The fuel cell stack support beam 24 is disposed between the first inclined support tube 25 and the second inclined support tube 26. Since the vehicle frame has upper crossbeams 19 on both the left and right sides, there are also two fuel cell stack support beams 24.

[0026] When plate components are used for the fuel cell stack support, one end of the support plate is fixed between the first inclined support tube 25 and the second inclined support tube 26 extending downward from the upper left crossbeam 19, and the other end is correspondingly fixed between the first inclined support tube 25 and the second inclined support tube 26 extending downward from the upper right crossbeam 19. This design ensures that the fixed positions of the fuel cell stack body 13 are evenly distributed vertically, resulting in uniform stress on the fuel cell stack body 13. The inclined support tube assembly and the upper crossbeam 19 form a triangular structure, which makes the installation of the vehicle-mounted fuel cell stack more stable.

[0027] Similarly, the support tube assembly can also use two vertical support tubes, with one end connected to the upper crossbeam and the other end connected to the lower crossbeam directly below the upper crossbeam 19. One end of the fuel cell stack support beam 24 or fuel cell stack support plate is positioned between the two vertical support tubes. By fixing the fuel cell stack support components and brackets 21 to the frame at multiple points, the load on the frame is more evenly distributed to cope with intense road vibration feedback.

[0028] The fuel stack body 13 is located at the front of the vehicle frame, which saves more space at the rear of the vehicle frame for the placement of the drive system and control devices.

[0029] Furthermore, the heat dissipation device includes a fan bracket 31, on which multiple cooling fans are mounted. A clamping device is provided between the membrane electrode 32 and the fan bracket 31, which is used to clamp the membrane electrode 32 and the fan bracket 31.

[0030] Furthermore, the clamping device includes a left fixing member and a right fixing member, the left fixing member and the right fixing member are connected to clamp the membrane electrode 32 and the fan bracket 31, and an adjusting member is provided between the left fixing member and the right fixing member for adjusting the distance between the left fixing member and the right fixing member.

[0031] Furthermore, two left fixing members 28 are spaced apart at one end of the fan bracket 31, and two right fixing members 29 are provided at the other end of the fan bracket 31, corresponding to the left fixing members 28.

[0032] Furthermore, the adjusting component is a screw 30, and the left fixing component 28 and the right fixing component 29 can be plate structures. Both are threadedly connected to the screw 30, and the distance between the left fixing component 28 and the right fixing component 29 is adjusted by the screw 30.

[0033] In one embodiment, the left fixing member includes two left fixing members 28 spaced apart along the width direction of the fan bracket 31. Similarly, the right fixing member has two right fixing members 29. The two left fixing members 28 and the two right fixing members 29 are respectively fixedly connected by corresponding bolts. The left fixing members 28 and the right fixing members 29 have lugs. The distance between the left fixing members and the right fixing members is adjusted by the screw 30 so that the lugs clamp and fix the membrane electrode 32 and the fan bracket 31. Considering the operating conditions of all-terrain vehicles, without affecting the fuel cell stack's air intake and exhaust, the fuel cell stack body is reinforced by adding clamping devices on both sides of the membrane electrode 32 and the fan bracket 31, thereby improving reliability. Specifically, multiple membrane electrodes 32 are fixed by fixing rods 33. In the embodiment shown in Figure 4, five fixing rods 33 are equidistantly arranged in the vertical direction. One of the fixing rods 33 is arranged horizontally parallel to the screw 30 away from the fan bracket, or it can be arranged horizontally parallel to both screws on both sides, so that the fixing rod 33, the screw 30, and the fan outlet are on the same horizontal plane. The fixing rod 33 will not further obstruct the fuel cell stack's exhaust.

[0034] On the other hand, this utility model also provides a fuel cell all-terrain vehicle, including the aforementioned all-terrain vehicle-mounted fuel cell stack mounting structure. Since the aforementioned all-terrain vehicle-mounted fuel cell stack mounting structure has the above-mentioned technical effects, the all-terrain vehicle with this all-terrain vehicle-mounted fuel cell stack mounting structure should also have corresponding technical effects, which will not be elaborated further here.
