Abstract
Description
Technical Field
[0001] This utility model relates to the field of fuel cell technology, and specifically to an aluminum fuel cell. Background Technology
[0002] Aluminum fuel cells are a novel battery technology. Their basic principle is based on the chemical reaction between aluminum fuel and oxygen. In an aluminum fuel cell, aluminum acts as the negative electrode (anode), where it is oxidized and releases electrons; oxygen acts as the positive electrode (cathode), where it gains electrons and is reduced. This flow of electrons generates an electric current, providing power to external devices. Meanwhile, the electrolyte plays a crucial role in transporting ions within the battery. It participates in the chemical reactions at the anode and cathode and ensures the uniform distribution of reactants, thereby maintaining stable battery operation.
[0003] CN203659993U discloses a fuel cell mounting device, comprising end plates adapted to both ends of a fuel cell stack and fasteners tightly connecting the end plates. The end plates are characterized by: an outer end plate, a pressure buffer, and a pressure dispersion and equalization plate; the pressure buffer is an elastic component, vertically disposed between the outer end plate and the pressure dispersion and equalization plate; the fasteners are I-shaped sheet structures, installed on the side of the fuel cell stack, with both ends fixedly connected to the end plates at both ends of the fuel cell stack. This invention addresses the problem of uneven internal stress and excessive local pressure caused by machining errors in various components of the fuel cell stack, as well as significant dimensional differences around the stack, through internal pressure regulation. It reduces the requirements for machining tolerances of internal components, effectively lowering machining costs and improving production efficiency.
[0004] While the existing technology CN203659993U has many advantages in use, it still has the following problems: its adaptability to battery stacks is not perfect. When the battery stack changes between high and low temperatures, its internal components will experience thermal expansion and contraction, resulting in the stacked components expanding and contracting, which affects the overall size of the battery. Traditional fixing methods cannot adapt to this. Utility Model Content
[0005] In view of the problems in the prior art, this utility model provides an aluminum fuel cell.
[0006] The technical solution adopted by this utility model to solve its technical problem is an aluminum fuel cell, including a first clamping plate, a second clamping plate, a storage groove and a limiting ring. The second clamping plate is provided on one outer wall of the first clamping plate. A support column distributed in a rectangular array is provided between the first clamping plate and the second clamping plate. A storage groove distributed in a rectangular array is opened on the outer wall of the second clamping plate. A fixing seat is placed inside the storage groove. A fitting groove is opened on one outer wall of the fixing seat. A screw hole is opened inside the fixing seat. A limiting plate is welded to one outer wall of the fixing seat. A limiting ring is provided on the inner wall of the storage groove opposite to the fixing seat.
[0007] By adopting the above technical solution, the first clamping plate and the second clamping plate are connected by the support column, which enhances the overall stability and durability. The first clamping plate and the second clamping plate provide the placement space for the fuel cell stack body through the support column, and the first clamping plate and the second clamping plate clamp and fix the fuel cell stack body. The support column further restricts the fuel cell stack body, ensuring that the use position of the fuel cell stack body is stable. The storage slot stores the fixing seat, ensuring that the first clamping plate and the second clamping plate have a telescopic space after clamping and fixing the fuel cell stack body, allowing the distance between the first clamping plate and the second clamping plate to be adjusted. This ensures that the overall dimensional changes caused by thermal expansion and contraction of the fuel cell stack body can be adapted to by the first clamping plate and the second clamping plate, and ensures that the clamping of the fuel cell stack body is stable, which can improve the service life of the fuel cell stack body. The limiting plate and the limiting ring can limit the movement distance of the fixing seat, thereby limiting the movement distance of the first clamping plate.
[0008] Specifically, a fuel cell stack body is provided between the first clamping plate and the second clamping plate, and quick-connect connectors are inserted and installed on both outer walls of the first clamping plate and the second clamping plate, and the quick-connect connectors are connected to the inside of the fuel cell stack body.
[0009] By adopting the above technical solution, the fuel cell stack is the core component of the aluminum fuel cell, responsible for generating electrical energy. The introduction of quick-connect connectors simplifies the connection process between the fuel cell stack and external equipment, improving the convenience and efficiency of the connection. At the same time, the quick-connect connectors are connected to the inside of the fuel cell stack, ensuring the stable transmission of oxygen and electrolyte inside the fuel cell stack.
[0010] Specifically, fasteners are welded to the outer walls of both sides of the first and second clamping plates.
[0011] By adopting the above technical solution, the fastener provides additional support and fixing points for the first and second clamping plates, which helps to further consolidate the overall structure of the battery, and the external fixing points can adapt to the movement of the first clamping plate.
[0012] Specifically, a fitting block is welded to the outer wall of one end of the support column, and the fitting block is located inside the fitting groove.
[0013] By adopting the above technical solution, the design of the interlocking block and the interlocking groove realizes a firm connection between the support column and the fixed seat. This connection method not only improves the stability of the structure, but also simplifies the installation process and reduces the assembly difficulty. When the support column moves with the first clamping plate, it can cooperate with the fixed seat to limit the size of the fuel cell stack body.
[0014] Specifically, the first clamping plate is movably installed with bolts arranged in a rectangular array, one side of which is threaded into a screw hole, and the bolt is located inside the support column.
[0015] By adopting the above technical solution, the first clamping plate, the second clamping plate, and the fixing seat are connected and fixed. The adjustability of the bolts makes the structure more flexible and can be finely adjusted as needed to ensure that all components are tightly connected together. The workers lay the fuel cell stack body inside the first clamping plate and the second clamping plate, and make the bolts pass through the first clamping plate and the support column, and finally engage inside the bolt holes, so that the first clamping plate and the second clamping plate can provide clamping force to the fuel cell stack body, thereby achieving clamping and fixing of the fuel cell stack body.
[0016] Specifically, springs are provided on both outer walls of the fixed base, and two springs are distributed on both sides of the limiting plate. The limiting plate is elastically connected to the inner wall of the storage groove and the outer wall of the limiting ring through the springs.
[0017] By adopting the above technical solution, the spring supports the limiting plate, ensuring that the limiting plate is stable in the position inside the storage slot, and ensuring the clamping force and clamping stability of the first and second clamping plates on the fuel cell stack body. When the first and second clamping plates are relatively displaced, the spring force can assist the first and second clamping plates to reset, so that the distance between the first and second clamping plates can adapt to the changes in the overall size of the fuel cell stack body caused by thermal expansion and contraction.
[0018] Specifically, the outer wall of the limiting ring is welded with a circular array of support members, and screws are provided inside the support members. The support members are connected to the outer wall of the second clamping plate by the screws.
[0019] By adopting the above technical solution, the support component provides additional support points for the limiting ring, enhancing the connection strength between the limiting ring and the second clamping plate. The screws ensure that the support component is firmly fixed to the second clamping plate. This design helps prevent the limiting ring from loosening or falling off during long-term use, thereby improving the stability and safety of the entire structure.
[0020] The beneficial effects of this utility model are:
[0021] (1) The aluminum fuel cell described in this utility model ensures that the first clamping plate and the second clamping plate have a telescopic space after clamping and fixing the fuel cell body, so that the distance between the first clamping plate and the second clamping plate can be adjusted, so that the overall size change caused by thermal expansion and contraction of the fuel cell body can be adapted by the first clamping plate and the second clamping plate, and ensures that the fuel cell body is clamped firmly, thereby improving the service life of the fuel cell body.
[0022] (2) The aluminum fuel cell described in this utility model has a design of interlocking blocks and interlocking slots that achieves a firm connection between the support column and the fixed seat. This connection method not only improves the stability of the structure, but also simplifies the installation process and reduces the assembly difficulty.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0030] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the aluminum fuel cell of this utility model includes a first clamping plate 1, a second clamping plate 11, a storage groove 2, and a limiting ring 3. The second clamping plate 11 is provided on one outer wall of the first clamping plate 1. A support column 13 distributed in a rectangular array is provided between the first clamping plate 1 and the second clamping plate 11. A storage groove 2 distributed in a rectangular array is provided on the outer wall of the second clamping plate 11. A fixing seat 21 is placed inside the storage groove 2. A fitting groove 23 is provided on one outer wall of the fixing seat 21. A screw hole 22 is provided inside the fixing seat 21. A limiting plate 24 is welded to one outer wall of the fixing seat 21. A limiting ring 3 is provided on the inner wall of the storage groove 2 opposite to the fixing seat 21.
[0031] In use, the first clamping plate 1 and the second clamping plate 11 are connected by the support column 13, which enhances the overall stability and durability. The first clamping plate 1 and the second clamping plate 11 provide the placement space for the fuel cell stack body 12 through the support column 13, and the first clamping plate 1 and the second clamping plate 11 clamp and fix the fuel cell stack body 12. The support column 13 further restricts the fuel cell stack body 12 to ensure that the position of the fuel cell stack body 12 is stable. The storage slot 2 stores the fixing seat 21, ensuring that the first clamping plate 1 and the second clamping plate 11 have a telescopic space after clamping and fixing the fuel cell stack body 12, so that the distance between the first clamping plate 1 and the second clamping plate 11 can be adjusted. This ensures that the overall size change of the fuel cell stack body 12 caused by thermal expansion and contraction can be adapted by the first clamping plate 1 and the second clamping plate 11, and ensures that the clamping of the fuel cell stack body 12 is stable, which can improve the service life of the fuel cell stack body 12. The limiting plate 24 and the limiting ring 3 can limit the movement distance of the fixing seat 21, thereby limiting the movement distance of the first clamping plate.
[0032] To generate electricity, for example, such as Figure 1 As shown, a fuel cell stack body 12 is disposed between the first clamping plate 1 and the second clamping plate 11. Quick-connect connectors 14 are inserted and installed on both outer walls of the first clamping plate 1 and the second clamping plate 11, and the quick-connect connectors 14 are connected to the inside of the fuel cell stack body 12.
[0033] In use, the stack body 12 is the core component of the aluminum fuel cell, responsible for generating electrical energy. The introduction of the quick-connect connector 14 simplifies the connection process between the stack body 12 and external equipment, improving the convenience and efficiency of the connection. At the same time, the quick-connect connector 14 is connected to the inside of the stack body 12, ensuring the stable transmission of oxygen and electrolyte inside the stack body 12.
[0034] To fix the usage location, for example, such as Figure 1 As shown, fasteners 15 are welded to the outer walls of both sides of the first clamping plate 1 and the second clamping plate 11.
[0035] In use, the fastener 15 provides additional support and fixing points for the first clamping plate 1 and the second clamping plate 11, which helps to further consolidate the overall structure of the battery, and the external fixing points can accommodate the movement of the first clamping plate 1.
[0036] For a stable connection, for example, such as Figure 3 As shown, a fitting block 17 is welded to the outer wall of one end of the support column 13, and the fitting block 17 is located inside the fitting groove 23.
[0037] In use, the design of the interlocking block 17 and the interlocking groove 23 realizes a firm connection between the support column 13 and the fixed seat 21. This connection method not only improves the stability of the structure, but also simplifies the installation process and reduces the assembly difficulty. When the support column 13 moves with the first clamping plate 1, it can cooperate with the fixed seat 21 to limit the size of the fuel cell body 12.
[0038] For a secure connection, for example, such as Figure 2 As shown, a rectangular array of bolts 16 are movably installed inside the first clamping plate 1. One side of the bolt 16 is threaded into the screw hole 22, and the bolt 16 is located inside the support column 13.
[0039] In use, it serves to connect and fix the first clamping plate 1, the second clamping plate 11, and the fixing seat 21. The adjustability of the bolt 16 makes the structure more flexible and can be finely adjusted as needed to ensure that all components are tightly connected together. The operator lays the fuel cell stack body 12 inside the first clamping plate 1 and the second clamping plate 11, and makes the bolt 16 pass through the first clamping plate 1 and the support column 13, and finally engages inside the bolt hole 22, so that the first clamping plate 1 and the second clamping plate 11 can provide clamping force to the fuel cell stack body 12, thereby achieving clamping and fixing of the fuel cell stack body 12.
[0040] To maintain clamping force, for example, such as Figure 4 As shown, springs 25 are provided on both outer walls of the fixed base 21. The two springs 25 are distributed on both sides of the limiting plate 24. The limiting plate 24 is elastically connected to the inner wall of the storage groove 2 and the outer wall of the limiting ring 3 through the springs 25.
[0041] During use, the spring 25 supports the limiting plate 24 to ensure that the limiting plate 24 is stably positioned inside the storage slot 2, and to ensure the clamping force and clamping stability of the first clamping plate 1 and the second clamping plate 11 on the fuel cell body 12. When the first clamping plate 1 and the second clamping plate 11 are relatively displaced, the elastic force of the spring 25 can assist the first clamping plate 1 and the second clamping plate 11 to reset, so that the distance between the first clamping plate 1 and the second clamping plate 11 can adapt to the changes in the overall size of the fuel cell body 12 caused by thermal expansion and contraction.
[0042] To limit the distance of movement, for example, such as Figure 4As shown, the outer wall of the limiting ring 3 is welded with a circular array of support members 31, and screws 32 are provided inside the support members 31. The support members 31 are connected to the outer wall of the second clamping plate 11 through the screws 32.
[0043] During use, the support member 31 provides an additional support point for the limiting ring 3, enhancing the connection strength between the limiting ring 3 and the second clamping plate 11. The screw 32 ensures that the support member 31 is firmly fixed on the second clamping plate 11. This design helps prevent the limiting ring 3 from loosening or falling off during long-term use, thereby improving the stability and safety of the entire structure.
[0044] In use, the battery stack body 12 is placed between the first clamping plate 1 and the second clamping plate 11 to ensure that the battery stack body 12 is connected to the quick connector 14. Springs 25 are installed on the outer walls of both sides of the fixed base 21. One end of the spring 25 is connected to the limiting plate 24 of the fixed base 21, and the other end is connected to the inner wall of the storage groove 2. The position of the limiting ring 3 is fixed by screws 32, thereby limiting the displacement distance of the fixed base 21.
[0045] Place the support column 13 between the first clamping plate 1 and the second clamping plate 11, and insert the bolt 16 through the first clamping plate 1 and the support column 13, and finally thread it into the screw hole 22 of the fixing seat 21. Adjust the tightness of the bolt 16 to ensure that the first clamping plate 1 and the second clamping plate 11 can provide appropriate clamping force to the fuel cell stack body 12.
