Description

Technical Field

[0001] This utility model relates to the field of battery stack fabrication technology, and in particular to a microtubular solid oxide fuel cell stack fabrication device based on 3D printing technology. Background Technology

[0002] To improve the fabrication efficiency, energy conversion efficiency, and operational life of direct carbon solid oxide fuel cell (DC-SOFC) stacks, it is proposed to use 3D printing technology to directly fabricate microtubular solid oxide fuel cell stacks. The stacks will be fabricated using 3D-printed anode modules to study various operational mechanisms. The anode modules produced using 3D printing technology can have relatively complex internal gas channel structures, eliminating the need for local assembly processes. This can save on the fabrication and assembly of individual cells, reduce fuel cell fabrication costs, and improve fabrication accuracy and efficiency.

[0003] An anode module is 3D printed using a resin-ceramic composite slurry. YSZ and LSM are used as the electrolyte and cathode materials, respectively. Electrolyte and cathode emulsions are prepared and impregnated, and the resulting fuel cell stack is obtained after high-temperature sintering. During the impregnation process, the electrolyte and cathode emulsion need to be rapidly dispersed on the anode module, minimizing any uncovered areas. Otherwise, the impregnation process will be slow or the impregnation effect will be unsatisfactory, affecting product quality. The problem of slow anode module impregnation in existing technologies needs to be addressed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a microtubular solid oxide fuel cell stack preparation device based on 3D printing technology to address the above-mentioned technical deficiencies. This device solves the problem of slow anode module impregnation process in the prior art.

[0005] The technical solution adopted in this utility model is: to provide a microtubular solid oxide fuel cell stack fabrication device based on 3D printing technology, for impregnating 3D printed anode modules, including:

[0006] The base has a vertically arranged limiting plate and a horizontally arranged top plate. The limiting plate has a limiting hole, and the top plate is located above the limiting plate.

[0007] The support plate has a rotating shaft at the bottom, which is rotatably mounted on the base. One side of the rotating shaft has a slot arranged along the axial direction. The upper part of the support plate has a socket, into which the anode module is inserted. The support plate is located next to the limiting plate.

[0008] The control lever is rotatably disposed relative to the base and has a transmission part. The transmission part is slidably disposed in the slot for driving the support plate to rotate. The control lever is movable relative to the support plate.

[0009] A positioning rod is disposed on the control rod and located next to the transmission part. The positioning rod is positioned opposite to the limiting hole and is inserted into it. When the control rod moves away from the support plate, the transmission part is located in the slot, and the positioning rod is withdrawn from the limiting hole. The top plate is located above the positioning rod.

[0010] To further optimize this technical solution, there are two positioning rods, which are respectively located on both sides of the transmission part; the limiting plate has two limiting holes, and the positions of the limiting holes and the positioning rods correspond one-to-one. When the positioning rod rotates with the control rod, the positioning rod moves upward and abuts against the top plate.

[0011] Further optimization of this technical solution also includes:

[0012] A compression spring, with one end acting on the control rod and the other end acting on the base, is used to provide a force for the positioning rod to move closer to the limiting plate.

[0013] To further optimize this technical solution, the control lever has a handle on its end side located outside the base, and the control lever is rotatably mounted on the base.

[0014] Further optimization of this technical solution also includes:

[0015] The mounting bracket is mounted on the base and located next to the support plate;

[0016] A support frame is rotatably mounted on the upper end of the mounting bracket and located above the anode module. A syringe is slidably mounted on the support frame, with the syringe outlet opposite to the anode module.

[0017] To further optimize this technical solution, the support frame has a through groove, and a syringe is slidably disposed within the through groove.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. The support plate can drive the anode module to shake, which accelerates the flow and rapid dispersion of electrolyte and cathode emulsion. At the same time, the shaking helps to more comprehensively cover the area on the anode module that needs to be impregnated, thus accelerating impregnation and improving the impregnation effect.

[0020] 2. When the positioning rod is inserted into the limiting hole, the support plate is in a horizontal positioning state. After the positioning rod is disengaged from the limiting hole, the control rod can drive the support plate to swing. During the swing, the positioning rod can hit the top plate to form a knocking vibration, which is transmitted to the anode module. This is beneficial for the rapid dispersion and more comprehensive coverage of the electrolyte and cathode emulsion, reducing the area of ​​immersion omission. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figure 1-5 As shown, a microtubular solid oxide fuel cell stack fabrication device based on 3D printing technology is used for impregnating anode modules 9 manufactured by 3D printing. The device includes: a base 1 with a vertically arranged limiting plate 101 and a horizontally arranged top plate 102. The limiting plate 101 has a limiting hole 1011, and the top plate 102 is located above the limiting plate 101; a support plate 2 with a rotating shaft 201 at its lower part, the rotating shaft 201 being rotatably mounted on the base 1. One side of the rotating shaft 201 has a slot 2011 arranged along the axial direction. The upper part of the support plate 2 has a socket 202, into which the anode module 9 is inserted. Inside the support plate 2, the support plate 2 is located next to the limiting plate 101; the control rod 3 is rotatably arranged relative to the base 1 and has a transmission part 301. The transmission part 301 is slidably arranged in the slot 2011 and is used to drive the support plate 2 to rotate. The control rod 3 is moved relative to the support plate 2; the positioning rod 4 is arranged on the control rod 3 and is located next to the transmission part 301. The positioning rod 4 is opposite to the limiting hole 1011 and is inserted into it. When the control rod 3 moves away from the support plate 2, the transmission part 301 is located in the slot 2011 and the positioning rod 4 is withdrawn from the limiting hole 1011. The top plate 102 is located above the positioning rod 4.

[0032] In initial use, the positioning rod 4 is inserted into the limiting hole 1011, the support plate 2 is in a horizontal state, and the anode module 9 is inserted and positioned on the socket 202. Electrolyte emulsion and cathode emulsion, or other impregnation additives, can be added sequentially to the pipe area on the anode module 9 using a feeding device such as a syringe 8. Pulling the control rod 3 outward a suitable distance allows the positioning rod 4 to exit from the limiting hole 1011, while the transmission part 301 remains in the slot 2011. Reciprocating rotation of the control rod 3 causes the support plate 2 to swing. When the support plate 2 swings back and forth within a small angle range, the anode module 9 can accelerate the flow and coverage of the additives through shaking, which helps to reduce missed areas. At the same time, when the control rod 3 rotates, the positioning rod 4 swings upward and can collide with the top plate 102, enhancing the flow and coverage of the additives through vibration. The base 1 includes a top plate 102 and a bottom plate. The positioning rod 4 can collide with the top plate 102 and the bottom plate respectively when swinging up and down, and at the same time form the corner limit of the control rod 3, so that the anode module 9 does not need to shake at a large angle.

[0033] The anode module 9 can be detachably connected to the socket 202 through existing detachable methods such as plug-in, snap-in, or spring abutment. The socket 202 and the anode module 9 only need to be compatible in terms of structure and plug-in method. In this application, the socket 202 has a three-block structure, located in three directions respectively. The end side of the anode module 9 slides into the three blocks, and positioning is achieved by friction, which meets the requirements of shaking use.

[0034] The slot 2011 and the transmission part 301 of the control lever 3 can be mutually compatible irregular structures, such as quadrilateral structures, which can slide along the axial direction but always maintain the ability to rotate.

[0035] Furthermore, there are two positioning rods 4, which are located on both sides of the transmission part 301 respectively; the limiting plate 101 has two limiting holes 1011, and the positions of the limiting holes 1011 and the positioning rods 4 correspond one-to-one. When the positioning rods 4 rotate with the control rod 3, the positioning rods 4 move upward and abut against the top plate 102.

[0036] In use, there are two positioning rods 4, located on both sides of the control rod 3 or the transmission part 301 respectively. When swinging, they can more effectively impact the top plate 102. At the same time, when the support plate 2 needs to be horizontally positioned, the two positioning rods 4 are inserted into the limiting holes 1011 on both sides respectively, making the positioning support more stable.

[0037] Furthermore, it also includes a compression spring 5, one end of which acts on the control lever 3 and the other end of which acts on the base 1, for providing force to move the positioning lever 4 closer to the limiting plate 101. The control lever 3 has a handle 302 on the end side located outside the base 1, and the control lever 3 is rotatably mounted on the base 1.

[0038] During use, the compression spring 5 automatically resets and allows for rotational positioning. When the control lever 3 is pulled outward from the base 1, the compression spring 5 compresses, the positioning rod 4 exits the limiting hole 1011, and after rotation, the end of the positioning rod 4 can slide on the side of the limiting plate 101 or move away from the limiting plate 101. When it is necessary to keep the support plate 2 in an inclined state, such as when controlling the flow of additives, the control lever 3 is released, and the positioning rod 4 abuts against the limiting plate 101. Under the pressure of the compression spring 5, sufficient friction can be provided between the positioning rod 4 and the limiting plate 101 to keep the support plate 2 in an inclined position, eliminating the need for manual positioning. The frictional positioning capability can be enhanced through surface treatment or by adding a rubber pad to the end of the positioning rod 4.

[0039] When the positioning rod 4 needs to be inserted into the limiting hole 1011, the control rod 3 is slowly rotated to bring the positioning rod 4 close to the limiting hole 1011. Under the pressure of the compression spring 5, the positioning rod 4 can be inserted into the limiting hole 1011 and can remain in the inserted state.

[0040] The control lever 3 rotates on the base, which provides stable support for the control lever 3, and the handle 302 makes it convenient for the operator to operate and rotate the control lever 3.

[0041] Furthermore, it also includes: a mounting bracket 6, which is mounted on the base 1 and located next to the support plate 2;

[0042] A support frame 7 is rotatably mounted on the upper end of the mounting frame 6 and located above the anode module 9. A syringe 8 is slidably mounted on the support frame 7, with the outlet of the syringe 8 opposite to the anode module 9. The support frame 7 has a through groove 701, within which a syringe 8 is slidably mounted.

[0043] In use, the support frame 7 can hold the syringe 8, reducing the need for manual lifting. The support frame 7 rotates on the mounting frame 6, and the syringe 8 can slide on the support frame 7, so the movement range of the syringe 8 can cover the area above the anode module 9. The through groove 701 on the support frame 7 is elongated, and the main body of the syringe 8 can slide within the through groove 701. The protruding edge of the syringe 8 slides on the support frame 7 to form upward support, making it convenient to remove and insert the syringe 8. It can be seen that the discharge end of other feeding devices can also be placed on the support frame 7.
