Description

Technical Field

[0001] This utility model relates to the field of fuel cell technology, and in particular to a high-pressure, high-temperature dual-chamber solid oxide fuel cell. Background Technology

[0002] A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy. It generates electrical energy by supplying hydrogen or methanol fuel and oxygen from the air to the anode and cathode, respectively, and an electrochemical reaction occurs under the action of electrode catalysts, while producing water or carbon dioxide as byproducts.

[0003] A search revealed Chinese Patent Publication No. CN205231176U, which discloses a solid oxide fuel cell electrode and a solid oxide fuel cell. The electrode body, comprising a porous structure disposed on an electrolyte layer, features multiple gas channels formed on the porous electrode body. Each gas channel extends in a first direction and has opposing first and second ends. At least one of the first and second ends has an opening to connect the gas channel to the outside. These gas channels allow for the regulation and optimization of gas diffusion within the electrode, effectively mitigating or avoiding the uneven distribution of reaction sites and the resulting uneven temperature field distribution commonly found in solid oxide fuel cells during operation. Furthermore, the gas channels facilitate the timely removal of water generated at the anode or cathode. However, in practical use, the lack of a high-temperature, high-pressure environment results in a relatively slow electrochemical reaction rate within the fuel cell. Due to activation energy limitations, the effective collision frequency between reaction particles is low during the oxidation of hydrogen at the anode and the reduction of oxygen at the cathode, making it difficult for the electrode reaction to proceed rapidly. This hinders the increase of the battery's output power, reducing the device's practicality and failing to meet user needs. Utility Model Content

[0004] To overcome the above shortcomings, this invention provides a high-pressure, high-temperature dual-chamber solid oxide fuel cell, aiming to improve the problem of low electrochemical reaction rate in existing solid oxide fuel cells.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-pressure, high-temperature dual-chamber solid oxide fuel cell, comprising a heating furnace, a reaction tube disposed inside the heating furnace, and support seats disposed on both the upper and lower sides of the reaction tube. A fixing ring is fixedly connected to an adjacent side of each of the two support seats, a support ring is fixedly connected to an adjacent side of each of the two fixing rings, and a hollow plate is fixedly connected to an adjacent side of each of the two support rings. The upper and lower ends of the reaction tube pass through corresponding hollow plates, support rings, and fixing rings sequentially. A fixing block is fixedly connected to the far side of each of the two support seats, and an air inlet pipe is fixedly connected to the inner side of each of the two fixing blocks. Each of the two air inlets has a fixed block, a support base, and a reaction tube passing through one of its adjacent ends.

The rotating rod is rotatably connected to the rear right end of the hollow plate. A driving bevel gear is fixedly connected to both the left and right sides of the outer wall of the rotating rod. A bidirectional threaded rod is rotatably connected to both the left and right sides of the inner front end of the hollow plate. A driven bevel gear is fixedly connected to the rear end of each of the two bidirectional threaded rods. The two driven bevel gears are respectively meshed with the corresponding driving bevel gears. First movable clips are threaded to the front and rear sides of the outer walls of the two bidirectional threaded rods. Connecting rods are rotatably connected to the inner sides of multiple first movable clips. Second movable clips are rotatably connected to one end of each of the multiple connecting rods. One side of each of the multiple second movable clips is fixedly connected to a corresponding support plate. Clamping jaws are fixedly connected to adjacent sides of the two support plates.

[0008] By using the above technical solution, rotating the rotating rod can drive the gripper to detach from the reaction tube, making it easy to disassemble the high-pressure, high-temperature dual-chamber solid oxide fuel cell and reducing the workload of the staff.

[0009] As a further description of the above technical solution: The right end of the rotating rod passes through the hollow plate and is fixedly connected to a knob. The inner dimensions of the gripper match the dimensions of the reaction tube.

[0010] The above technical solution facilitates the rotation of the rotating rod by the staff and ensures that the gripper can be firmly fixed.

[0011] As a further description of the above technical solution: The hollow plate has sliding grooves on both the left and right ends, and the inner sides of the two sliding grooves are slidably connected to the corresponding first movable cards.

[0012] The above technical solution can limit the movement of the first movable card, so that it can only slide inside the slide groove.

[0013] As a further description of the above technical solution: Both of the two fixed rings have assist rod insertion ports on their front and rear sides, and both of the two support seats have temperature measuring interfaces fixedly connected to their left ends on opposite sides.

[0014] By using the above technical solution and connecting a thermometer to a temperature measurement interface, the internal reaction temperature of the high-pressure, high-temperature dual-chamber solid oxide fuel cell can be clearly understood.

[0015] As a further description of the above technical solution: Mounting blocks are fixedly connected to the left and right sides of both support rings, and a constant temperature water bath jacket is fixedly connected to one side of each of the mounting blocks.

[0016] Through the above technical solution, the constant temperature water bath jacket can control the reaction temperature inside the high-pressure, high-temperature dual-chamber solid oxide fuel cell.

[0017] As a further description of the above technical solution: A fixing plate is fixedly connected to the upper outer part of the reaction tube. Screws are threaded around the top of the fixing plate, and the bottom ends of the screws pass through the fixing plate and are threadedly connected to the heating furnace.

[0018] The above technical solution allows for easy removal of the reaction tube from the heating furnace.

[0019] As a further description of the above technical solution: The rear wall of the heating furnace is fixedly connected to both the upper and lower sides with brackets, and the rear sides of both brackets are fixedly connected to mounting plates.

[0020] The above technical solution enables convenient installation of this high-pressure, high-temperature dual-chamber solid oxide fuel cell.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the start-up of the heating furnace causes the temperature of the reaction tube to rise, providing a high-pressure reaction environment for the high-pressure, high-temperature dual-chamber solid oxide fuel cell. Furthermore, by introducing high-pressure combustible gas and high-pressure oxygen through the upper and lower air inlets respectively, the high-pressure state inside the high-pressure, high-temperature dual-chamber solid oxide fuel cell can be maintained. The high-temperature and high-pressure state can accelerate the internal reaction rate of the high-pressure, high-temperature dual-chamber solid oxide fuel cell, improve the practicality of the high-pressure, high-temperature dual-chamber solid oxide fuel cell, and meet the needs of users.

[0022] 2. In this utility model, the rotating rod drives the active bevel gear to rotate. Due to the interaction between the driven bevel gear and the active bevel gear, the driven bevel gear drives the bidirectional threaded rod to rotate. At this time, the first movable clamp drives the second movable clamp to move through the connecting rod. When the second movable clamp moves, it will drive the gripper to disengage from the reaction tube through the support plate. This allows the high-pressure, high-temperature dual-chamber solid oxide fuel cell to be disassembled and maintained, making the disassembly work more convenient and reducing the workload of the staff.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a high-pressure, high-temperature dual-chamber solid oxide fuel cell, comprising a heating furnace 1, a reaction tube 3 disposed inside the heating furnace 1, and support seats 4 disposed on both the upper and lower sides of the reaction tube 3. A fixing ring 5 is fixedly connected to an adjacent side of each of the two support seats 4, and a support ring 6 is fixedly connected to an adjacent side of each of the two fixing rings 5. A hollow plate 14 is fixedly connected to an adjacent side of each of the two support rings 6. The upper and lower ends of the reaction tube 3 pass through the corresponding hollow plate 14, support ring 6, and fixing ring 5 sequentially. A fixing block 9 is fixedly connected to the opposite side of each of the two support seats 4, and an air inlet pipe 7 is fixedly connected to the inner side of each of the two fixing blocks 9. An adjacent end of each of the two air inlet pipes 7 passes through the fixing block 9, the support seat 4, and the reaction tube 3. An electrolyte sheet 8 is fixedly connected to the middle of the inner side of the reaction tube 3. An air inlet 10 is fixedly connected to the right side of each of the two fixing blocks 9. The right ends of the two air inlets 10 pass through the fixing blocks 9 and are connected to the air inlet pipe 7. An electrode 11 is fixedly connected to the opposite end of each of the two fixing blocks 9. An air outlet 12 is fixedly connected to the right end of the opposite side of each of the two support seats 4. The two air outlets 12 pass through the corresponding support seats 4 and are connected to the reaction tube 3. A disassembly mechanism 2 is provided on the inner side of each of the two hollow plates 14. The disassembly mechanism 2 is used to facilitate the disassembly and maintenance of the high-pressure high-temperature dual-chamber solid oxide fuel cell. Mounting blocks 20 are fixedly connected to the left and right sides of each of the two support rings 6. A constant temperature water bath jacket 17 is fixedly connected to one side of each of the multiple mounting blocks 20. Specifically, in using this high-pressure, high-temperature dual-chamber solid oxide fuel cell, combustible gas enters the fuel cell through the top inlet 10, follows the path of the inlet pipe 7, and eventually reaches the vicinity of the electrolyte plate 8. Simultaneously, oxygen enters through the bottom inlet 10, also following the guidance of the inlet pipe 7, reaching the vicinity of the electrolyte plate 8. At this point, the heater 1 starts, and the heat it generates is transferred to the reaction tube 3, causing the temperature within the entire reaction tube 3 to gradually rise. When the temperature reaches the predetermined reaction temperature, the chemical reaction begins. After the reaction process is complete, the generated gas is discharged through a high-pressure, high-temperature dual-chamber solid oxide fuel cell. The gas outlets 12 on both sides of the high-pressure high-temperature dual-chamber solid oxide fuel cell are discharged. While the reaction is in progress, the electrodes 11 on both sides are connected to the external power transmission device, so that the generated electrical energy can be transmitted to the outside. In addition, the continuous heating of the furnace 1 and the injection of high-pressure gas into the high-pressure high-temperature dual-chamber solid oxide fuel cell ensure that the entire high-pressure high-temperature dual-chamber solid oxide fuel cell can be maintained in a high-temperature and high-pressure state during the reaction process. This helps to promote the effective reaction between reactants, thereby improving the efficiency and output of the entire system, improving the practicality of the high-pressure high-temperature dual-chamber solid oxide fuel cell, and meeting the needs of users.

[0027] Reference Figure 1 and Figure 4 The disassembly mechanism 2 includes a rotating rod 202 and a support plate 209. The rotating rod 202 is rotatably connected to the rear right end of the hollow plate 14. A driving bevel gear 203 is fixedly connected to both the left and right sides of the outer wall of the rotating rod 202. Two bidirectional threaded rods 204 are rotatably connected to both the left and right sides of the front end of the hollow plate 14. A driven bevel gear 205 is fixedly connected to the rear end of each of the two bidirectional threaded rods 204. The two driven bevel gears 205 mesh with their corresponding driving bevel gears 203. The front and rear sides of the outer walls of the two bidirectional threaded rods 204 are... Each of the first movable clips 206 is threadedly connected to a first movable clip 206. The inner side of each first movable clip 206 is rotatably connected to a connecting rod 207. One end of each connecting rod 207 is rotatably connected to a second movable clip 208. One side of each second movable clip 208 is fixedly connected to a corresponding support plate 209. Adjacent sides of two support plates 209 are fixedly connected to grippers 201. The right end of the rotating rod 202 passes through the hollow plate 14 and is fixedly connected to a knob 13. The inner dimensions of the grippers 201 match the dimensions of the reaction tube 3. Specifically, when maintenance is required on the high-pressure, high-temperature dual-chamber solid oxide fuel cell, first turn knob 13. The rotation of knob 13 will cause the rotating rod 202 to start rotating. During the rotation of the rotating rod 202, it will further drive the active bevel gear 203 to start rotating. Since the driven bevel gear 205 and the active bevel gear 203 are meshed with each other, when the active bevel gear 203 rotates, the driven bevel gear 205 will drive the bidirectional threaded rod 204 to rotate. Since the first movable clip 206 is limited by the slide groove 23, when the bidirectional threaded rod 204 rotates, the first movable clip 206 will drive the second movable clip 208 to move through the connecting rod 207. The movement of the second movable clip 208 will further drive the support plate 209 to move. The movement of the support plate 209 will eventually cause the gripper 201 to loosen, thereby disengaging from the reaction tube 3. This allows the high-pressure, high-temperature dual-chamber solid oxide fuel cell to be disassembled, facilitating subsequent maintenance and inspection work and reducing the workload of the staff.

[0028] Reference Figure 1 , Figure 4 and Figure 5 The hollow plate 14 has a sliding groove 23 on both the left and right sides. The inner sides of the two sliding grooves 23 are slidably connected to the corresponding first movable card 206. The front and rear sides of the two fixed rings 5 ​​are provided with assist rod insertion ports 16. The left ends of the two support seats 4 on the opposite sides are fixedly connected with temperature measuring interfaces 15. Specifically, the slide 23 can limit the movement of the first movable card 206, so that it can only slide inside the slide 23. The assist rod inserted into the assist rod socket 16 can support the high-pressure high-temperature dual-chamber solid oxide fuel cell. The temperature measuring interface 15 can be connected to a thermometer to measure the temperature of the high-pressure high-temperature dual-chamber solid oxide fuel cell.

[0029] Reference Figure 1 and Figure 2 A fixing plate 18 is fixedly connected to the upper part of the outer side of the reaction tube 3. Screws 19 are threaded around the top of the fixing plate 18. The bottom ends of the screws 19 pass through the fixing plate 18 and are threadedly connected to the heating furnace 1. Brackets 21 are fixedly connected to the upper and lower sides of the rear wall of the heating furnace 1. Mounting plates 22 are fixedly connected to the rear sides of the two brackets 21. Specifically, the reaction tube 3 can be removed from the heating furnace 1 by removing multiple screws 19, and the high-pressure, high-temperature dual-chamber solid oxide fuel cell can be easily fixed by the bracket 21 and the mounting plate 22.

[0030] Working principle: When using this high-pressure, high-temperature dual-chamber solid oxide fuel cell, combustible gas enters from the top inlet 10, passes through the inlet pipe 7 and reaches the vicinity of the electrolyte plate 8. Oxygen enters from the bottom inlet 10, passes through the inlet pipe 7 and reaches the vicinity of the electrolyte plate 8. At this time, the heater 1 is started, which drives the temperature of the reaction tube 3 to rise. When the reaction temperature is reached, the reaction begins. After the reaction is completed, the gas can be sent out of the high-pressure, high-temperature dual-chamber solid oxide fuel cell through the outlets 12 on both sides. At this time, the electrodes 11 on both sides are connected to the power transmission device, which can output electrical energy to the outside. Furthermore, through the heating of the heater 1 and the injection of high-pressure gas into the high-pressure, high-temperature dual-chamber solid oxide fuel cell, the high-pressure, high-temperature dual-chamber solid oxide fuel cell can maintain a high temperature and high pressure state during the reaction, promoting the reaction of the reactants. Furthermore, when maintenance is required on the high-pressure, high-temperature dual-chamber solid oxide fuel cell, the knob 13 is rotated. The rotation of the knob 13 will cause the rotating rod 202 to rotate, which in turn will cause the driving bevel gear 203 to rotate. Since the driven bevel gear 205 meshes with the driving bevel gear 203, the driven bevel gear 205 will then cause the bidirectional threaded rod 204 to rotate. Since the first movable clamp 206 is limited by the sliding groove 23, when the bidirectional threaded rod 204 rotates, the first movable clamp 206 will then drive the second movable clamp 208 to move through the connecting rod 207. When the second movable clamp 208 moves, it will then drive the support plate 209 to move. At this time, the support plate 209 will then cause the gripper 201 to disengage from the reaction tube 3, thus enabling the high-pressure, high-temperature dual-chamber solid oxide fuel cell to be disassembled and maintained.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
