[0002] A fuel cell is a power generation device that converts the chemical energy present in a fuel and an oxidant directly into electrical energy. The main structure of a fuel cell consists of bipolar plates and a membrane electrode. After assembling multiple sets of bipolar plates and membrane electrode, the cell cover is installed, compressed using a pressurizing device, and then connected and reinforced with connectors.

[0003] Currently, after the battery is assembled, it is placed on a workbench. Hydraulic equipment then applies pressure from top to bottom on the top of the battery cover, allowing the rubber gaskets surrounding the bipolar plates to completely seal the battery and achieve a certain degree of assembly tightness, which helps hydrogen flow smoothly between the cells. A series of sealing tests are then performed. However, in most cases, placing the battery below the hydraulic working end relies heavily on the worker's operational experience, which can easily lead to poor alignment, affecting the uniformity of the battery during pressure, resulting in poor sealing in some areas of the battery, and reducing battery production efficiency.

[0016] To more clearly understand the above-mentioned objects, features, and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein may be combined with each other unless they conflict. For ease of description, the words "upper," "lower," "left," and "right" appearing below merely indicate the same directions as in the drawings themselves and do not limit the structure.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Examples, such as Figure 1 、 Figure 2 and Figure 3As shown, the fuel cell production tooling provided by the present invention includes a pad 1. The pad 1 is a rectangular structure and is provided with angle plates 2 at its corners. The angle plates 2 are provided with fixing holes 21. Bolts are inserted into the fixing holes 21 and the bottom plate 44 of the positioning plate group 4 to fix the device on the workbench of the pressurizing equipment. On this basis, the pad 1 provided by the present invention is provided with an L-shaped mounting port 11 and a number of through holes 12 evenly distributed around the mounting port 11. A push plate 3 is slidingly provided in the mounting port 11. A dovetail slider 31 is provided at the bottom of the push plate 3. The dovetail slider 31 slides with the dovetail groove 13 provided on the pad 1. The pad 1 is provided with a positioning plate group 4 on the side close to the push plate 3. The positioning plate group 4 includes a side positioning plate 41. The plate surface of the side positioning plate 41 is close to the edge of the mounting port 11. The top of the side positioning plate 41 An upper positioning plate 42 is provided, and the upper positioning plate 42 is suspended above the installation port 11. A reinforcing plate 43 is provided on the side of the side positioning plate 41 facing away from the installation port 11. A bottom plate 44 is provided at the bottom of the reinforcing plate 43 and the side positioning plate 41. A connecting hole is provided on the bottom plate 44. A positioning rod group 5 is provided on the pad 1 in the front direction of the push plate 3. The positioning rod group 5 includes a pair of insertion rods 51 connected to the through hole 12. A cross plate 52 is provided on the insertion rod 51. The width and height of the cross plate 52 are both smaller than the width and height of the fuel cell.

[0019] Specifically, the push plate 3 is used to place the assembled fuel cell. Under manual operation, the push plate 3 pushes the fuel cell along the matching direction of the dovetail slider 31 and the dovetail groove 13. The side positioning plate 41 and the upper positioning plate 42 respectively position the side and top of the fuel cell. The insertion rod 51 constrains the front end position of the fuel cell. At the same time, the cross plate 52 directly contacts the bipolar plates between the battery covers to prevent the bipolar plates from being seriously offset during the pressurization process, thereby providing a fixed position for the assembled fuel cell, so that the pressurization action of the hydraulic equipment produces uniform force and reaction force on the fuel cell, and the rubber sealing gasket around the bipolar plate completely seals the battery, ensuring the sealing quality of the fuel cell after pressurization, thereby improving the battery production efficiency, and the work utilization rate is high and the practicality is strong.

[0020] To improve the positioning effect of the positioning rod assembly 5 on the front end of the fuel cell, the cross plate 52 provided in the present invention includes a horizontal section 521 and a vertical section 522. The horizontal section 521 is provided with a first guide groove 523 running along its length, and the vertical section 522 is provided with a second guide groove 524 that cooperates with the first guide groove 523. The horizontal section 521 and the vertical section 522 are located on the same vertical plane with respect to the side facing the fuel cell. Both ends of the horizontal section 521 are provided with U-shaped openings 525 that engage with the upper half of the insertion rod 51. The upper half of the insertion rod 51 has a smaller diameter than the lower half and is provided with a sleeve 53. A positioning screw plug 54 is provided at the top of the insertion rod 51. Both the horizontal section 521 and the vertical section 522 avoid the battery cover and directly contact the edge of the bipolar plate, i.e., the main body of the fuel cell. Furthermore, the actual position of the vertical section 522 on the horizontal section 521 can be flexibly adjusted while always maintaining a cross connection with the horizontal section 521. Furthermore, the horizontal section 521 can quickly establish a connection with the two insertion rods 51 through the U-shaped openings 525 at both ends, and the actual position of the insertion rods 51 on the pad 1 is determined according to the position of the through hole 12 selected by it, so the cross plate 52 and the two insertion rods 51 have a certain fine-tuning space; the use of the sleeve 53 and the positioning screw plug 54 can prevent the cross plate 52 from moving freely up and down.

[0021] In order to improve the alignment quality between the push plate 3 and the pad 1, the utility model is provided with a pair of positioning columns 32 at the front end of the push plate 3, and a positioning blind hole 14 cooperating with the positioning columns 32 is provided in the mounting port 11, thereby ensuring that the push plate 3 has a fixed position after delivering the fuel cell to the pressurizing station, and a better pressure-bearing position can be obtained by simply placing the fuel cell against the positioning plate group 4 and the positioning rod group 5.

[0022] To prevent the push plate 3 from sliding freely back and forth after being installed, the present invention provides side grooves distributed along the circumference of the side of the backing plate 1. A C-shaped locking plate 6 is installed in the side groove and slides with the three side surfaces. The movement direction of the locking plate 6 is perpendicular to that of the push plate 3. The side of the push plate 3 is provided with a shoulder 33 that cooperates with the locking plate 6. The locking plate 6 can slide along the right side of the backing plate 1. When it is fully pushed into the side groove, it directly locks into position with the shoulder 33, thus preventing the push plate 3 from sliding freely back and forth, thereby ensuring the stability of the fuel cell during the pressurization process.

[0023] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
