[0002] The proton exchange membrane (PEM) is the core component of a proton exchange membrane fuel cell (PEMFC) and plays a crucial role in its performance. It not only acts as a barrier but also conducts protons. PEMFCs offer advantages such as low operating temperature, fast start-up, high specific power, simple structure, and ease of operation, making them widely recognized as the preferred energy source for electric vehicles and stationary power plants. The PEMFC is typically produced by roller coating or spraying a polymer raw material solution onto a substrate, allowing it to enter the micropores of the supporting membrane and coalesce on its surface to form a composite membrane.

The sliding plate moves to drive the spraying head. The coating material enters the spraying head from the storage tank through the connecting pipe and is then evenly sprayed onto the exchange membrane. An infrared dryer can dry the exchange membrane, thereby improving working efficiency and the quality of the exchange membrane.

[0004] However, the device still has shortcomings: for proton exchange membranes that are in continuous transport, the coating efficiency is low, and the fixed position of the nozzle is not conducive to composite processing of raw materials of different widths. Utility Model Content

[0025] Example 1

[0026] like Figures 1-4As shown, the proton exchange membrane composite device proposed in this utility model includes a frame 1, a winding assembly, a support 12, a drive mechanism A, a pressure roller 22, and a drying assembly. A belt roller 2 is installed at each end of the frame 1, and the two belt rollers 2 are connected by a belt 3. A support plate 4 is installed on the frame 1 to support the weighing end of the belt 3. The winding assembly is located at the output end of the frame 1 and includes a winding roller 6 and a motor A7. An extension arm A and an extension arm B are installed at the output end of the frame 1. A slot is provided on the extension arm B, and a movable plate is rotatably installed on the extension arm A. The winding roller 6 is rotatably connected to the movable plate, and the other end of the winding roller 6 is inserted into the slot. The body of the motor A7 is connected to the movable plate, and the output end of the motor A7 is connected to the roller shaft of the winding roller 6. The winding assembly winds up the proton exchange membrane in the working state. A support bracket 12 is mounted on the frame 1. Two hollow shafts 13, rotatably connected to each other, are spaced apart on the support bracket 12. A guide plate 14, communicating with each hollow shaft 13, is mounted at the lower end of each shaft. Several nozzles 15, communicating with each guide plate 14, are equidistantly arranged along the length of each guide plate 14. A feeding assembly for supplying paint to the hollow shafts 13 is mounted on the support bracket 12. The feeding assembly includes a storage tank 18 and a liquid pump 19, both mounted on the support bracket 12. The input end of the liquid pump 19 has a suction pipe, and the output end has a discharge pipe 20. The other end of the suction pipe is inserted into the storage tank 18 and located below the liquid surface. The other end of the discharge pipe 20 has two branch pipes, which are inserted into the corresponding hollow shafts 13 and rotate coaxially with and communicate with them. A drive mechanism A is mounted on the support bracket 12 and drives the two hollow shafts 13 to rotate synchronously and in the same direction. The drive mechanism A includes a transmission assembly 16 and a drive assembly 17. The transmission assembly 16 includes a synchronous belt and two pulleys. The two pulleys are coaxially connected to the hollow shafts 13 on their respective sides, and the two pulleys are connected by the synchronous belt. The drive assembly 17 includes gear A, gear B, and motor B. Gear A is coaxially connected to one of the hollow shafts, and gear B is coaxially connected to the rotating shaft on the bracket 12. Gear B meshes with gear A. The body of motor B is connected to the bracket 12, and the output end of motor B is connected to the rotating shaft. The pressure roller 22 is movably mounted on the bracket 12 and is located between two guide plates 14. The drive mechanism B, which drives the pressure roller 22 to rise or fall, is mounted on the bracket 12. The drive mechanism B includes a U-shaped frame 21 and a cylinder B23. The opening of the U-shaped frame 21 faces downward and is located above the support plate 4. The U-shaped frame 21 is slidably connected to the bracket 12. The body of the cylinder B23 is connected to the bracket 12. The output end of the cylinder B23 is connected to the U-shaped frame 21. The pressure roller 22 is located inside the opening of the U-shaped frame 21 and is rotatably connected to it. A flexible sponge sleeve coaxial with it is sleeved on the pressure roller 22.The drying assembly is mounted on the frame 1 and close to its output end. The drying assembly includes a protective cover 24 and infrared heating tubes 25. The protective cover 24 is connected to the frame 1 and its opening faces downward. There are multiple infrared heating tubes 25, and all infrared heating tubes 25 are located inside the protective cover 24 and connected to its inner wall. The drying assembly dries the coated exchange membrane.

[0027] In this embodiment, the equipment is powered on and debugged. Then, cylinders A81 and B23 are connected to the output pipes on the external air tank, and the input pipe of the air tank is connected to the external air compressor. Simultaneously, the sponge sleeve on the pressure roller 22 absorbs an appropriate amount of polymer raw material. The absorption standard is that when the pressure roller 22 comes into contact with the support membrane, it will no longer absorb polymer from the support membrane. The bottom surface of the support membrane is placed on the belt 3, and its end is pulled and... Figure 1 As shown, the end of the film is fixed to the roll on the take-up roller 6. Cylinder B23 presses down the U-shaped frame 21 and the pressure roller 22 flexibly presses the supporting film. Then, the liquid pump 19 is started. The liquid pump 19 draws liquid polymer from the storage tank 18 and injects it into the hollow shaft 13. The polymer is sprayed out in a mist form through the micro-holes of the nozzle and adheres to the surface of the film. Then, the motor A7 is started. The motor A7 drives the take-up roller 6 to rotate. The supporting film is driven and the belt runs adaptively to avoid the supporting film being damaged by friction on the belt. The left nozzle 15 first sprays the surface of the supporting film. Then, the pressure roller 22 squeezes the sprayed area to promote the polymer to enter the micro-holes of the supporting film. Then, the right nozzle 15 sprays the supporting film a second time to make its surface completely flat without dents. After the spraying is completed, the film passes under the protective cover 24 and is heated by the infrared heating tube 25 to dry quickly. The dried film is wound onto the roll on the take-up roller 6. After winding is completed, the take-up roller 6 can be flipped up to easily remove the roll and replace it.

[0028] Example 2

[0029] like Figures 1-3 As shown, the proton exchange membrane composite device proposed in this utility model, compared with Embodiment 1, has a guide roller 5 arranged on the frame 1 near its output end. A cutting assembly is arranged between the guide roller 5 and the take-up roller 6. The cutting assembly includes a fixed plate 8, a cylinder A81, and a cutter 11. The two ends of the fixed plate 8 are respectively connected to the extension arm A and the extension arm B. A slide 10 is arranged on the fixed plate 8 and slidably connected thereto. The cutter 11 is connected to the slide 10 and located below the fixed plate 8. The body of the cylinder A81 is connected to the fixed plate 8, and the output end of the cylinder A81 is connected to the slide 10. A distance sensor 9 is arranged on the fixed plate 8 on the side facing the take-up roller 6. A PLC controller is arranged on the frame 1. The PLC controller is electrically connected to the distance sensor 9 and the motor A7.

[0030] In this embodiment, the film passes around the guide roller 5 and through the space between the fixed plate 8 and the cutter 11, and its end is finally fixed on the winding roller 6. During the film winding process, the thickness of the film roll on the winding roller 6 gradually increases. The distance sensor 9 monitors the film roll thickness in real time. When the set value is reached, the motor A7 stops, the cylinder A81 pulls up the slide 10, and the cutter 11 cuts the film. Then the cutter 11 descends and resets. This structure makes the thickness of each roll of film more uniform, that is, the length difference of each roll of film is very small, and the cutting is stable, which is more efficient than manual cutting.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
