The second clamping plate 8 is slidably connected to the interior of the second clamping plate 10. The two second clamping plates 8 are fixed on both sides of the interior of the first clamping plate 4, and the spring 29 provides support and also automatically resets the seal housing 1 and 2, facilitating quick assembly and disassembly.

[0023] A sealing strip 11 is fixedly connected to the interior of the sealing shell 2. There are multiple sealing strips 11. A proton membrane 12 is slidably connected to the outer wall of the sealing strip 11. A diffusion layer 13 is fixedly connected to the interior of the proton membrane 12. A sealing ring 14 is fixedly connected to the interior of the proton membrane 12. The sealing ring 14 is slidably connected to the outer wall of the sealing strip 11 and fixedly connected to the outer wall of the diffusion layer 13. The diffusion layer 13 is sealed and fixed to the left interior of the proton membrane 12 via the sealing ring 14. A bipolar plate 15 is fixedly connected to the outer wall of the proton membrane 12. The bipolar plate 15 is slidably connected to the outer wall of the sealing strip 11. A diffusion layer 2 16 is fixedly connected to the interior of the proton membrane 12. A sealing ring 2 17 is fixedly connected to the interior of the proton membrane 12. The sealing ring 2 17 is fixedly connected to the outer wall of the diffusion layer 2 16. The diffusion layer 2 16 is fixedly fixed to the right interior of the proton membrane 12 via the sealing ring 2 17. The sealing ring 17 is slidably connected to the outer wall of the sealing strip 11, and the outer wall of the proton membrane 12 is fixedly connected to the bipolar plate 18.

[0024] Working principle:

[0025] During use, the diffusion layer 13 and sealing ring 14 are fixed to the left interior of the proton membrane 12, the diffusion layer 2 16 and sealing ring 2 17 are fixed to the right interior of the proton membrane 12, and the bipolar plate 15 is fixed to the left outer wall of the proton membrane 12, and the bipolar plate 2 18 is fixed to the right outer wall of the proton membrane 12 to achieve a sealing effect. The assembled and fixed proton exchange membrane is passed through the sealing strip 11. At this time, the two clamping plates 2 8 are moved to the sides, causing them to slide and compress the spring 2 9, and the clamping plate 1 4 is inserted into the interior of the clamping groove 1 6. After releasing the two clamping plates 2 8, the elasticity of the two springs 2 9 drives the two clamping plates 2 8 to automatically return to the interior of the clamping plate 1 4, thereby achieving a quick installation effect. At the same time, the elasticity of the spring 1 5 supports the clamping plate 1 4 to prevent it from sliding out of the sealing shell 2 2. During disassembly, the second card plate 8 is also pushed to both sides to make the second card plate 8 slide to both sides. During the sliding process, the second card plate 8 is pulled out from the inside of the first card plate 4, so that the first card plate 4 can be taken out from the inside of the sealing shell 2, thereby achieving the effect of quickly separating and disassembling the sealing shell 1 and the sealing shell 2.
