Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically a detection device for a proton exchange membrane. Background Technology

[0002] Detection devices are equipment used to measure, monitor, and evaluate various parameters such as physical quantities, chemical composition, and biological characteristics. They are widely used in industries, medicine, environmental monitoring, and scientific research. Through components such as sensors, analyzers, and measuring instruments, they achieve accurate detection of target objects, providing important data for production process control, quality assurance, safety protection, and decision support. The development trend of detection devices is towards high precision, rapid response, intelligence, and multi-functional integration to meet the ever-increasing technological demands and complex application scenarios.

[0003] A proton exchange membrane (PEM) testing device is a specialized instrument for evaluating and monitoring the performance of PEMs. It is crucial in fuel cells, water electrolysis, and other membrane separation technologies. This device uses precise measurement methods, such as electrochemical impedance spectroscopy, current-voltage curve testing, membrane resistance, and ion conductivity analysis, to detect key indicators of the PEM, including conductivity, selectivity, stability, and durability. Furthermore, the device may integrate temperature and humidity control units and automated testing systems to ensure accurate and repeatable testing under simulated real-world operating conditions. The development and optimization of PEM testing devices are of great significance for improving the efficiency, reliability, and lifespan of energy conversion devices such as fuel cells.

[0004] However, existing proton exchange membrane testing devices, particularly those using traditional fixed connections, cannot achieve different stretching methods on both sides of the proton exchange membrane, such as simultaneous stretching, stretching one side while keeping it stationary, or stretching with different forces. This limits the ability to simulate various stress states in practical applications, leading to biased test results. Furthermore, the stretching force cannot be adjusted for proton exchange membranes of different materials, thicknesses, or structures, resulting in either excessive force damaging the membrane material or insufficient force failing to accurately assess membrane performance. Additionally, uneven distribution of the stretching force on the membrane causes localized stress concentration, leading to membrane material damage or inaccurate performance assessments. To address these issues, a proton exchange membrane testing device is proposed. Utility Model Content

[0030] 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.

[0031] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0032] Reference Figure 1 and Figure 2This utility model discloses a proton exchange membrane testing device, including a processing platform 1, which provides a testing environment. Each slider 14 has a clamp 15 on its top, which can clamp and fix the proton exchange membrane to be tested. The other end of the housing 3 is equipped with a control panel 24, which is electrically connected to an air pump 5. The control panel 24 can adjust the gas volume between each sealing plate 8. The control panel 24 is electrically connected to a first electric valve 4, a second electric valve 7, and a third electric valve 11.

[0033] Reference Figure 2 A processing platform 1 has an air pipe 2 that is fixedly connected to its bottom. A housing 3 is also fixedly connected to the bottom of the air pipe 2. A first electric valve 4 is installed on the outer wall of the air pipe 2. Transport pipes 6 are fixedly connected to both sides of the housing 3 and are also fixedly connected to the processing platform 1. A second electric valve 7 is installed on the outer wall of each transport pipe 6. Evenly distributed sealing plates 8 are slidably connected inside the processing platform 1. Fixing rods 9 are slidably connected to all four sides of one side of each sealing plate 8 and are fixedly connected to the processing platform 1. First springs 12 are fitted at both ends of the outer ring of each fixing rod 9. A through-tube 10 is fixedly connected to one side of each of the two sealing plates 8. A third electric valve 11 is installed on the outer wall of each through-tube 10. Driven by an air pump 5, the air pipe 10... By moving the two sealing plates 8 apart, the two sealing plates 8 slide on the fixed rod 9, thereby compressing the first spring 12 and causing the slide rod 13 to slide within the processing platform 1. This automates the detection process, reduces manual intervention, and improves the accuracy and repeatability of the detection. A slide rod 13 is fixedly connected to one side of each sealing plate 8, and the slide rod 13 penetrates and slides through the processing platform 1. An air pump 5 is installed at one end of the housing 3, and an adjustment assembly is installed at the top of the processing platform 1. Through the sliding of the fixed rod 9 and the sealing plate 8, the slide rod 13 can slide stably within the processing platform 1, ensuring that the tensile force is evenly distributed on the proton exchange membrane, avoiding membrane damage caused by localized stress concentration, and thus helping to improve the accuracy and consistency of the detection results.

[0034] Reference Figure 1 and Figure 3The adjustment assembly includes a slider 14, which is slidably connected to both ends of the top of the processing platform 1. A connecting rod 16 is fixedly connected to one side of the clamp 15. A second spring 18 is fitted onto both ends of the outer ring of the connecting rod 16. A sliding plate 17 is slidably connected to the middle of the outer ring of the connecting rod 16. A fixing plate 23 is fixedly connected to one side of the sliding plate 17, and the fixing plate 23 is fixedly connected to the sliding rod 13. The sliding plate 17 slides on the connecting rod 16, thereby compressing the second spring 18, which in turn causes the connecting rod 16 to drive the clamp 15 to slide on the processing platform 1. This, combined with the previous design of the sealing plate 8, fixing rod 9, and first spring 12, and the current design of the connecting rod 16, second spring 18, and sliding plate 17, forms a multi-stage anti-deviation mechanism. The structure helps to disperse and balance the forces applied to the proton exchange membrane, reducing the impact of off-center loading on the membrane material and improving the accuracy and reliability of detection. One end of each connecting rod 16 is fixedly connected to a limiting rod 19. Each limiting rod 19 has a third spring 20 inside. Both ends of the third spring 20 are fixedly connected to a bearing rod 21, and the bearing rod 21 is slidably connected to the limiting rod 19. One end of each limiting rod 19 is slidably connected to a support rod 22, and the support rod 22 is slidably connected to the bearing rod 21. By allowing the bearing rod 21 to slide into the limiting rod 19, the third spring 20 is compressed, thereby allowing the support rod 22 to slide out of the limiting rod 19. This allows it to adapt to proton exchange membranes of different thicknesses, materials, or structures, achieving a wider detection range.

[0035] Working principle: A designated second spring 18 is fitted onto the connecting rod 16, then the sliding plate 17 slides into the connecting rod 16. The designated second spring 18 is then fitted again, and the bearing rod 21 slides into the limiting rod 19, thus compressing the third spring 20. The support rod 22 then slides out of the limiting rod 19. Due to the rebound of the third spring 20, the bearing rod 21 slides out of the limiting rod 19 and into the support rod 22, thus limiting and fixing the support rod 22. Then, the control panel 24 drives the air pump 5, which in turn controls the second electric valve 7, thereby controlling the volume of gas between the two sealing plates 8 and the inner wall of the processing platform 1. Simultaneously, the third electric valve 1... The linkage between the 1 and the tube 10 controls the volume of gas between the two side sealing plates 8 and the middle two side sealing plates 8. Then, the air pump 5 is driven and the first electric valve 4 is controlled, so that the middle two side sealing plates 8 slide within the processing platform 1, and the two side sealing plates 8 slide on the fixed rod 9, thereby compressing the first spring 12. Then, through the rebound of the first spring 12, the slide rod 13 slides within the processing platform 1. Then, through the connection of the fixed plate 23, the slide plate 17 slides on the connecting rod 16, thereby compressing the second spring 18, so that the clamp 15 drives the slider 14 to slide a specified distance on the processing platform 1, thereby performing tensile testing on the required proton exchange membrane.
