Description
Technical Field
[0001] This invention relates to the field of membrane electrode testing technology, specifically a scalable high-throughput membrane electrode testing platform. Background Technology
[0002] Fuel cells are clean, efficient, and pollution-free electrochemical power generation devices that have received widespread attention both domestically and internationally in recent years. Among various types of fuel cells, proton exchange membrane fuel cells (PEMFCs) are widely used in electric vehicle power sources and mobile power sources due to their advantages such as fast start-up at room temperature, low operating temperature, high current density, light weight, small size, long lifespan, and the use of solid electrolytes which simplifies the design of the fuel cell stack's sealing components. They have broad market prospects.
[0003] The core components of a traditional high-throughput membrane electrode testing platform include a multi-channel electrochemical workstation, a customized multi-station testing fixture, a gas supply and humidity control system, a temperature control system, and a data acquisition and analysis module. The multi-station fixture can simultaneously fix multiple membrane electrode samples, and the gas system precisely controls the flow rate and humidity of the reaction gas. In use, the membrane electrode sample is first cut to the appropriate size, placed in the multi-station fixture, and sealed. Then, the gas system is started, and the flow rate, humidity, and operating temperature of the reaction gas are set. After the system parameters stabilize, the test conditions are applied through the electrochemical workstation, and data acquisition is started simultaneously.
[0004] Fuel cells demand extremely high quality and precision from their membrane electrode assemblies (MEAs), as their performance directly determines the stack's output efficiency and lifespan. However, traditional testing devices have significant limitations. They cannot simultaneously acquire multi-dimensional data on the MEA's electrochemical performance and structural integrity in a single test, requiring multiple tests. This is not only time-consuming but also susceptible to errors introduced by environmental changes. In critical electrochemical impedance spectroscopy (EIS) testing, traditional devices often lack sufficient response speed at high frequencies, missing impedance peaks and leading to inaccurate calculations of key parameters such as the MEA's interfacial charge transfer impedance. Furthermore, low-frequency tests suffer from data redundancy, increasing the amount of invalid data processed. More importantly, they lack "dynamic calibration" for environmental factors; temperature drift during testing directly causes deviations in the MEA's conductivity calculation. Summary of the Invention
[0005] Based on the aforementioned problems in existing technologies, the problem this application aims to solve is that fuel cells have extremely high requirements for the quality and precision of membrane electrode assemblies (MEAs), whose performance directly determines the stack's output efficiency and lifespan. However, traditional testing devices have significant limitations, unable to simultaneously acquire multi-dimensional data such as the electrochemical performance and structural integrity of MEAs in a single test. Multiple tests are required, which is not only time-consuming but also prone to errors introduced by environmental changes. In the critical electrochemical impedance spectroscopy (EIS) test, traditional devices have insufficient response speed at high frequencies, often missing impedance peaks, leading to inaccurate calculations of core parameters such as the interfacial charge transfer impedance of the MEAs. Furthermore, data redundancy exists at low frequencies, increasing the amount of invalid data processed. More importantly, they lack "dynamic calibration" for environmental factors; when temperature drift occurs during testing, it directly causes deviations in the calculation of the MEAs's conductivity.

Then, the membrane electrode to be tested is placed on the fixed frame 51 of the device, and the operation status of the device is controlled by the keyboard 14, thereby controlling the rotation of the conveyor belt 531. During the process of the conveyor belt 531 driving the fixed frame 51 to move, the product will pass through multiple modules such as the pressure plate 641 and detector 632 set on the base plate 16 for comprehensive data detection. The reciprocating screw on the conveyor plate 5 is used for this process. 512 enables the turntable 5152 to rotate during the movement of the conveyor plate 5, which in turn drives the connecting shaft 515 to rotate. The rotating connecting shaft 515 drives the reciprocating screw 512 to rotate, which in turn drives the scraper 514 to move back and forth, thereby cleaning and flattening the anion exchange membrane on the fixed frame 51. Furthermore, the host 15 integrates the environmental control functions required for anion exchange membrane testing, such as temperature and humidity, gas atmosphere, electrochemical characterization impedance, polarization curve, parameter monitoring pressure, leakage, and gas purity, into independent standardized modules.
