High temperature fuel cell testing fixtureIt is a key equipment specifically designed to evaluate the performance of fuel cells in high-temperature environments, and its design needs to meet core requirements such as precise temperature control, reliable fixation and sealing, and precise measurement.
High temperature fuel cell testing fixtureCore functions and design points:
Accurate temperature control
Heating system: Using resistance wire heating furnace, infrared heating lamp and other components, high temperature environment simulation is achieved by converting electrical energy into thermal energy. For example, the resistance wire heating furnace is suitable for small fixtures, with fast heating speed and uniform temperature; Infrared heating lamps are suitable for large or complex structures, providing a more uniform heating effect.
Temperature feedback and regulation: Built in temperature sensors (such as thermocouples) monitor temperature in real time and provide feedback to the control system, dynamically adjusting heating power to maintain temperature stability and ensure repeatable testing conditions.
Reliable fixation and sealing
Mechanical fixation: The battery is fixed by customized fixture structures (such as mechanical clamping, threaded connections) to prevent displacement or vibration during the testing process from affecting data accuracy.
High temperature resistant sealing: using materials such as ceramic gaskets and silicone sealing rings to prevent high-temperature gas leakage or external impurities from entering. For example, the SSC-SOFCSOEC12 series fixture fixes the battery in a corundum tube or quartz tube, seals the anode surface with high-temperature ceramic glue, and seals the cathode chamber in a "free state" through the gravity of the quartz tube, reducing the risk of battery damage.
Accurate measurement and data collection
Electrochemical performance measurement: Connect an electrochemical workstation or battery charge and discharge tester to measure parameters such as voltage, current, capacity, internal resistance, etc., and analyze the battery's charge and discharge characteristics, cycle life, and safety at high temperatures.
Temperature and pressure monitoring: Each battery is equipped with temperature and voltage sensors to record data in real-time; Some fixtures can monitor changes in gas pressure and assist in the study of thermal runaway mechanisms.
