Introduction The reliability and performance of hydrogen fuel cell systems play a crucial role in promoting the development of hydrogen energy technology. In order to ensure the stable operation of various series of hydrogen fuel cell systems under different environmental conditions, our company has developed the UC series walk-in hydrogen fuel cell system environmental test chamber. Advanced equipment designed specifically for hydrogen fuel cell systems can undergo environmental simulation tests in accordance with standards such as GB/24554-2009. The experimental module includes core components such as the cabin, refrigeration unit, oil heating unit, high-altitude simulation unit, and fresh air unit, ensuring precise environmental control and simulation of the hydrogen fuel cell system during the testing process. It has the ability to simulate the environment under a combination of multiple factors such as temperature, humidity, and low air pressure in the natural environment (requiring an optional high-altitude simulation system). After integrating the software and hardware systems with the test bench, the working status of the test chamber can be remotely monitored and controlled through the main control system of the test bench. Parameters such as temperature, humidity, and height can be individually programmed and controlled, or linked and controlled through the main control program of the test bench to ensure the accuracy and controllability of the test process.
