The hydrogen fuel cell system stack environmental test chamber is a device specially used to test and simulate the working environment of hydrogen fuel cell stacks. It can simulate temperature, humidity, pressure and other conditions in a hydrogen fuel cell system to evaluate the performance and reliability of the stack under different operating conditions.

As the core component of
hydrogen fuel new energy vehicles, the hydrogen fuel cell engine system must involve various environmental simulation tests to meet the reliability, stability, safety and other tests of the hydrogen fuel cell engine system under different environmental conditions. These factors also need to be considered when designing the environmental test chamber for the hydrogen fuel cell system stack.
"HUANYI Instruments" has made relevant design requirements for various environmental simulation tests of hydrogen fuel cell stack engine systems, such as hydrogen fuel cell stack engine low-temperature cold start, plateau altitude and other tests.
Design analysis of hydrogen fuel cell system stack environmental test chamber:
1. Structural design based on wind tunnel theory;
2. Through scientific air flow field design and air flow organization analysis, ensure uniform temperature and humidity in the cabin.
3. Built-in or external main cold start temperature control test device to reduce cold start test time;
4. Built-in or external auxiliary cooling temperature control test device;
5. According to user requirements, optional intake and exhaust plateau low pressure simulation systems;
6. Thermal balance capability: loading time 5~10min;
7. Dynamic return time of fuel cell thermal equilibrium state: ≤2min;
8. The test cabin is equipped with multiple safety protections in terms of active protection and passive protection to avoid safety accidents caused by hydrogen leakage from the fuel cell during the development process;
9. Pump-type explosion-proof hydrogen concentration monitoring system to monitor the hydrogen concentration in the cabin in real time;
10. Three-level alarm safety protection, linked and interlocked with the exhaust system and test bench
11. Communication coupling and interactive control with the test bench control system;
12. Integrated structure and overall transportation save time on site installation and debugging;
