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.
Stack and module test items:
Routine inspection, gas leakage test, normal operation test, hydrogen leakage test, freeze/thaw cycle test, high temperature storage test, air tightness test, dynamic test, power generation performance test, shutdown test, low temperature storage test, low temperature startup test, etc.
Technical advantages:
1. The intake plateau altitude simulation system and exhaust gas plateau altitude simulation system are set up to simulate the air pressure at the intake plateau altitude, the air pressure, temperature, and humidity at the exhaust plateau altitude for testing the hydrogen fuel engine system;
2. A front hydrogen precooler and an air precooler are added to ensure that the low-temperature cold start test of the hydrogen fuel cell stack can be completed. The front hydrogen precooler and the front air precooler adopt multi-channel PID fluid temperature control. Technology (this is existing technology), the temperature of the fluid can be constantly controlled to meet the test requirements under different flow rates;
3. A variety of safe and effective protective measures have been added for the special working environment of hydrogen, with good safety;
4. It is especially suitable for environmental testing of hydrogen fuel cell stack engine systems and can meet the requirements of test environments such as plateau altitude simulation and low-temperature cold start of hydrogen fuel cell stacks. It has great application prospects.
