Testing system for pre-assembly as well as testing of series components in fuel cell systems
The following functions of a series component are tested via the testing system: valve function, pressure test, gross leakage test, internal and external leakage test with helium, temperature sensors, heating function, determination of the Kv value, pressure reduction.
Test media
Compressed air, helium
Special features
Testing of series components
Helium leak test under vacuum up to 1E‾⁶mbar*l/s
Test bench with assembly area and testing system
Leak testing system for production level fuel cell systems
The four units of a fuel cell system (e.g. the air treatment unit, anode assembly, water circuit and fuel cell system (anode, cathode) can be tested for leaks using this system.
Test medium
Compressed air
Special features
Testing of different series assemblies
Quick and easy connection of the test item
Interface to the production line
Gas metering valve test bench for functional and series testing
Test bench for functional testing and series testing of gas metering components using non-flammable gases.
Test media
Compressed air, nitrogen
Special features
Series component testing
Automated leak detection system
The test system is used to determine the helium leakage rate on a water separator equipped with an integrated heating valve. For this purpose, the test item is integrated into the system, covered with a hood and pressurised with helium.
Test medium
Helium
Special features
Series component testing
Measuring device for spatially-resolved material characterisation of PEM – MEA
Device for measurements and optimisations on PEM membranes and their components such as GDL. The non-destructive measurement of small areas of a membrane can be carried out freely on any size membrane / GDL at pressures up to 4 bar and temperatures up to 90°C without the need for any additional provisions. Areas of application for this device are development, production and damage analysis.
Application
Equipment used for the material characterisation of small parts of a membrane electrode unit and its components under real process conditions
Special features
Defined balance area
(e.g. 25mm x 16mm)
Current density up to 10A/cm³
Water-cooled flow fields with a very low temperature gradient to the unit under test.
Integration of the measuring device into the test bench as with “normal” fuel cells
Funding by ZIM and BMWi
Patent application
Test module for a pneumatic workstation
Function and leak tests with compressed air can be carried out on the pneumatic workstation module.
Test medium
Compressed air
Special features
up to 18bar
