Test bench for measuring material parameters such as permeation, diffusion and sorption under a hydrogen atmosphere
Test bench for measuring material parameters (permeation, diffusion and sorption) across a large temperature and pressure range. The test gas is applied to the test specimen in a special tensioner assembly and the targeted metrics can be determined via changes in pressure.
Test medium
Hydrogen
Temperature range
-70°C to +180°C in temperature chamber
Pressure range
Max. 875bar H2
Special features
Tensioner with special sealing and pressure technology for test items with a measuring area of 50cm²
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 boundaries (e.g. 25mm x 16mm)
Current density up to 10A/cm²
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
