Measuring device for spatially-resolved material characterisation of PEM – MEA
Device for carrying out 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 4bar 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/cm³
Water-cooled flow fields with a very low temperature gradient compared to the unit under test.
