Fraunhofer IMWS offers outstanding equipment for water electrolysis, especially with regard to material diagnostics down to the level of the microstructure and electrochemical characterization.
Electrochemical characterization
- PEM electrolysis test bench up to 25 V, 150 A and 30 bar (Greenlight Innovation) – Single cells / short stack tests with individual cell monitoring
- Potentiostats from Gamry, Princeton Applied Research (up to 30 A)
- quickCONNECT test cell with liquid cooling and reference electrode
- Rotating disc electrodes (RDE) and rotating ring-disc electrodes (RRDE) for electrochemical material characterization
Microstructural analysis
- Various ion/electron microscopes (SEM, ESEM, TEM, STEM, EDX, WDX, EBSD, EELS, HAADF) as well as preparation techniques (FIB, microtomy (Ultra, Kryo), etc.)
- Radiographic and acoustic processes (XRD, lock-in thermography)
- Physical and chemical surface analytics (ToF-SIMS, XPS, UPS, AES, OES)
- Topography and contour measurement (AFM)
- Photo-optical and spectrometric procedures (light microscopes, UV/VIS/NIR, FTIR)
- Electrical characterization (4-point method)
- Thermophysical measurement procedures (differential calorimetry, thermogravimetry, dilatometer, heat conductivity measurement)
- Material and trace analysis (ICP-MS, density and porosity measurements, Karl Fischer titration)
