Fraunhofer-Institut für Mikrostruktur von Werkstoffen und Systemen IMWSFraunhofer 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)
