// Gas diffusion layers and microporous structures

We are specialised in investigating gas diffusion layers (GDLs) and microporous structures. A variety of methods and processes are available for this. For in-depth information on the individual methods, please read the enclosed PDFs:

Water balance

  • In-situ with X-rays with synchrotron or µ-computer tomography and ex-situ investigations (Leverett function)
  • Contact angle measurements:
    (Drop contour, liquid sorption measurements, inverse gas chromatography)
  • Hydro head
  • Bubble point
  • Vapour sorption

Mechanical and electrical characterisation

  • X-ray microcomputer tomography
  • Tension/compression testing machine
  • Bending stiffness
  • Geometric tests and CAD matching (white light interferometer and X-ray µ-computer tomography)
