Research

Our projects can be categorized into the following three subgroups:

  • New catalyst concepts
  • Functional electrode design
  • In-situ methods

These are used to study batteries, fuel cells, and also heterogeneous catalysis in general. For example, with X-ray absorption spectroscopy (XAS), we can analyze and understand the interactions of hydrogen and CO adsorbates on the platinum surface of the catalyst during real fuel cell operation. The ion beam tomography (FIB / SEM) allows us to calculate 3D reconstructions of the electrode structure. This is particularly useful when alternative materials with a new morphology are synthesized.
