In all the above electrolysis technologies we focus on the following areas of work:

  • Optimisation of the specific energy demand and expansion of the operating window
    • Design of electrodes
    • Design of membrane electrode assemblies (MEAs)
    • Multi-phase material transport in porous layers and channels
  • Optimisation of the purity of product gases
  • In-situ and operando characterisation of the ageing conduct of MEAs
  • Diagnosis
  • Operation management/regulation, incl. dynamic operational management concepts
  • Conceptional design of water electrolysis systems and optimisation of the total energy demand
  • Lifecycle analysis and business model evaluation/development
  • Feasibility studies, potential studies and economic feasibility studies
  • System integration and process optimisation

We apply the following methods:

  • Experimental characterisation of single cells, short and full stacks:
    • Polarisation conduct
    • Electrochemical impedance spectroscopy
    • Gas purities and gas composition
    • Current density distribution in spatially extended cells
    • Long-term measurements and accelerated ageing tests
  • Physical characterisation
    • Pore size distribution
    • BET surface
    • Density
    • Topography, electrical and ionic conductivity
    • Clarification of structure with microscopic and spectroscopic methods
  • Modelling/Simulation of the underlying physico-chemical processes
  • Process simulation
  • Application of mathematical optimisation processes
