Proton Exchange Membrane (PEM) Water Electrolysis

PEM water electrolysis could become a key component in future carbon free energy systems by providing sustainable hydrogen for large scale energy storage. In PEM water electrolyzers with a solid state proton conductive membrane, water is electrochemically split into oxygen and hydrogen. To improve the economic competitiveness of PEM electrolyzers, inter alia, developments in the fields of catalyst materials and membrane electrode assemblies (MEA) are necessary.

Our interests:

  • Characterization and optimization of membrane electrode assemblies (MEAs) with novel catalyst and membrane materials
  • Optimization of porous transport layers
  • Identification of aging mechanisms under transient operation conditions
  • Gas permeation measurements during high pressure electrolysis
