Processes and Components

About

Green hydrogen becomes competitive when produced and used efficiently on a large scale. Therefore, electrolyzers and other electrochemical devices need to be low cost, durable, and work efficiently with dynamic renewable energy sources. To achieve this, we need to understand and improve the function of all components in the cells. Especially the interaction between the components and with the operating conditions is important. New approaches and operating conditions offer new possibilities to make electrolysis more efficient, simple, and durable. This is why we work on understanding and optimizing these aspects in detail, with special focus on alkaline, PEM- and AEM-electrolysis.

Research Topics

  • New electrochemical processes at cell level.
  • Development of new components, also in collaboration with partners from reseach and industry.
  • Characterization of new components like electrodes, Separators, and transport layers in single cells.
  • Development of new characterization tools and special cell designs.
  • Stability, degradation, dynamic operation and accelerated degradation of electrochemical cells and components.
  • New modes of operation such as alternative water or electrolyte supply or increased temperature.
  • Understanding scaling effects from single cells to short stacks.
  • Coupling renewable energy sources with electrolysis.
  • Data analysis and use beyond present research questions
