Method and facility
In our team we have a variety of methods and equipment for the development and characterization of new catalyst materials.
The focuses of our research team are on the development of electro-catalysts and their applications in CO2 and H2O electrolysis and fuel cells based on solid electrolyte membrane. Particularly, we are aiming to develop advanced electro-catalysts based on noble and non-noble metals as well as alloys. Additionally, the design and optimization of catalyst layers (electrodes), based on advanced catalysts is a focus. The general aims are to improve energy efficiency and significantly reduce precious metal usage and thus the costs of fuel cell and electrolysis systems. In addition, we research and design catalysts for novel electrochemical reactor systems for the synthesis of energy carrier molecules.
Our research group work on the following topics:
