This international research group focuses on the development of an ultra-compact, scalable, multifunctional membrane reactor system for efficient production of small amounts of hydrogen on-site and on-demand. This involves the investigation of new nanostructured catalysts as powder materials and coatings with improved activity and long-term stability as well as the study of novel supported palladium alloy membranes and the development of integrated devices using advanced microfabrication technology.

A Winter School of the Helmholtz-CAS Joint Research Group 118 on Integrated catalytic technologies for efficient hydrogen production was organized at the Environmental Research Station Schneefernerhaus (UFS) at Zugspitze. The School focused on the one hand on a scientific qualification program, consisting of lectures by KIT scientists, a colloquium on case examples referring to industrial establishment of compact chemical processes, excursions and round tours at two companies related to the group’s research objectives – Linde AG Engineering Division at Pullach and Clariant Produkte (Deutschland) GmbH at Bruckmühl-Heufeld – in order to provide direct insights into engineering aspects of industrial catalytic processes and industrial R&D and production of catalysts. On the other hand, the program was rounded off by a snowshoe walking group activity at the top of Germany’s highest mountain Zugspitze, which was fun for all participants. A detailed review of the school is available from the German and Chinese participants: German Review & Chinese Review.
