Modeling and Simulation

The further improvement of performance, durability and cost of fuel cells and batteries requires a detailed understanding of the fundamental physical, chemical, and fluid mechanical processes occurring within the cell. In the Modeling and Simulation Group, multi-scale and multi-physics models as well as modern numerical simulation methods are developed and applied. Our particular expertise is in the areas of detailed electrochemical kinetics and electrochemical impedance spectroscopy. The activities are dedicated to solid oxide fuel cells (SOFC), polymer electrolyte fuel cells (PEFC), as well as lithium-ion and lithium-metal batteries (LIB).

 

• Model-based interpretation of experimental observations.
A detailed interpretation allows to push forward our fundamental understanding of the cell behavior.

• Model-based optimization of design, performance and lifetime
Comprehensive simulations support the development of fuel cells and batteries.

The activities are being carried out by around ten scientists in an interdisciplinary team. We closely collaborate with experimental groups of the Institute. Publication and dissemination activities create a high national and international visibility.
