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. At the Computational Electrochemistry, 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).
