The modeling of electrochemical systems is a multiscale problem. While the charge transfer at the electrode/electrolyte interface takes place on an atomic scale, system modeling requires highly simplified submodels for the system components that allow real-time simulation of the system operation.

In the lecture, current electrochemical models for batteries and fuel cells are presented at the different levels, the experimental determination of the model parameters is discussed and examples of model validation are shown.

In the lecture, participants are introduced to the fundamentals of electrochemical modeling using selected examples from the research areas of batteries and fuel cells.
