Project Description

The use of green hydrogen in electric vehicles by means of fuel cells is of great interest due to numerous advantages, such as the elimination of CO2 emissions, high efficiency, long range as well as possible fast refuelling. However, fuel cells are sensitive to the dynamic load cycles typical in vehicle applications, as these promote aging. The associated loss of performance and shortening of lifetime are among the major challenges in the development of fuel cell systems today.

In order to enable damage-free transient phases, model-based control concepts are designed in this project. High-resolution simulation models, real-time capable performance models as well as fuel cell test benches are used. This enables the identification of local damage-relevant operating conditions, the real-time capability of the developed control concepts as well as the validation based on measurement data.
