Fuel Cell System Modeling and Control with Energetic Macroscopic Representation

This paper describes the application of Energetic Macroscopic Representation (EMR) to model complex multi domain devices like fuel cell systems. The basic elements of EMR and its inversion - the Maximum Control Structure (MCS) - are given and the advantages of this tool to evaluate model based control are pointed out. Than the application of EMR on fuel cell systems is demonstrated. Furthermore the application of EMR and selected aspects of MCS on a commercially available fuel cell system is shown. The simulation results show that EMR is a valid tool to describe fuel cell systems.
