This paper is intended to give an overview of current and future research activities of the Institute of Aircraft Systems Engineering in the field of model-based systems architecting and control systems development for multi-functional fuel cell systems (MFFCSs). The complexity of the system’s architecture is what makes both of these tasks so challenging. To efficiently handle this complexity in terms of systems architecting, a model-based methodology for the development and assessment of multi-functional fuel cell system architectures is being introduced. It is based on a system design method, which covers all stages of the system design process. Taking the required functions at aircraft level into account, it results in entirely sized fuel cell system architecture. Finally, this architecture’s performance is assessed based on reference flight missions. The developed procedure makes use of so-called behavior models, which own the property of being self-sizing. The system architecture complexity is reflected in the complexity of the required control system. Thus, the corresponding design process is subdivided into several steps and is directed towards the implementation of a hierarchical concept. This concept is based on a supervisory application, which controls several system applications. The utilized development approach supports the systematic design of this hierarchical concept and is capable of integrating related requirements. A virtual integration
