Fuel cell power plants are complex, non‐linear systems. Their control is not yet sufficiently resolved. According to recent publications [1] and based on our own experience, with a demonstration plant, problems exist especially at plant start‐up and under dynamic operating conditions. In an ongoing project, optimal control concepts are developed with the main focus on plant start‐up. The first part of this paper describes the demonstration plant and depicts the present problems. The second part describes the plant model, which was derived based on physical and chemical laws. It is the basis for control system design and optimisation. The third part covers the start‐up process and its optimisation. Our project partners are the Department for Energy Conversion and Storage of the University of Ulm and the Centre for Solar Energy and Hydrogen Research Baden‐Württemberg (ZSW).
