This paper explains the impacts of different fuel processor control strategies on the characteristics of a fuel cell vehicle. Emphasis is put on the impact of various fuel processor control strategies on the vehicle acceleration. The control algorithm will be qualitatively explained and the impact on the overall vehicle acceleration shown. The underlying vehicle characteristics as well as the characteristics of the individual vehicle components such as the electric drive train including transmission and the fuel cell system are modeled in a dynamic manner. Further the interaction between the individual components and a simple driver model is described. The algorithms are coded using the simulation tool Matlab/Simulink. The simulation tool is setup strictly in a modular form allowing modifications of individual component characteristics or control algorithms without the need to change the remainder of the model. To enable a more in depth discussion of the applied algorithms and the setup of the model this paper focuses solely on the case of an Indirect Methanol Fuel Cell Vehicle (IMFCV) with steam reformer and without any additional energy storage. Other papers expanding this initial work and discussing various cases of hybridization (batteries, ultra capacitors, reformate gas storages) are under preparation.The focus of the paper is on the explanation of the algorithms and not the calculation of vehicle properties associated with one specific vehicle design or technology.
