Simplified electrical model tuned for actual controlled PEMFC

Using fuel cells in combination with other sources as energy elements in transport application is now a reality. Having, at least, two power sources on board, requires an efficient energy management strategy. Most of these energy management strategies are model-based. In order to reduce computation time consumption for such a global simulator, simplified models must be established. Such a simplified physical fuel cell model is thus proposed in this work. A complete model is studied in simulation to derive a simpler model tuned not only with the simulator parameters but also with parameters identification made on an actual fuel cell. Results obtained on current and voltage behaviors, following an actual requested power demand, are accurate enough to use the proposed model in iterative optimization algorithms
