SIMPLIFIED FUEL CELL SYSTEM MODEL IDENTIFICATION

The use of fuel cell and supercaps as energy elements in transport application is now a reality. Having two power sources on board allows a certain energy management strategy. In order to reduce computation time consumption, a simplified physical fuel cell model is proposed. An accurate model is studied in simulation to derive a simpler model. The simplified model is used with parameters identification made on an actual fuel cell. Results obtained on current and voltage, with an actual power demand, are sufficient to use the proposed model in iterative optimization algorithms.
