This paper presents a Proton Exchange Membrane Fuel Cell model suitable for water management analysis. In order to be integrated into a complete fuel cell vehicle simulation for real-time control and energy management designs, Energetic Macroscopic Representation is used. An experimental validation is performed and electric and gaseous behaviors are studied in particular. The integration of the developed model into a vehicle simulation, in which the FC is used as a range extender, demonstrates the use of the model and allows the study of the behavior of this system.
