Fuel cell vehicles, (FCV) are characterized by the utilization on the same electric bus of an hydrogen fuel cell (FC) as a primary energy source and of storage elements like batteries as a secondary source. In our project, the fuel cell is a Polymer Electrolyte Membrane (PEM), which is well adapted for transport field applications. A Lithium rechargeable battery, more specifically a LiFePO4, is used to supplement the FC over the driving cycle. According to the requirements of the drive cycle of the vehicle, a 30 kW PEM FC system and a 4.5 kWh LiFePO4 battery is considered here. To define the power supplied by each source an energy management system is used.
