Hybrid Electric System for an Hydrogen Fuel Cell Vehicle and its Energy Management

International audienceFuel 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
