Modeling and Parameters Identification of PEM Fuel Cell for Application to a Hybrid Vehicle System

Abstract

In this chapter, we are interested in the study of instrumentation dedicated to the fuel cell especially that of the proton exchange membrane type PEM by measuring the complex impedance in order to anticipate the defects and avoid the severe problems of the stack such as the drowned or the reverse phenomenon. Thus, this work reviews the model description of the vehicle with a focus on architecture and modelling of the Powertrain. The power system of the fuel cell vehicle includes fuel cell system, DC/DC converter, the three phase inverter and the PM synchronous motor. Our Target is to minimize the hydrogen consumption of a Proton Exchange Membrane (PEM) Fuel Cell. In order to perform this goal, the system is controlled through an Energy Management Strategy (EMS), to minimize the fuel cell power demand transitions and therefore improves its durability. The proposed Energy management strategy is evaluated for the NEDC (New European Driving Cycle). The obtained results demonstrate the effectiveness of the proposed energy management strategy in reduction of the hydrogen consumption.
