Modeling and Analysis of Hybrid Fuel Cell Systems for Vehicular Applications

Modelling and analysis of a hybrid system of fuel cell, battery, and ultra capacitor for vehicle propulsion is presented in this paper. All the components are modelled individually using practical results. A new control strategy is designed to obtain the high performance and better energy efficiency. A new model for PEM fuel cell is used to size the fuel cell, ultracapacitor and battery and study their performances. Simulation of the system is performed using MATLAB/SIMULINK and the results are presented
