This paper presents the effect of regenerative braking on the hydrogen consumption of fuel cell electric vehicle (FCEV). The hydrogen consumption of Fuel Cell/Battery/Supercapacitor (FC/BATT/SC) electric vehicle is compared for regenerative braking and non regenerative braking (non-RB) cases. Frequency splitting operational state control strategy (FSOSCS) is used for the energy management of FC/BATT/SC configurations. Simulation is carried out in MATLAB/Simulink environment. The results indicate that use of regenerative braking causes improved battery state of charge (SOC level), increased voltage of supercapacitor, improved transient performance and reduced stress on fuel cell, thus resulting in reduced hydrogen consumption.
