Abstract
Operating points of a fuel cell system (FCS) can be shifted to its high-efficiency region by hybridization in a fuel cell hybrid vehicle (FCHV), so the hydrogen can be saved. In this paper, the hydrogen consumption of an FCHV is compared to that of a fuel cell vehicle (FCV). A power management strategy is applied to the FCHV and the related simulation is carried out. The concept of equivalent hydrogen consumption is introduced in order to consider the effect of the difference between initial and final battery SOC on the total hydrogen consumption.
