Fuel Cell Dual-mode Train: Impact of Charge Depleting Strategy on Hydrogen Consumption

The charge-sustaining strategy is usually studied for a hybrid diesel-electric train. Due to the high price of hydrogen and the reduced autonomy compared to a diesel-electric train, this option is not ideal for a fuel cell dual mode train. The purpose of this paper is to investigate a charge-depleting strategy. In order to reduce hydrogen consumption, the batteries are discharged in non-electrified lines and recharged via the overhead line, when the train is running or in stations. Compared with a charge-sustaining strategy, simulation results show a hydrogen consumption reduction of 17.55%.
