Abstract: Presented are direct-current fast charger (DCFC) systems for fuel cell vehicles, methods for making/using such systems, and electric-drive vehicles equipped with fuel cell systems (FCS) and on-board DCFC systems. An on-board DCFC system mounts to a host vehicle and includes an electrical connector that electrically couples the host vehicle’s FCS system to multiple distinct transferee vehicles. A high-voltage (HV) distribution unit contains an HV bus circuit that electrically connects to the host vehicle’s FCS system and electrified powertrain. A DC-to-DC converter is electrically connected to the HV bus circuit to thereby receive an output voltage from the FCS via the HV distribution unit. The DC-to-DC converter modulates the FCS voltage to a recharge voltage of a transferee vehicle.
