A hybrid fuel cell system includes a fuel supply system including a fuel tank, a start-up subsystem, a reforming subsystem and a depressurization system. The reforming subsystem is to receive fuel and to reform fuel to generate a hydrogen enriched gases and steam mixture. The hybrid fuel cell system includes a water supply system that provides water for the steam generator. The water supply system includes a water condenser directly downstream from the reforming subsystem that is in fluid communication with the hydrogen enriched gases and steam mixture to condense the hydrogen enriched gases and steam mixture into water and hydrogen enriched gases. The depressurization system is to reduce a pressure of the hydrogen enriched gases. The hybrid fuel cell system includes a fuel cell stack downstream from the depressurization system and having an anode inlet in fluid communication with the depressurization system to receive the hydrogen enriched gases.
