Document Type and Number:
Japanese Patent JP5957186
Kind Code:
B2
Abstract:
The present invention provides a fuel control system and method, e.g., for a vehicle fuel cell system, which can efficiently supply hydrogen to a fuel cell stack and increase the efficiency of an ejector. For this purpose, the present invention provides a fuel control system having a series-connected multi-stage pressure control structure, in which an additional injector is provided in series between an injector for controlling the pressure of hydrogen supplied, a pressure control valve, or a pressure control actuator and a hydrogen recirculation ejector in a hydrogen supply passage, through which hydrogen is supplied from a hydrogen supply unit to a fuel cell stack, such that the pressure of hydrogen supplied is controlled in stages.
