Abstract
A hydrogen feed and recirculation device for a fuel cell system supplies hydrogen from a hydrogen tank and unreacted recirculated hydrogen discharged from a stack to the stack. The hydrogen feed and recirculation device can supply hydrogen to the stack through a first nozzle when hydrogen supply pressure is low and supply the hydrogen to the stack through a second nozzle using a Coanda Effect other than the first nozzle when the hydrogen supply pressure is high to satisfy a required hydrogen supply amount through an entire operating area of the fuel cell and prevent nozzle vibration and noise generation.
