Abstract
A fuel cell system includes a fuel cell stack including a cathode to which air is supplied, and an anode to which hydrogen is supplied. In particular, the fuel cell system further includes: an air discharge line to discharge the air discharged from the fuel cell stack into the atmosphere; a pressure adjuster provided in the air discharge line to selectively open or close the air discharge line; a first hydrogen discharge line connected to the fuel cell stack and the air discharge line at an upstream side of the pressure adjuster; a second hydrogen discharge line connected to the first hydrogen discharge line and the air discharge line at a downstream side of the pressure adjuster; and a hydrogen discharge valve part to selectively open or close at least one of the first hydrogen discharge line or the second hydrogen discharge line based on a pressure of the anode.
