Abstract
A fuel cell system and a control method thereof include an air supply line supplying air to a fuel cell stack and an air discharge line discharging post-reaction air, a stack pressure sensor provided in the air supply line to measure pressure of air at an inlet side of the stack supplied to a cathode side of the fuel cell stack, an air cutoff valve provided with a bypass line connecting the air supply line and the air discharge line in the air cutoff valve, and a controller electrically connected to the stack pressure sensor and the air cutoff valve and configured to determine pressurization time and pressurization torque for the air cutoff valve when the controller concludes that it is necessary to shut off air inside a cathode and control the stack pressure sensor and the air cutoff valve according to the determined pressurization time and the determined pressurization torque so that inside of the cathode is airtight even after stopping of a fuel cell in the fuel cell stack is completed.
