Abstract
A fuel cell system includes a fuel cell stack configured to include a cathode and an anode, an air supplier configured to supply air to the cathode, and an air intake pipe configured to connect an outlet of the air supplier and an inlet of the cathode to each other and having an opening adjustable valve provided thereto. A controller is configured to adjust an opening of the valve according to a supplied amount of air to control a flow rate of air supplied to the cathode. Thereby, the fuel cell stack is prevented from drying-out, and durability of a fuel cell is improved.
