Abstract

A method of controlling a fuel cell system includes decelerating the air blower that stops power generation of a fuel cell stack or supplies air to the fuel cell stack. A connection state of pipes connected to a valve is controlled by adjusting the valve disposed between an exit side of the air blower and an entrance side of a cathode of the fuel cell stack. According to the present disclosure, the time of maintaining open circuit voltage (OCV) can be reduced, and the dry out of the fuel cell stack can be prevented to improve durability of the fuel cell.
