SYSTEM AND METHOD FOR CONTROLLING OPERATION OF FUEL CELL SYSTEM

A system and method for controlling operation of a fuel cell system, includes determining whether there is a risk of flooding by confirming whether the fuel cell system satisfies a predetermined flooding risk condition, and performing air supercharging by supplying air at a flow rate increased compared to an air supply demand to fuel cells of the fuel cell system, when the controller confirms that the fuel cell system satisfies the flooding risk condition.
