Abstract
Proposed are a fuel cell system and a method of controlling the fuel cell system. The fuel cell system may comprise a discharge valve configured to adjust a flow rate between an inlet and an outlet, connected at the inlet to a water trap connected to an anode of a fuel cell stack, and connected at the outlet to an external exhaust line, and a controller configured to derive an error value on the basis of a difference between condensate water production amount and discharge amount of the anode of the fuel cell stack when the discharge valve is in an open state, configured to correct the condensate water production amount of the anode on the basis of the error value when the discharge valve is in a closed state, and configured to open the discharge valve when the corrected condensate water production amount exceeds a predetermined first reference value.
