SYSTEM AND METHOD FOR CONTROLLING FUEL CELL

Disclosed is a fuel cell control system including: a fuel cell supplied with each of hydrogen and oxygen and configured to generate electric power by means of a chemical reaction therein; a cooling system having a heat-exchange device capable of exchanging heat with external air, the cooling system being configured such that cooling water circulates therein and exchanges heat with the fuel cell; a temperature sensing unit configured to sense a fuel cell temperature or a cooling water temperature in the cooling system; and a cooling control unit configured to control the cooling system so as to additionally cool the fuel cell when the fuel cell stops generating electric power, if the fuel cell temperature or the cooling water temperature sensed by the temperature sensing unit while the fuel cell generates electric power is equal to or higher than a preconfigured performance degradation temperature.
