Fuel Cell Cooling Control System and Method

An embodiment fuel cell cooling control system including an inlet temperature sensor configured to detect a coolant inlet temperature including a temperature of a coolant supplied to a coolant inlet of a fuel cell stack, an outlet temperature sensor configured to detect a coolant outlet temperature including the temperature of the coolant discharged from a coolant outlet of the fuel cell stack, a pressure detector configured to detect a gas inlet pressure including a pressure of air supplied to a cathode-side inlet of the fuel cell stack, and a controller configured to estimate a reaction surface temperature in a cell of the fuel cell stack based on the coolant inlet temperature, the coolant outlet temperature, and the gas inlet pressure and to control a flow rate of the coolant supplied to the fuel cell stack according to the estimated reaction surface temperature.
