An apparatus for controlling a fuel cell includes a cooling module that cools a fuel cell stack, a first temperature sensor that measures ambient air temperature of a vehicle, and a processor that, when a cooling fan of the cooling module is detected to be defective, determines a fail-safe control method depending on a defect situation of the cooling fan, sets a first limit level depending on the ambient air temperature, sets a second limit level depending on a state of charge (SOC) of a battery and an output requirement, and controls limitation of output of the fuel cell stack, based on at least one of the fail-safe control method, the first limit level, or the second limit level.

Apparatus and method for controlling fuel cell

An engine control method for a vehicle may include a temperature securing determination step of determining, by a controller, whether an exhaust gas temperature before a turbine of a turbocharger is normally secured; a basic determination step of, when the exhaust gas temperature before the turbine is normally secured, obtaining, by the controller, a first compensation torque according to a current state of the vehicle from a first compensation torque map according to the exhaust gas temperature before the turbine, an engine operation mode, engine speed, and atmospheric pressure; and an engine control step of, when the exhaust gas temperature before the turbine is normally secured, determining, by the controller, a final compensation torque on the basis of the first compensation torque and controlling engine torque at a value which is obtained by subtracting the final compensation torque from engine full-load torque.
