1. An apparatus for controlling a fuel cell, the apparatus comprising:
a cooling module configured to cool a fuel cell stack, wherein the cooling module includes a first cooling fan and a second cooling fan;
a first temperature sensor configured to measure an ambient air temperature of a vehicle; and
a processor configured to, when a defect of the first cooling fan or the second cooling fan is detected, determine a fail-safe control method depending on a defect situation of the first cooling fan or the second cooling fan, set a first limit level depending on the ambient air temperature, set a second limit level depending on a state of charge (SOC) of a battery and an output requirement, and control 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;
wherein when determining the fail-safe control method, the processor differentiates the control method depending on whether one or both cooling fans of the first cooling fan and the second cooling fan have failed, and differently executes the control of output of the fuel cell stack, a normally-operating fan, a torque of a drive motor, and operation of an indoor air conditioner.
