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.

A parking cooler which is capable of battery powered operation during engine off operation. The parking cooler or air conditioning system may vary in cooling capacities to maximize cooling or maximize battery life. The parking cooler includes one or more condensers and a housing to accommodate such variation of cooling capacity.
