The present disclosure provides a method of managing thermal loads in a fuel cell electric vehicle. The method may include measuring a coolant temperature at an outlet of a fuel cell radiator, calculating a fuel cell coolant flow value, calculating a fuel cell heat generation value, calculating a feedback portion of a fuel cell radiator fan speed command using the coolant temperature at the outlet of the fuel cell radiator, calculating a feedforward portion of the fuel cell radiator fan speed command using an ambient temperature, the fuel cell coolant flow value, and the fuel cell heat generation value calculating the fuel cell radiator fan speed command using the feedforward portion and the feedback portion, and controlling a fuel cell radiator fan speed using the fuel cell radiator fan speed command.
