Warming feature for aircraft fuel cells

A system (10) and method for warming a fuel cell (20) on an aircraft, the system includes at least one fuel cell (20). The fuel cell (20) includes an anode and a cathode for creating thermal and electrical energy. A temperature sensor (44) measures a first temperature of the fuel cell (20). A control unit (50) is coupled to the temperature sensor (44). The control unit (50) increases the first temperature to a second temperature in response to the first temperature being at least equal to a selected temperature threshold. Increasing of the first temperature is indicative of the control unit (50) operating in a warming mode. The second temperature is higher than the selected temperature threshold.
