A protection system for a fuel cell is provided that has two different modes of operation. The protection system includes a fuel cell, a cooling system for the fuel cell that controls the temperature of the fuel cell responsive to a controller. The controller is operable in a first mode of operation when a time T for the next start-up is not known and a second mode of operation when the time T for the next start-up is known. In the first mode, a time Tis the time an estimated future ambient temperature is estimated to fall to near freezing wherein at Tthe cooling system purges the fuel cell. In the second mode, at Tthe cooling system turns on without starting the fuel cell. The controller turns of the cooling system when the fuel cell stack is warmed to a nominal temperature.
