摘要:
Methods for starting a fuel cell system are provided. In one embodiment, the method includes providing hydrogen to an inlet of an anode of the fuel cell pressurizing the anode to a pressure; determining whether a blocked cell condition exists; if a blocked cell condition exists, if no blocked cell condition exists, initiating a normal start sequence, alternately reducing the pressure of the anode and increasing the pressure of the anode until an exit condition exists, the exit condition selected from a voltage of the fuel cell being stable, or a temperature of the fuel cell being greater than about 0° C., or both, and when the exit condition exists, initiating the normal start sequence.
