摘要： A system and method for limiting voltage cycling of a fuel cell stack during a stand-by mode by providing power from a battery to the stack while the stack is turned off. The method includes monitoring the voltage of each of the fuel cells in the fuel cell stack and determining an average cell voltage of the fuel cells in the fuel cell stack. The method also determines whether the average cell voltage of the fuel cells in the fuel cell stack has fallen below a predetermined voltage value and, if so, applies a voltage potential to the fuel cell stack to increase the average cell voltage above the predetermined voltage value.

摘要： A method for reducing the probability of an air/hydrogen front in a fuel cell stack is disclosed that includes closing anode valves for an anode side of the fuel cell stack to permit a desired quantity of hydrogen to be left in the anode side upon shutdown and determining a schedule to inject hydrogen during the time the fuel cell stack is shutdown. The pressure on an anode input line is determined and a discrete amount of hydrogen is injected into the anode side of the stack according to the determined schedule by opening anode input line valves based on the determined pressure along the anode input line so as to inject the hydrogen into the anode side of the stack.

摘要： A method for reconditioning a fuel cell stack. The method includes determining whether fuel cell stack reconditioning is desired based on predetermined reconditioning triggers, determining if predetermined system constraints are met that will allow reconditioning of the fuel cell stack to occur, and determining whether previous reconditioning processes have been attempted, and if so, whether predetermine reconditioning limits have been exceeded during those attempts. The reconditioning process is initiated if one or more of the reconditioning triggers has occurred, the predetermined system constraints are met and the predetermined reconditioning limits have not been exceeded. The reconditioning process increases the humidification level of a cathode side of the fuel cell stack over the humidity level of the cathode side during normal operating conditions and waiting for cell membranes in the fuel cell stack to saturate after the humidification level of the cathode has increased.

摘要： A method for reconditioning a fuel cell stack. The method includes periodically increasing the relative humidity level of the cathode input airflow to the stack to saturate the cell membrane electrode assemblies to be greater than the relative humidity levels during normal stack operating conditions. The method also includes providing hydrogen to the anode side of the fuel cell stack at system shut down while the membrane electrode assemblies are saturated without stack loads being applied so that the hydrogen crosses the cell membranes to the cathode side and reacts with oxygen to reduce stack contaminants.
