SYSTEM AND METHOD FOR FUEL CELL LOAD CYCLING FOR FAST WARM-UP OF A FUEL CELL STACK

Power to a load in a fuel cell system is cycled between a high power level and a low power level. The cycled power levels are provided during a start-up phase of a fuel cell stack of the fuel system, such as during a cold start-up condition. During the high power level cycles, the power is delivered...

Zusammenfassung:	Power to a load in a fuel cell system is cycled between a high power level and a low power level. The cycled power levels are provided during a start-up phase of a fuel cell stack of the fuel system, such as during a cold start-up condition. During the high power level cycles, the power is delivered to a battery and/or other load, so that the battery is charged and/or the other load receives sufficient power during the start-up phase. During the low power level cycles, the battery can deliver power to the other load(s).
