A fuel cell power plant keeps track, such as with a fuel-off timer (41), of the extent to which shutdown of the fuel cell power plant has occurred, in case the fuel cell power plant is quickly commanded to resume full operation. In one embodiment, if the fuel-off timer has not timed out at the time that the fuel cell power plant is ordered to resume full operation, a fuel-on timer is set (51) equal to the value of the fuel-off timer when the fuel cell power plant is ordered to resume full operation. Then, the fuel cell power plant is refueled (22), in a duration of time related to the setting of the fuel-off timer, rather than doing a full fuel purge.
