Abstract
A perceiving method and system of a stack state for a fuel cell system is provided. The method includes determining whether a vehicle provided with the fuel cell system is started and calculating a time until first condensate water is discharged through a condensate water discharging valve provided in the fuel cell system after the vehicle starts. Then, an average time until the first condensate water is discharged after the vehicle starts, at the previous starting of the vehicle is calculated over a predetermined number of times. The two calculated times are compared to determine the state of the stack or cathode of the fuel cell system without requiring additional separate components.
