Abstract
A method for controlling a fuel cell system includes steps of: (a) determining whether hydrogen (H) is detected in an interior space of a stack enclosure in which a fuel cell stack is accommodated; (b) stopping power generation that is performed using the stack when it is determined in step (a) that the hydrogen is detected; (c) opening a purge valve to discharge gases circulating in an anode through the purge valve, and opening a condensate discharge valve to discharge condensate contained in a water trap through the condensate discharge valve; and (d) determining whether the hydrogen discharged through at least one of the purge valve and the condensate discharge valve in step (c) flows back to the interior space based on Hconcentration in the interior space.
