Abstract
A condensate water drain control system for a fuel cell includes; a fuel cell stack configured to generate electric power through a chemical reaction of fuel, a fuel supply line configured to recirculate fuel drained from the fuel cell stack or supply fuel supplied from a fuel tank to the fuel cell stack, a water trap provided at the fuel supply line and configured to store condensate water generated in the fuel cell stack, a drain valve provided at an outlet of the water trap and configured to be opened or closed to allow or block drainage of the condensate water stored in the water trap, and a controller configured to control the drain valve to be closed on the basis of a state of supplying fuel to the fuel cell stack through the fuel supply line in a state of the drain valve is opened.
