PURPOSE: A drain method for condensed water from a fuel cell in a slope way is provided to prevent condensed water from accumulating on one side and improve the durability of the fuel cell while maintaining the output of the fuel cell. CONSTITUTION: A drain method for condensed water from a fuel cell comprises a sensing step to sense the angle of the slope(S150); a step of determining whether the sensed slope angle can influence on the fuel cell(S200); and a step of draining the condensed water by increasing the operation of a hydrogen recirculation blower, according to the slope angle, when the sensed slope angle can influence on the fuel cell(S300). [Reference numerals] (AA) Start; (S100) Operate?; (S150) Detect the angle of a slope; (S20) Increase blower RPM; (S200) Does the angle of the slope influence on a fuel cell?; (S310) Calculate a blower scale factor; (S400) Calculate the required output of a vehicle; (S410) Is the increase of purge necessary for the required output?; (S460) Calculate a purge scale factor; (S470) Increase the cycle of the purge |
