PURPOSE: A drain controlling method of condensed water in a water trap is provided to minimize a hydrogen exhaust except for the condensed water by the malfunction of a water level sensor inside the water trap. CONSTITUTION: A drain controlling method of condensed water in a water trap comprises the following steps: setting a current accumulation critical value, a current integrated value for maintaining a negative water balance, a maximum discharging valve opening time, and a reduction amount of the current accumulation critical value; performing a current accumulation and opening a discharging valve at the water trap; and closing the valve when passing the maximum discharging valve opening time or a when a water level sensor senses a dry state. |
