According to the present invention, a purge device includes: a purge valve connected to a discharge pipe discharging impurities reacting to hydrogen supplied to an anode of a fuel cell stack; and a control part controlling the opening and closing of the purge valve to discharge the impurities by controlling the purge valve when an accumulated flux of the impurities is greater than a preset threshold value, and increasing the concentration of the hydrogen supplied to the anode by determining a situation, in which the acceleration of a vehicle exceeds a standard acceleration, as a rapid acceleration, and then opening the purge valve. The device is capable of securing stable performance by increasing the concentration of hydrogen in the anode when the vehicle accelerates.

    본 발명에 따른 퍼지 장치는, 연료 전지 스택의 연료극으로 공급된 수소와 반응한 불순물이 배출되는 배출관에 연결된 퍼지 밸브; 상기 불순물의 누적 유량이 기 설정된 임계값보다 큰 경우 상기 퍼지 밸브를 제어하여 상기 불순물이 배출되도록 상기 퍼지 밸브의 개폐를 제어하고, 차량의 가속도가 기준 가속도를 초과하는 경우 급가속으로 판단하고 상기 퍼지 밸브를 개방하여 상기 연료극으로 공급되는 수소의 농도가 증가되도록 제어하는 제어부를 포함한다.
