본 발명에 따른 연료전지 스택의 전압 제어 방법은, (a) 기준 시점에서 평가된 연료전지 스택의 성능인 기준 성능과, 기준 시점 이후의 소정 시점에서 평가된 연료전지 스택의 성능인 평가 성능에 기초해서 상기 연료전지 스택의 성능이 저하되었는지를 판단하는 단계, 및 (b) 상기 연료전지 스택의 성능이 저하된 것으로 판단되면, 상기 연료전지 스택의 전압 제어를 위해 최대 허용 전압으로서 설정되는 기준 전압을 이미 설정되어 있는 기존의 기준 전압보다 낮게 설정하는 단계를 포함한다.

    A voltage control method for a fuel cell stack is provided. The method includes determining whether a performance of the fuel cell stack is degraded based on a reference performance that corresponds to the performance of the fuel cell stack evaluated at a reference time point and an evaluated performance that corresponds to the performance of the fuel cell stack evaluated at a predetermined time point after the reference time point. Additionally, the method includes setting a reference voltage, which is set as a maximum allowable voltage for adjusting a voltage of the fuel cell stack, to be less than an existing reference voltage in response to determining that the performance of the fuel cell stack is degraded.
