The present invention relates to a fuel cell power generation system, capable of supplying a stable voltage when it is mounted on a vehicle and moves to a place requiring a power to supply an AC power converter and/or electric vehicle charging, and a control method thereof. According to the present invention, the voltage of an electricity supplied to a DC-AC power conversion unit and an electric vehicle charging apparatus may be maintained constant by using a high voltage battery capable of outputting a DC voltage higher than an output voltage of a fuel cell. In addition, the fuel cell power generation system of the present invention is controlled to avoid a low current density section while monitoring the voltage of the fuel cell. Therefore, durability can be improved. The fuel cell power generation system comprises: a fuel cell system; a DC-DC conversion unit; a high voltage divider; the DC-AC power conversion unit; an electric vehicle charging unit; the high voltage battery; and a control unit.
본 발명은 차량에 탑재되어 전력을 필요로 하는 장소로 이동하여 교류 전력변환기 및/또는 전기 자동차 충전을 공급할 때, 안정된 전압을 공급할 수 있는 연료전지 발전시스템 및 그 제어방법에 관한 것으로서, 연료전지의 출력 전압보다 높은 크기의 직류 전압을 출력할 수 있는 고전압 배터리를 이용하여 직류-교류 전력 변환부와 전기 자동차 충전장치에 공급되는 전기의 전압을 일정하게 유지할 수 있으며, 연료전지의 전압을 모니터링 하면서 저전류 밀도 구간을 회피하도록 제어하여 내구성을 향상시킬 수 있는 효과를 나타낼 수 있다.
