Abstract: Disclosed herein is a method of controlling start/stop of a parallel fuel cell system, which, when controlling stop of a parallel fuel cell system in which two or more fuel cell systems are connected in parallel, considers operating state information of each fuel cell system, such as a current speed value of an air compressor and an opening degree of an air-exhaust-side air pressure valve of a fuel cell stack. Accordingly, the method can calculate a delay time for performing fuel cell system stop control for the two or more fuel cell systems, and sequentially perform the fuel cell system stop control for the two or more fuel cell systems based on the calculated delay time. Therefore, it is possible to minimize output delay of each fuel cell system and to achieve deterioration prevention and efficiency improvement of the fuel cell stack by fuel cell system start/stop control.
