The present invention relates to a control method of the operating pressure of a fuel cell system. More specifically, the present invention relates to a control method of the operating pressure of a fuel cell system, which allows the operating pressure of the fuel cell system to be easily and variably controlled by integrating a compressor and an outlet pressure control valve in a pressurized fuel cell system; and controlling the compressor and the outlet pressure control valve to be interlocked. In other words, the present invention provides a control method of the operating pressure of a fuel cell system, which allows the operating pressure of the fuel cell system to be easily and variably controlled by integrating an air compressor controller and an outlet pressure control valve controller into one; and controlling the rotation number of an air compressor and the opening of an outlet pressure control valve to be interlocked, instead of controlling operations of the compressor and the outlet pressure control valve by receiving feedback on the measurement value of a pressure sensor like an existing fuel cell system. |
