The invention discloses an integrated controller for a fuel cell system, and the input end of the integrated controller is connected to a fuel cell stack through a high-voltage wiring harness. The input end is connected with the output end of the integrated controller through an input EM I, a residual hydrogen discharging unit, an input pre-charging unit, an input capacitor, a DC/DC, an output capacitor, a PDU, an output pre-charging unit, an output fuse unit and an output EM I in sequence, the output end of the integrated controller is connected to a whole vehicle power system through a high-voltage wire harness, and the control system is connected with the DC/DC and sends a control instruction to the DC/DC. And the control system communicates with the integrated electric control main unit. According to the invention, a controller integrated function integration scheme is adopted, the cost of wire harnesses and part shells is saved, the volume power density of a fuel cell system is improved, and the function safety of the whole fuel cell vehicle is ensured through hybrid discharge strategy optimization.
