Fuel cell system idle speed control method, device, equipment and medium

The invention discloses a fuel cell system idle speed control method, device and equipment and a medium, and the method comprises the steps: obtaining a target parameter value of at least one operation parameter if the target demand power of a vehicle control unit for a fuel cell system is zero, and the at least one operation parameter is used for reflecting the working state of an electric pile; if the target parameter value of each operation parameter meets a preset condition, the fuel cell system is controlled to enter an idle speed zero power mode, and the preset condition is a parameter value range corresponding to each operation parameter when the working state of the electric pile supports the idle speed zero power mode. According to the technical scheme provided by the invention, the situation that after the fuel cell system enters the idling zero-power mode, the working state of the electric pile cannot support the idling zero-power mode operation, so that the electric pile fails, and the fuel cell s
