The invention discloses a power-off continuous hydrogen leakage monitoring system for a fuel cell commercial vehicle, which comprises a switching circuit module, a hydrogen leakage controller and a hydrogen leakage storage battery, the hydrogen leakage controller is used for carrying out abnormal judgment on hydrogen leakage according to detection information detected by the vehicle-mounted detection equipment related to hydrogen leakage monitoring and sending an instruction to controlled equipment related to hydrogen leakage monitoring; the hydrogen leakage storage battery is used for supplying power to vehicle-mounted electric equipment related to hydrogen leakage monitoring, the output voltage of the hydrogen leakage storage battery is smaller than the output voltage of the whole vehicle storage battery, and after the fuel cell commercial vehicle is powered off, the vehicle-mounted electric equipment related to hydrogen leakage monitoring is connected with the hydrogen leakage controller through the switching circuit module. The vehicle-mounted electric equipment related to hydrogen leakage monitoring is connected with the hydrogen leakage storage battery through the switching circuit module. The problem that the hydrogen leakage condition is not detected during hydrogen charging or long-time parking is solved, and the energy consumption is low.
