A method and system for managing energy of a fuel cell vehicle and a vehicle. The method is applied to a vehicle including a fuel cell, the vehicle further includes a power battery and a motor, the fuel cell and the power battery are electrically connected to the motor, and the method includes: acquiring a required power of the vehicle, a rated output power of the fuel cell and a current energy efficiency of the power battery; and according to at least one of the required power, the rated output power and the current energy efficiency, controlling the power battery to operate, and controlling the fuel cell to supply electric power at the rated output power or stop supplying electric power. In the present disclosure, not only the power battery can operate in the state of a reasonable energy efficiency to the largest extent, but also the fuel cell can always be in the two states of operating at the rated output power or of stopping operating, which prevents the problem that the fuel cell frequently operates at a non-rated output power, which results in a low economic efficiency of the hydrogen fuel and affects the economic efficiency of the entire vehicle.
