The invention relates to a hydrogen fuel cell energy control method and device and a vehicle, and the method comprises the steps that the instantaneous demand power in the current time period and the actual instantaneous output power of a hydrogen fuel cell system are obtained, and the instantaneous demand power is the whole vehicle instantaneous demand power or the motor instantaneous demand power; according to the instantaneous demand power and the actual instantaneous output power, determining the sum of demand power in the current time period and the sum of actual output power of the hydrogen fuel cell system; determining the ratio of the sum of the required power to the sum of the actual output power; and controlling the output power of the hydrogen fuel cell system according to the ratio. And the output power of the hydrogen fuel cell system is adjusted according to the sum of the instantaneous required power and the sum of the actual output power, so that the problem of frequent load change of the hydrogen fuel cell due to the fact that the output power of the hydrogen fuel cell system is dominated by the power demand of the whole vehicle to change is solved, and the health state of the hydrogen fuel cell is improved.
