The invention provides a power output method and device of a hydrogen hybrid electric vehicle, a medium and a vehicle, and belongs to the technical field of hydrogen hybrid electric vehicles. The method comprises the steps that the current SOC value of a power battery and the current whole vehicle demand power are obtained; weight coefficients corresponding to the current SOC value and the current whole vehicle demand power are obtained; and adjusting the weight of the current available power of the hydrogen fuel cell based on the weight coefficients corresponding to the current SOC value and the current required power of the whole vehicle, and outputting the current available power of the hydrogen fuel cell. According to the embodiment of the invention, on the basis of the current SOC value of the power battery, the current required power of the whole vehicle is comprehensively considered, and the output power of the hydrogen fuel battery can be adjusted to a proper position according to the actual demand of the whole vehicle, so that the hydrogen fuel battery can adapt to the variable dynamic power demand of the whole vehicle; and the requirements of the whole vehicle for the output capacity and the electric quantity of the power battery are reduced, and the vehicle cost and the operation and maintenance cost are reduced while the vehicle power requirement is met.
