The invention relates to the technical field of hydrogen fuel cell vehicle energy management control, and provides a hydrogen fuel cell power control method and system, a vehicle and a storage medium, and the method comprises the steps: obtaining data of a road at a certain distance in front of the current vehicle through an ADAS map, and segmenting the data to obtain a plurality of predicted mileages; with hydrogen consumption as a target function and minimum hydrogen consumption in a global distance as a target, calculating an optimal path in a global range of the predicted mileage in a rolling manner based on a dynamic programming algorithm to obtain a target SOC; and controlling the power of the hydrogen fuel cell based on the target SOC. According to the method, the optimal path in the global range of the predicted mileage is calculated in a rolling manner based on the road data acquired through the ADAS map in cooperation with the DP algorithm, the target SOC of the corresponding predicted mileage segment is determined according to the optimal path with the lowest hydrogen consumption and is used for further controlling the power of the hydrogen fuel cell, the energy utilization rate of the cell can be effectively improved, and the energy utilization rate of the cell is improved. And meanwhile, the dynamic property and economical efficiency requirements of the vehicle are considered.
