The invention discloses an energy control method and device for a fuel cell vehicle, a vehicle and a storage medium, and the method comprises the steps that the charge state of a power battery in the fuel cell vehicle and the whole vehicle demand power are obtained, the fuel cell vehicle comprises the power battery and a fuel cell used for supplying power, the charge state of the power battery represents the residual capacity of the power battery, and the fuel cell represents the residual capacity of the fuel cell; the whole vehicle demand power represents the driving demand power of the fuel cell vehicle; determining a charge state threshold value of the power battery according to the required power of the whole vehicle; when the charge state is larger than a charge state threshold value, the power battery output power of the power battery is controlled to meet the whole vehicle demand power; and when the charge state is smaller than or equal to the charge state threshold value, the fuel cell is started, and the fuel cell output power of the fuel cell and the power cell output power are controlled to meet the whole vehicle demand power according to a preset energy distribution strategy. By the adoption of the energy control method, the problem that hydrogenation is inconvenient in the running process of the fuel cell vehicle can be solved.
