The invention discloses a fuel cell vehicle energy management method and device, a vehicle and a storage medium. The method comprises the following steps: determining a vehicle running energy source at the current moment according to the state of charge of a power battery at the current moment in combination with the vehicle running energy source at the previous moment; determining the output real-time power of the fuel cell according to the vehicle running energy source at the current moment and the state of charge of the power cell at the current moment; acquiring driver demand power, and determining motor output power in combination with the fuel cell output real-time power, the available charging and discharging power of the power cell and the available power of the motor; controllingthe vehicle to run according to the motor output power, monitoring the state of charge of the power battery, and recording the change value of the state of charge of the power battery; and updating afuel cell output power calibration value according to the change value of the state of charge of the power cell. The variable load requirement of the fuel cell is reduced, overcharge and overdischargeof the power cell are prevented, the service life of the vehicle battery is prolonged, and the cost is saved.
