The invention discloses an electric-electric hybrid fuel cell vehicle energy management system which comprises a parameter acquisition module, a control module, a fuel cell, a power cell and a super capacitor. The parameter acquisition module is used for acquiring the required power of the whole vehicle, the SOC of the power cell, the maximum output power of the fuel cell, the minimum output power of the fuel cell and the optimal output power of the fuel cell; the control module is used for preferentially enabling the fuel cell to be matched with the required power of the whole vehicle when the SOC of the power cell is located in the first electric quantity area; when the SOC of the power cell is located in a second electric quantity area, the fuel cell is preferentially discharged at the highest discharge efficiency, and then the power battery is prevented from being discharged; when the SOC of the power cell is located in a third electric quantity area, the power cell is preferentially charged as soon as possible, the fuel cell outputs at the maximum output power, and the power battery and/or the super capacitor charges or discharges excessive power or insufficient power. The stability of the SOC of the power cell is guaranteed preferentially, the power generation efficiency of the fuel cell is guaranteed, and peak load shifting of energy of the whole vehicle is achieved.
