    摘要： The invention relates to a method for controlling a power assembly comprising a fuel cell unit and an electric energy storage system. The method comprises:
    - predicting (S1) a power demand for power delivery from the power assembly over a prediction horizon,
    - calculating (S2) costs associated with controlling the power assembly according to at least two different control scenarios during the prediction horizon, wherein the at least two different control scenarios include a first control scenario in which the fuel cell unit is turned off, and a second control scenario in which the fuel cell unit is turned on. For each of said control scenarios, the associated cost includes at least a cost associated with an expected ability or non-ability of the power assembly to deliver power according to the predicted power demand, a cost associated with fuel consumption, and a cost associated with fuel cell degradation,
    - comparing (S3) the calculated costs of the respective at least two control scenarios to obtain a comparison result,
    - selecting (S4) one of the at least two control scenarios based on the comparison result, and
    - controlling (S5) the power assembly according to the selected control scenario.

    摘要： The present disclosure relates to a system (20) for a vehicle (10), said system comprising at least a first fuel cell system (30) and a second fuel cell system (40), said first fuel cell system having at least one fuel cell (37) and a compressor (32) disposed in a cathode side of the first fuel cell system and arranged upstream the at least one fuel cell; wherein the first fuel cell system further comprises a controllable flow control valve (33) configured to direct compressed air to any one the at least one fuel cell and a separate fluid conduit (39) connectable to any one of a compressed air device and an exhaust outlet; said second fuel cell system having at least one corresponding fuel cell (47) and a corresponding compressor (42) disposed in a cathode side of the second fuel cell system and arranged upstream the at least one corresponding fuel cell; wherein the second fuel cell system further comprises a corresponding controllable flow control valve (43) configured to direct compressed air to any one the at least one corresponding fuel cell and a corresponding separate fluid conduit (49) connectable to any one of the compressed air device and the exhaust outlet.
