SYSTEM AND METHOD FOR GENERATING ELECTRIC POWER WITH A FUEL CELL ARRAY, CONTROL UNIT AND DYNAMIC ELECTRICAL LOAD

Electric power is produced in a fuel cell array (120) based on chemical fuel (F) provided from a fuel source (110). The electric power is held available via an output terminal (125). A sensor cell (130) registers a sensor signal (Vs) reflecting a degree of consumption of chemical fuel (F) in the fuel cell array relative to an amount of chemical fuel (F) received in the fuel cell array (120). The production of electric power in the fuel cell array (120) is monitored by measuring at least one voltage (Vi, Vn, VOUT) in the fuel cell array (120). A fraction (PEF) of the electric power produced bythe fuel cell array (120) is controlled to be fed into a dynamic electric load (150) connected to the output terminal (125). The fraction (PEF) fed into the dynamic electric load ( 150) is controlledin response to the sensor signal (Vs) such that a difference is minimized between the amount of chemical fuel (F) received in the fuel cell array (120) and an amount of chemical fuel consumed in the fuel cell array (120) when
