AVAILABLE POWER OUTPUT DETERMINATION APPARATUS AND METHOD OF FUEL CELL STACK

An apparatus for determining available power output of a fuel cell stack may include a processor a memory. The apparatus may measure, in real-time during an operation of a fuel cell stack comprising a plurality of cells, a current value and a voltage value associated with the fuel cell stack; determine at least one parameter of the fuel cell stack by applying the measured current value and the measured voltage value to a current-voltage characteristic model; determine, based on applying the at least one parameter to the current-voltage characteristic model and based on an available voltage value of the fuel cell stack, an available power output of the fuel cell stack; and control, based on the available power output of the fuel cell stack, an operation of the fuel stack.
