Beschreibung
Zusammenfassung:	An apparatus for measuring average power of a fuel cell may include: a voltage measurement unit configured to sequentially measure forward voltages of unit cells including a fuel cell stack from a bottom cell to a top cell, and sequentially measure reverse voltages of the unit cells from the top cell to the bottom cell; a current measurement unit configured to measure a current of an output terminal of the fuel cell stack; and a control unit configured to control the voltage measurement unit to measure the reverse voltages based on a current measurement time point, after the voltage measurement unit measures the forward voltages, and calculate average power using the forward voltages, the reverse voltages and the measured current.
