Abstract:
An apparatus and method for measuring impedance of a fuel cell stack capable of accurately measuring the impedance even when a DC current of the fuel cell stack is changed depending on fluctuation of a load, by compensating for an AC voltage (or AC current) used to measure the impedance of the fuel cell stack based on a DC current of the fuel cell stack.
