摘要： An apparatus for diagnosing a state of a fuel cell stack is provided. The apparatus may diagnose the state of the fuel cell stack without including the DC-DC converter which boosts the DC voltage and the inverter which converts the boosted DC voltage into the AC voltage. In particular, the apparatus may diagnose the state of the fuel cell by applying the rectangular wave of the single frequency having a duty ration of about 0.5 to the fuel cell stack, measuring the voltage of the fuel cell stack, detecting the even multiple harmonic component of the frequency of the rectangular wave by performing the frequency conversion on the measured voltage, and then diagnosing the state of the fuel cell stack based on the magnitude of the detected harmonic component.

摘要： A system and method for diagnosing the state of a fuel cell stack are provided. The method includes simultaneously applying currents having respective first and second frequencies to a fuel cell stack and computing Fourier transforms of output currents and voltages from the fuel cell stack based on the applied currents. A real part of a first frequency impedance and an imaginary part of a second frequency impedance are calculated using amplitudes and phases of currents and voltages having the first frequency and the second frequency among the computed output currents and voltages. Further, a state of the fuel cell stack is determined by magnitude of the calculated real part of the first frequency impedance and by magnitude of the calculated imaginary part of the second frequency impedance.
