Method for generating injected current of fuel cell stack and apparatus performing the same

Abstract

Disclosed herein is a method for generating an injected current of a fuel cell stack performed in an apparatus for generating an injected current of a fuel cell stack, the method including: extracting a first frequency current and a second frequency current by passing alternating currents of different frequencies through a plurality of filters, respectively; generating a summed frequency current by summing the first frequency current and the second frequency current; and applying the summed frequency current to the fuel cell stack. Therefore, it is possible to operate the fuel cell stack by applying the summed current obtained by summing the alternating current for calculating the total harmonic distortion (THD) and the alternating current for calculating the impedance to the fuel cell stack.
