A method for generating an injection current of a fuel cell stack performed in an injection current generation device of a fuel cell stack according to an embodiment of the present invention, includes the steps of extracting a first frequency current and a second frequency current by allowing alternating currents corresponding to different frequency domains to pass through a plurality of filters respectively, wherein the alternating currents are generated by an alternating current generator; generating a synthesized frequency current by synthesizing the first frequency current and the second frequency current; and applying the synthesized frequency current to the fuel cell stack. Therefore, according to the present invention, the first frequency current and the second frequency current are extracted by allowing a synthesized current obtained by synthesizing currents of different frequency domains to pass through a plurality of filters for extracting specific frequencies respectively, and the first frequency current and the second frequency current are synthesized, so that a synthesized current free from a harmonic component is generated to be applied to the fuel cell stack. |
