According to an embodiment of the present invention, an apparatus for generating injected current for a fuel cell stack comprises: a first converter converting a direct current of voltage corresponding to a high voltage battery into a direct current of specific voltage; a second converter converting the converted direct current into an alternating current; a filter filtering a signal of predetermined frequency band from the converted alternating current; and a control unit controlling feedback so that the alternating current is injected without distortion when injecting the filtered alternating current into the fuel cell stack. Accordingly, the present invention uses the high voltage battery instead of a normal battery for vehicles, and can reduce a transformation ratio since it just needs to raise tens of volts when raising the voltage of the direct current of voltage corresponding to the high voltage battery, thereby reducing costs of components and the volume of a circuit. |
