An apparatus for generating injection current for a fuel cell stack includes a switch configured to retain any one state of an on state and an off state; an inductor configured to output accumulated energy according to a state of the switch; and a converter configured to provide an output of the inductor to a load or convert the output into a predetermined voltage and provide the predetermined voltage to a load.

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

An apparatus for generating injection current for a fuel cell stack includes a first converter configured to convert direct current of a voltage corresponding to a high voltage battery, into direct current of a predetermined voltage; a second converter configured to convert the converted direct current into alternating current; a filter configured to filter a signal of a predetermined frequency band from the converted alternating current; and a control unit configured to perform a feedback control to allow the filtered alternating current to be injected without being distorted when injecting the filtered alternating current into the fuel cell stack.
