PURPOSE: An apparatus for generating a virtual sound source to monitor a cell operation state and a method thereof are provided to make a chord or sound changed by the state of a stack, thereby easily recognizing the operation state of a fuel cell stack. CONSTITUTION: A plurality of sensor units(102) detects the operation state of a fuel cell stack(100). A control device(104) selects the signals of the sensor unit as a chord or the signals as a specific sound. A sound generating device(106) generates the signal of each sensor as the chord or the selected specific sound. A user interface(108) controls the playing type and the size of the sound.
