| Zusammenfassung: | The present invention relates to an impedance measurement method of a vehicle fuel cell stack. More specifically, an object of the present invention is to provide an impedance measurement method of a vehicle fuel cell stack, capable of accurately measuring the impedance of a fuel cell stack during an operation of a vehicle. The impedance measurement method comprises: a first step of determining whether impedance measurement of the fuel cell stack is required; a second step of turning off a first relay; a third step of supplying air to the fuel cell stack; and a fourth step of measuring the impedance of the fuel cell stack.
