Abstract
An insulation resistance detection apparatus includes a processor configured to separate a fuel cell from a high voltage battery depending on an insulation resistance value of a vehicle during driving of the vehicle, and then to measure an insulation resistance value of the fuel cell to determine whether it is a failure of the fuel cell or a failure of the high voltage battery, and when it is the failure of the fuel cell, to determine a cause of the failure by calculating an insulation resistance variation; and a storage configured to store data and algorithms driven by the processor.
