Abstract:
An apparatus and a method for detecting leakage in a hydrogen tank of a hydrogen fuel cell vehicle are provided. Particularly, leakage is detected due to failure of an airtight seal of a solenoid valve in a hydrogen tank based on a change of the sensing value of a high pressure sensor which represents a hydrogen tank pressure during a process of performing a wakeup operation at the time of key-off of a vehicle.
