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.

Claim (Index 17):
The apparatus of  claim 12 , wherein the vehicle controller is configured to compare a hydrogen tank pressure confirmed and stored at the time of key-off of the vehicle and the hydrogen tank pressure before performing secondary wakeup and when the pressures are equal to each other, determine the leakage generation in the hydrogen tank.
