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 14):
The apparatus of  claim 12 , wherein when hydrogen tank pressures before and after performing primary wakeup for injecting hydrogen gas which remains in a fuel supply line of a stack into a fuel cell stack by a pressure difference are equal to each other, the vehicle controller in configured to determine an excessive leakage generation in the hydrogen tank.
