Abstract
A method is provided for controlling a hydrogen cut-off valve, which may be provided on a hydrogen supply line of a fuel cell system, in driving a fuel cell vehicle mounted with a hydrogen supply line including a high-pressure tank storing hydrogen, a hydrogen supply valve, and a hydrogen cut-off valve. The method includes: a step (a) of measuring a duty applying to the hydrogen supply valve and a step (b) of comparing the duty with a predetermined duty, in which when the duty is equal to or more than the predetermined duty, it is determined that the hydrogen supply line between the high-pressure tank and the hydrogen supply valve is abnormal.
