Abstract

The invention discloses a fuel cell system without a high pressure line of a hydrogen supplying system. The fuel cell system includes a gas charging line formed between a gas charging station and a high pressure vessel charged with gas by the gas charging station, and a gas supplying line formed between the high pressure vessel and a stack, and also includes: a regulator provided in the gas supplying line, and a solenoid valve provided in the gas supplying line between the regulator and the high pressure vessel; and a check valve provided in a bypass line connecting one point of the gas supplying line between the regulator and the solenoid valve and one point of the gas charging line.

Description

technical field [0001] The present disclosure relates to a structure capable of minimizing high-pressure lines in a hydrogen supply system including a gas supply line and an inflation line in a fuel cell system-mountable vehicle. More specifically, the present disclosure relates to a fuel cell system and a control method thereof, in which a hydrogen supply system of the fuel cell system includes a regulator that can be provided on a gas supply line extending from a high-pressure container, a regulator that can be A solenoid valve between the high pressure vessel and the regulator and a check valve connecting the charge line to the gas supply line between the regulator and the solenoid valve. When the charging line is under high pressure, the check valve is opened, thereby eliminating the high pressure state of the charging line and the gas supply line between the regulator and the solenoid valve, thereby reducing the leakage that may occur in the hydrogen supply system of the ...
