    摘要: A hydrogen storage system may include a storage container storing liquid hydrogen, a supply line connected to the storage container and to a fuel cell system, the supply line supplying gaseous hydrogen to the fuel cell system from the storage container, a compressor mounted in the supply line and compressing the gaseous hydrogen, a bypass line connecting the supply line and the storage container and allowing the gaseous hydrogen to flow from the supply line to the storage container, a control valve mounted in the bypass line and selectively adjusting a bypass flow rate of the gaseous hydrogen, an orifice provided in the bypass line, and a controller configured to control the control valve, accurately adjusting a supply pressure of the storage container and a supply amount of the hydrogen to be supplied to the fuel cell system based on the operation conditions of the fuel cell system.

    摘要: A solenoid valve is provided to control a gas supply pressure such as a hydrogen supply valve of a fuel cell system. In particular, the solenoid valve includes: a valve body including a nozzle and a valve chamber, a nozzle opening/closing sheet, and a gas bypass hole formed on the valve body to communicate with a valve chamber of the valve body when the nozzle is closed and supply gas to a first chamber of the valve chamber through the gas bypass hole. With this arrangement, the solenoid valve may inhibit gas leak that can occur in the nozzle due to a diameter error of the nozzle due to a production deviation and a production deviation of a regulator.

    摘要: A pressure regulator for a fuel cell system may include: a housing having an inlet port into which gas is introduced, an outlet port through which gas is discharged, and an regulated pressure chamber connected to an outside through the outlet port; a piston moving up and down in the housing, having a main flow path penetrating through an inside of the housing and a pressure acting portion applying a pressure of gas in the regulated pressure chamber of the housing, and selectively communicating between the inlet port and the regulated pressure chamber of the housing through the main flow path as the piston moves up and down; and a spring provided in the housing to elastically support the pressure acting portion of the piston on an opposite side of the regulated pressure chamber.
