摘要： A fuel cell system includes: a supply flow path configured to supply reactant gas; a first branch flow path branching off from an outlet end of the supply flow path and configured to guide the reactant gas to a first fuel cell stack; a second branch flow path branching off from the outlet end of the supply flow path and configured to communicate with the first branch flow path and guide the reactant gas to a second fuel cell stack; and an inlet area change part disposed in a boundary zone between the first branch flow path and the second branch flow path and configured to selectively change inlet areas of the first and second branch flow paths. Efficiency in discharging condensate water is increased and performance and operational efficiency are improved.

摘要： An ejector has a variable nozzle structure and is installed in a fuel cell recirculation line to supply new hydrogen and a recirculation gas. The ejector includes: a first housing having a first hole through which hydrogen is supplied and an orifice through which the hydrogen is discharged; a second housing disposed in the first housing and having a second hole into which the hydrogen passing through the first hole flows; and a poppet penetrating a third hole defined at one side of the second housing. The poppet is configured to adjust an area of a space opened by the orifice discharging the hydrogen. The hydrogen flowing into the second housing is discharged through a space between the other side opposite to the one side of the second housing and the poppet to move to the orifice.

摘要： A solenoid valve includes: a valve housing having, at one end thereof, an inlet port through which a fluid is introduced and having, at the other end thereof, an outlet port through which the fluid is discharged; a solenoid provided in the valve housing and disposed between the inlet port and the outlet port; a first plunger provided at one end of the solenoid adjacent to the inlet port and configured to selectively open or close the inlet port by being rectilinearly moved by the solenoid; a first spring member configured to provide elastic force to allow the first plunger to move in a direction in which the first plunger closes the inlet port; a second plunger provided at the other end of the solenoid adjacent to the outlet port and configured to selectively open or close the outlet port by being rectilinearly moved by the solenoid in a direction opposite to the movement direction of the first plunger; and a second spring member configured to provide elastic force to allow the second plunger to move in a direction in which the second plunger closes the outlet port. The solenoid valve has a simplified structure while ensuring sealability.

摘要： The present disclosure relates to a valve device including a valve base having a discharge flow path through which a target fluid is discharged, a plunger configured to be rectilinearly movable from a first position at which the plunger closes the discharge flow path to a second position at which the plunger opens the discharge flow path, a solenoid configured to provide driving power for moving the plunger, and an anti-freezing member connected to the plunger and configured to prevent freezing of the target fluid in the discharge flow path by moving in the discharge flow path in conjunction with a movement of the plunger, thereby obtaining an advantageous effect of preventing the discharge flow path through which the target fluid is discharged from being clogged, and of improving safety and reliability.
