    摘要： A solenoid valve for a fuel cell system is provided that includes a valve housing and a valve body disposed within the valve housing having an inflow passage through which hydrogen flows in, a discharge passage through which hydrogen is discharged, and a valve passage connecting the inflow passage and the discharge passage. A solenoid is disposed within the valve housing and a plunger is supported within the solenoid by a valve spring. and the plunger is movable upward and downward while corresponding to the direction of the valve passage. A pressure balance unit is disposed extraneous to the plunger to press the plunger with force corresponding to excessive pressure greater than a determined inflow hydrogen pressure applied through a branch passage that branches off from the inflow passage.

    摘要： A system and method are provided for compensating an offset of a pressure sensor. The system includes a pressure sensor that is configured to detect pressure and a power management module that is configured to automatically supply power to a controller connected to the power management module or terminate the supply of power after a preset time to thereby turn the controller on or off. The system further includes the controller connected to the power management module and configured to determine the offset of the pressure sensor based on a pressure value which is detected by the pressure sensor when the power is supplied from the power management module. The system also includes a memory configured to store the determined offset.
