Abstract

The invention relates to a discharge valve. The discharge valve is arranged in a recirculation line, and gas discharged from a fuel cell stack recirculates to the stack through the recirculation line. The discharge valve opens or closes a discharge line through which a fluid in the recirculation line is discharged. The discharge valve includes a valve body connected to the discharge line and a drive part disposed in the valve body to be movable vertically. A diaphragm is coupled to a lower end of the drive part and selectively opens or closes the discharge line based on the vertical movement. The drive part switches between a closed state in which the discharge line is closed by the diaphragm, a first opened state in which the discharge line is opened to a first opening degree, and a second opened state in which the discharge line is opened to a second opening degree greater than the first opening degree.
