Abstract
An anode discharge valve for a fuel cell system includes a valve main body which is installed in a hydrogen recirculation line of a fuel cell stack; a drive shaft which is rotatably installed in the valve main body, and coupled to an opening member which selectively opens a hydrogen discharge port by being rotated; and a mechanism which is connected to a hydrogen inlet port of the valve main body so as to form a hydrogen inflow path, and operates to rotate the drive shaft as a pressure of hydrogen inflowing through the hydrogen inflow path increases.
