Abstract
A forward check valve and a fuel cell system are provided which include a valve portion including a valve body, a supporting portion, a hole, and a fixation portion. The valve body contacts a valve seat when the valve portion is accommodated in an opening. The supporting portion supports the valve body so that the valve body is movable in directions in which the valve body moves towards and away from the valve seat. The fixation portion contacts an inner peripheral surface defining the opening of a valve housing to fix the supporting portion when the valve portion is accommodated in the opening. The fixation portion includes protruding portions that protrude from a mount surface of the valve housing when the valve portion is accommodated in the opening. By fitting the valve portion to the opening, the valve portion is accommodated in the opening of the valve housing.
