Abstract
A control flap assembly for a gas flow in a fuel cell system, in particular in a vehicle, includes a control flap housing providing a gas flow channel, and a control flap with a disk-like control flap body which can be adjusted in the control flap housing between a closed position preventing a gas flow through the gas flow channel and at least one open position opening up the gas flow channel for a throughflow. A control flap seat is provided on the control flap housing, and a sealing region bearing against the control flap seat in the closed position of the control flap is provided on the control flap. The sealing region includes resilient sealing material on an external peripheral region of the control flap body.
