Device for anode gas recirculation in a fuel cell system

Abstract

A device for an anode gas recirculation in a fuel cell system includes a blower, an outer housing defining the blower, a condensate drain channel, a receiving element arranged at the outer housing, and a drain valve arranged in the receiving element. The blower incudes a rotor wheel, a delivery channel, an electric motor having a drive shaft to which the rotor wheel is attached, and a cooling channel through which an anode gas flows. The delivery channel extends from a delivery channel inlet to a delivery channel outlet. The cooling channel at least partially surrounds the electric motor of the blower. The condensate drain channel extends below the cooling channel in the outer housing. The cooling channel is fluidically connected to the condensate drain channel. The condensate drain channel is opened and closed by the drain valve so that a liquid can be drained from the condensate drain channel.
