Patent ID: 10516178

Abstract:
A fuel cell system (1) in which a water separator (110) for separating liquid water from an exhaust gas (6, 4) of a fuel cell (10) of the fuel cell system (1) is fluid-mechanically coupled into an exhaust gas path (32, 22) of the fuel cell system. A water recirculator (120) is fluid-mechanically coupled into the fuel cell system (1), with the aid of which at least a portion of the water of the water separator (110) is once again providable to the fuel cell (10). Moreover, a method for recirculating water in a fuel cell system (1), in which liquid water of a fuel cell supply (30, 20) of the fuel cell system (1) is withdrawn at a removal site at/in the fuel cell supply (30, 20). The water upstream from the removal site is provided to the same fuel cell supply (30, 20) and/or to some other fuel cell supply (20, 30) of the fuel cell system (1).
