A fuel cell system includes at least one fuel cell, an oxidant conveyor, a humidifier and at least one water sink. The oxidant conveyor conveys an oxidant through a supply line to the fuel cell. The humidifier introduces water into the oxidant flow. The humidifier is arranged in and/or downstream of the oxidant conveyor and upstream of the fuel cell. The water sink is arranged between the fuel cell and the oxidant conveyor. The water sink is formed and arranged in the supply line in such a way that it prevents liquid water located in the supply line from flowing to the oxidant conveyor.

A method is provided for operating a fluid conveying device of a motor vehicle having at least one aerodynamic bearing. The method reduces the rotational speed of the aerodynamic bearing to a rest speed, wherein the rest speed is below a lifting speed, in which case the bearing builds up an air film for bearing free of mixed friction, and wherein the rest speed is above a lowering speed, in which case the bearing has reduced the air film such that mixed friction occurs. The fluid conveying device is operated at the rest speed.
