A device for connection of a line element to a component is provided. The line element ends in a connection housing or is connected to such a connection housing. A releasable fixing arrangement is configured between the connection housing and the component. A line section extending in the connection housing is heated by an electric heating wire. The heating wire externally surrounds the line section. The heated line section projects in the direction of the component so far over the region for releasable fixing of the connection housing on the component that it ends in the inner space of the component.

An enclosed separator unit for incorporation into a gas supply device of a fuel cell system, to separate liquid from the gas supply device, includes a separator for separating the liquid. A housing encloses the separator unit which is arranged in a gas spacein the housing and/or is in thermal contact with the gas space. A line system is provided for discharging the liquid from the separator, and at least one fluid dynamically active functional component is arranged in the line system, in the gas space

In a method for operating a fuel cell system having recirculation blower arranged in a fuel cell circuit, fuel discharged from the anode exhaust is fed back to the inlet side of the fuel cell system via the recirculation blower. The direction of flow in the fuel return line is reversed in at least a portion of the return line, in an alternating manner.

A seal arrangement in a fuel cell device seals against leaks in a mechanical joint between two components which convey a liquid and/or a gaseous process mediumin a media chamber of the fuel cell device. The seal arrangement has a first sealing member which extends around the media chamber in an installed state, and is in active connection with the components. A second, surrounding sealing member is arranged facing away from the media relative to the first sealing member and is formed of a different material from the first sealing member and/or has a different geometry.

In a device for conveying liquids or moist gases through a closed duct in a vehicle fuel cell power systems, freezing of the duct is prevented by providing a part of its internal wall flow passages or flow chambers with a nonwoven material. The nonwoven material absorbs liquid in disperse form at low temperatures through its capillary action and inhibits premature ice formation.
