The invention relates to a fuel cell system () comprising at least one fuel cell stack () having an anode section () and a cathode section (), an ejector (), a fuel mixture line () for conveying a fuel mixture—containing primary fuel and secondary fuel—from the ejector () to the anode section (), a primary fuel line () for supplying the primary fuel to the ejector (), and a recirculation line () for returning the secondary fuel from the anode section () to the ejector (), wherein at least sections of the primary fuel line () extend through a heat exchange volume () within the recirculation line () for a heat-transmitting connection between the secondary fuel and the primary fuel.

Fuel cell system

The present invention concerns a starting burner () for a fuel cell system (), having a catalyst () with a catalyst inlet () and a catalyst outlet (), a catalyst area () being formed between the catalyst inlet () and the catalyst outlet (), and the catalyst area () being surrounded by a catalyst wall () in a passage direction (D) from the catalyst inlet () to the catalyst outlet (), and an operating fluid guide section () for supplying an operating fluid (F) to the catalyst inlet (), wherein the operating fluid guide section () is arranged outside the catalyst () at least in sections along the catalyst wall (). The invention also concerns a fuel cell system () with the starting burner () and a method for heating a service fluid (F) in the fuel cell system ().

Starting burner for a fuel cell system

The present invention relates to a generator unit () having a housing (), a fuel cell device (), which is arranged in an interior space () of the housing (), a gas-carrying duct () having an upstream opening () and a downstream opening (), a valve (), which is provided, in particular set up, to connect the interior space () to the duct () at least at times in a gas-carrying manner, a driving device (), which moves gas within the duct () from the upstream opening () to the downstream opening (), and a sensor device (), which is arranged in a downstream direction of the duct () starting from the valve () and is designed to detect at least one parameter of the gas. The present invention also relates to a method for monitoring a generator unit.
