Abstract
The invention relates to an arrangement for a cathode recirculation of a fuel cell () of a fuel cell system () with a cathode supply () for the fuel cell (), having a cathode supply path () and a cathode waste gas path (), and a flushing loop () of a stack housing () of the fuel cell () is mechanically connected in terms of fluid to the cathode supply (), wherein a recirculation fluid () can be circulated in the cathode supply () and in the flushing loop () by means of a recirculation fluid pressure generator () in the cathode supply () and/or in the flushing loop (). The invention also relates to a method for cathode recirculation of a fuel cell () of a fuel cell system () if a vehicle, in particular of an electric vehicle, wherein a recirculation fluid () is conveyed through a cathode supply path (), through the cathode chambers of the fuel cell (), and through a cathode waste gas path (), and the recirculation fluid () is also conveyed through a flushing loop () for a stack housing () of the fuel cell () as well as the stack housing ().
