Abstract:
The invention relates to an arrangement for a cathode recirculation of a fuel cell (10) of a fuel cell system (1) with a cathode supply (30) for the fuel cell (10), having a cathode supply path (31) and a cathode waste gas path (32), and a flushing loop (50) of a stack housing (16) of the fuel cell (10) is mechanically connected in terms of fluid to the cathode supply (30), wherein a recirculation fluid (7) can be circulated in the cathode supply (30) and in the flushing loop (50) by means of a recirculation fluid pressure generator (33, 53) in the cathode supply (30) and/or in the flushing loop (50).The invention also relates to a method for cathode recirculation of a fuel cell (10) of a fuel cell system (1) if a vehicle, in particular of an electric vehicle, wherein a recirculation fluid (7) is conveyed through a cathode supply path (31), through the cathode chambers of the fuel cell (10), and through a cathode waste gas path (32), and the recirculation fluid (7) is also conveyed through a flushing loop (50) for a stack housing (16) of the fuel cell (10) as well as the stack housing (16).
