Fluid guidance unit for a fuel cell device

Abstract

The present invention relates to a fluid guidance unit (100) for a fuel cell device (102), wherein the fluid guidance unit (100) comprises: a base body (106) in which an interior space (114) is formed, wherein the base body (106) further comprises at least one supply channel (116, 118) for supplying a first fluid flow (120), in particular an exhaust gas flow (120), into the interior space (114); a discharge channel (110) which is at least partially arranged in the interior space (114) and serves to discharge a second fluid flow (122), in particular a recirculation flow (122) comprising at least parts of the exhaust gas flow (120), from the interior space (114);and a passive recirculation device (112) which is arranged in the interior (114) of the base body (106), wherein a third fluid flow (124), in particular a propulsion flow (124) containing a fuel medium, can be supplied to the interior (114) via the passive recirculation device (112), and wherein a fourth fluid flow (126), in particular a recirculation flow (126) containing at least parts of the exhaust gas flow (120) and at least parts of the propulsion flow (124), can be discharged from the interior (114) by means of the passive recirculation device (112). Furthermore, the present invention relates to a fuel cell device (102) for a vehicle and to methods for operating a fuel cell device (102).
