Abstract: A fuel cell exhaust-gas system, in particular for a vehicle, includes a condenser for receiving water-containing fuel cell exhaust gas that has been discharged from a fuel cell unit. A separator, arranged downstream of the condenser, is provided for separating off water that has been condensed out of the water-containing fuel cell exhaust gas fed to the condenser. The separator includes an at least regionally arcuately curved separating channel delimited by a channel wall. The separating channel is surrounded at least in the region of an arc outer side by a separating chamber. A plurality of separating openings, which connect the separating channel to the separating chamber, are provided in the channel wall.

Abstract: A mixing section is for an exhaust system of an internal combustion engine. The mixing section intermixes exhaust gas and reagent and includes a mixing-section housing, enclosing a mixing chamber with a housing base. At least one exhaust-gas inlet opening admits exhaust gas into the mixing chamber and is provided in the housing base. A reagent dispenser dispenses reagent into the mixing chamber substantially in a main dispensing direction. The mixing section also includes a reagent-receiving arrangement for receiving reagent dispensed into the mixing chamber and the reagent-receiving arrangement includes a plurality of reagent receivers succeeding one another in the main dispensing direction. Each reagent receiver defines a reagent-receiving area positioned facing toward the reagent dispenser.

Abstract: A gas/gas mixer for introducing gas, especially air, into the exhaust gas stream of an internal combustion engine, includes a mixer body (32) that is elongated in the direction of a body longitudinal axis (L). A plurality of gas passage openings (38) are provided in a wall (36) of the mixer body (32) enclosing a volume of gas to be introduced (42) in the mixer body (32). The mixer body (32) is configured with a flattened cross-sectional profile, flattened obliquely to the body longitudinal axis (L).
