Abstract: A fuel-cell exhaust system for a fuel-cell arrangement, in particular in a vehicle, includes a fuel-cell exhaust line through which fuel-cell exhaust gas can flow and a condenser having a condenser body through which the fuel-cell exhaust gas can flow. With the condenser, liquid is condensed out of the fuel-cell exhaust gas. A liquid separator is arranged downstream of the condenser.

Abstract: A fuel cell exhaust gas arrangement for a fuel cell system includes a fuel cell exhaust gas line through which fuel cell exhaust gas can flow, and a separating unit through which the fuel cell exhaust gas can flow. The separating unit includes an upstream line portion of the fuel cell exhaust gas line through which the fuel cell exhaust gas can flow in a main exhaust gas flow direction. A downstream line portion of the fuel cell exhaust gas line adjoins the upstream line portion in an opening region. A first liquid outlet opening in the opening region is provided to outlet liquid from the fuel cell exhaust gas flowing through the fuel cell exhaust gas line. A swirl flow generating unit is provided in the upstream line portion.

Abstract: A fuel cell exhaust-gas system includes at least one condenser for receiving water-containing fuel cell exhaust gas that has been discharged from a fuel cell and for discharging water-depleted fuel cell exhaust gas. The at least one condenser includes a separator for separating off water that has been condensed out of the water-containing fuel cell exhaust gas that has been fed to the at least one condenser and at least one heat exchanger, wherein the water-containing fuel cell exhaust gas that is fed to at least one condenser, and water-depleted fuel cell exhaust gas that has been discharged from at least one condenser, can flow through the at least one heat exchanger in order for heat of the water-containing fuel cell exhaust gas to be transferred to the water-depleted fuel cell exhaust gas.

Abstract: A fuel-cell exhaust arrangement for a fuel-cell system includes an exhaust line, through which exhaust gas can flow, and a muffler through which the exhaust gas can flow. The muffler includes a housing with an inlet region for exhaust gas and with an outlet region for exhaust gas. An upstream line section of the exhaust line adjoins the inlet region for exhaust gas. A downstream line section of the exhaust line adjoins the outlet region for exhaust gas. At least one muffler chamber is formed in the housing. A base of the housing separates at least one liquid-collecting chamber from at least one muffler chamber. At least one liquid-passage opening connecting at least one muffler chamber to at least one liquid-collecting chamber for exchanging liquid is provided in the base. At least one liquid-discharging opening for discharging liquid from the at least one liquid-collecting chamber is provided on the housing.
