Gas-liquid separator for separating at least one liquid component from a gaseous component

A gas-liquid separator (2) of a fuel cell system (1) which comprises a recirculation pump (9), the gas-liquid separator (2) for separating at least one liquid component from a gaseous component with a collecting tank (12) which is supplied with a medium including H2 and H2O, wherein at least the liquid component of the medium is separated into the collecting tank (12), wherein the separated portion of the medium is discharged from the collecting tank (12) via a discharge valve (46),

• wherein the gas-liquid separator (2) is integrated into a housing (11) of the recirculation pump (9), and gas is returned from the collecting tank (12) via a suction connection (29) into an inflow channel (7) or an outflow channel (20) of the recirculation pump (9),
• wherein the liquid component of the medium comprises H2O and the gaseous component of the medium comprises H2,
• wherein the gas-liquid separator (2) has a separating edge (8),
• wherein one of the inflow channel (7) or the outflow channel (20) has a curvature (19) with a radius (17), and
• wherein the separating edge (8) is configured such that, when the medium is flowing through the curvature (19), the medium meets the separating edge (8) such that the separating edge (8) deflects the H2O into the collecting tank (12).
