Device For Cooling And Dehumidifying Gases, Method For Cooling And Dehumidifying Gases, And Vehicle With A Fuel Cell System And A Device For Cooling And Dehumidifying Fuel Cell Exhaust Air

A method for cooling and dehumidifying gases, the method comprising:

• leading a gas to be cooled and dehumidified through a gas inlet by way of a first hollow body to a gas outlet,
• leading a coolant through a coolant inlet to a coolant outlet by way of a second hollow body at least partly enclosed by the first hollow body,
• rotating one of the first hollow body and the second hollow body and an at least one turbulence-generating body arranged thereon relative to the other hollow body, which turbulence-generating body extends in the direction of the other hollow body, and
• leading away condensate that collects in the first hollow body.

A vehicle comprising a fuel cell with an exhaust air outlet connectable to the gas inlet of a device comprising:

• a first hollow body with a gas inlet, a gas outlet and a condensate drain;
• a second hollow body with a coolant inlet and a coolant outlet;
• and
• a drive unit;
• wherein the first hollow body encloses the second hollow body at least in part,
• wherein one of the first hollow body and the second hollow body is pivotally held relative to the other hollow body and comprises at least one turbulence-generating body extending in the direction of the other hollow body, and
• wherein for rotating the pivotally held hollow body the drive unit is couplable to the hollow body.
