Abstract: A humidifier device for humidifying a fluid in a fuel cell system of a motor vehicle is provided. The humidifier device has a housing, in which is arranged at least one membrane, and a bypass channel for bypassing the at least one membrane. The bypass channel has a non-circular cross-section.

Abstract: A humidifier (1), including at least one housing (2), in which multiple fibers (3) constructed as water-permeable hollow fiber membranes are arranged, wherein a first air stream (4) is passed inside the fibers (3) and a second air stream (5) is passed outside the fibers (3), and wherein the housing (2) is of flattened design.

Abstract: A humidifier including a housing which is used to receive a humidifier module. The housing can be connected by the housing cover and is provided with at least one first sealing element, which seals the humidifier module in relation to the housing. The humidifier module is arranged in an axially displaceable manner on the first sealing element.

Abstract: A lattice structure for the passage of a first medium against a second medium with transverse webs and longitudinal webs, lattice openings with a clear width of ?300 ?m being arranged between the transverse webs and the longitudinal webs. On at least one side of the lattice structure, the transverse webs and/or the longitudinal webs have a rib arrangement of ribs projecting vertically to the lattice plane, at least one first group and a second group of ribs being arranged which differ from one another at least by their heights H1, H2 with H1>H2. A vessel with at least one water inlet window and an air outlet window, both windows being provided with the lattice structures.

Abstract: The present invention relates to a humidifier module (1) for humidifying a fluid in a fuel cell system of a motor vehicle, with a housing (2) having two housing parts (2a, 2b), wherein a humidifier unit (3) with at least one membrane is arranged between the housing parts (2a, 2b), wherein the humidifier unit (3) is formed in the shape of a single cartridge.
