Abstract: A humidifying device for transferring water and/or water vapour from waste air of a waste air flow to supply air of a supply air flow is provided. In the compensating chamber of the housing of the humidifying device, at least one spreading means is arranged, which spreads apart the plate stack of the humidifying device and the housing cover closing the housing in the direction of the longitudinal axis.

Abstract: A membrane assembly for a humidification device of a fuel cell system may include a membrane. The membrane may be permeable to water and impermeable to air. The membrane may extend in a flat form in a longitudinal direction and in a transverse direction that is transverse with respect to the longitudinal direction in an extent plane. The membrane may include in a height direction extending transversely with respect to the longitudinal direction and transversely with respect to the transverse direction a top side and a bottom side averted from the top side. The membrane may include an encircling outer margin in the extent plane. The outer margin may have an upper edge at the top side and a lower edge at the bottom side, between which an encircling face surface extends.

Abstract: A humidifying module for humidifying a fluid, such as an operating fluid of a fuel cell of a motor vehicle, is disclosed. The humidifying module includes a humidifier block including a plurality of first fluid paths through which a first fluid is flowable and a plurality of second fluid paths through which a second fluid is flowable. The plurality of first fluid paths and the plurality of second fluid paths in the humidifier block are fluidically separated from each other via a plurality of gas-tight and humidity-permeable membranes. A liquid separator is provided that is fluidically connected to one of the first fluid paths for flow-through with the first fluid and the second fluid paths for flow-through with the second fluid.

Abstract: A humidifier block and a method for producing a humidifier block are disclosed. The humidifier block may include a plurality of membranes each having a cavity for passing a through-flow and a jacket surrounding the cavity in a circumferential direction. The jacket may be moisture-permeable. At least one strip-shaped carrier may be fitted with the plurality of membranes, and the plurality of membranes may arranged in a longitudinal direction parallel to one another and adjacent to one another on the at least one carrier. The at least one carrier fitted with the plurality of membranes may be shaped into the humidifier block such that the plurality of membranes are arranged adjacent to one another in a transverse direction running transversely to the longitudinal direction and adjacent in a height direction running transversely to the longitudinal direction and transversely to the transverse direction.
