Abstract

A humidification device is provided with at least one stacked unit with water vapor-permeable membranes arranged parallel and spaced apart relative to each other. The membranes each have an edge area framed by frames. The frames are formed by a film composite of a lower film and an upper film, wherein the lower and upper films of the film composite clamp the edge area of one or more of the membranes therebetween. The lower and upper films of the film composite are fixedly connected to each other. Alternatively, the frames are formed by a thermoplastic yarn that is sewn into the edge area of one or more of the membranes, respectively, wherein the thermoplastic yarn is reshaped by heat and pressure.
