NOVELTY - The humidification cell of a fuel cell device comprises a first outer plate (9a) and a second outer plate (9b). A gas chamber (21), a humidification water chamber (31) and a water-permeable membrane (5) separating the two chambers are arranged between the first outer plate and the second outer plate. A first water-permeable support element is arranged between the first outer plate and the water-permeable membrane. A second water-permeable support element is arranged between the water-permeable membrane and second outer plate. The first and second support elements are made of a woven fabric.    USE - Used as a humidification cell of a fuel cell device.    ADVANTAGE - The humidification cell exhibits improved operating characteristics and simple structure thus increasing service life and efficiency of the fuel cell device.    DETAILED DESCRIPTION - The humidification cell of a fuel cell device comprises a first outer plate (9a) and a second outer plate (9b). A gas chamber (21), a humidification water chamber (31) and a water-permeable membrane (5) separating the two chambers are arranged between the first outer plate and the second outer plate. A first water-permeable support element is arranged between the first outer plate and the water-permeable membrane. A second water-permeable support element is arranged between the water-permeable membrane and the second outer plate. The first and second support elements are made of a woven fabric that consists of a fluoroplastic material. The fabric comprises a twill-weave fabric, and has an air passage of 260 1/m2s at 2 mbar and a thickness of 370 mu m. The first outer plate, the first support element, the water-permeable membrane, the second support element and the second outer plate abut against each other.
