Abstract

The invention relates to a stack of plates (400) for a humidifier (100), in particular for a fuel cell system, having a plurality of first and second support plates (100, 200) alternately following one another in a stack direction (500). First and second groups of flow ducts (410, 420) are designed in the stack of plates (400), each of which is separated by selectively permeable membranes (110, 210). Two successive first (100) and second support plates (200) in the stack direction (500) are in each case connected to one another in a fluid-tight manner by a connecting portion (150,250) on at least two first sides (124,224) opposing one another transversely to the stack direction, while an inflow and/or outflow area is designed between the support plates (100, 200) on at least two of its second sides (122,222) opposing one another transversely to the stack direction in each case. The connecting portions (150,250) are each formed by a double bead (152,252) on one of the support plates (100,200) and a corresponding single bead (160,260) on the other support plate (100,200), which is accommodated at least in the double bead (152,252). Furthermore, the invention relates to a humidifier (1000) for a fuel cell system.
