摘要： The invention relates to a stack plate device (400) for a humidifier (1000), in particular for a fuel cell system, the stack plate device (400) including a plurality of first and second stack plates (100, 200) being stacked one on top of each other alternately in a stacking direction (500), with each stack plate (100, 200) comprising a peripheral frame (120, 220), wherein at least first and second groups of flow channels (410, 420) are formed in the stacked stack plates (100, 200), the flow channels (410, 420) being formed transversely to one another and being separated by semi-permeable layers (110, 210), in particular moisture-permeable layers (110, 210). The peripheral frames (120, 220) comprise one or more connecting elements (140, 240; 152) and the connecting elements (140, 240; 152) of adjacent stack plates are arranged in an interlocking manner.
