摘要： A stack plate device for a humidifier for a fuel cell system includes first stack plates and second stack plates being stacked one on top of each other alternately in a stacking direction, top sides of the first stack plates facing bottom sides of the second stack plates, top sides of the second stack plates facing bottom sides of the first stack plates, and each of the first stack plates and the second stack plates comprising a peripheral frame that encloses a through-opening and has an inflow region and an outflow region. First flow channels and second flow channels are formed in the first stack plates and the second stack plates and formed transversely to one another, the first flow channels and second flow channels being separated by moisture-permeable layers.

摘要： A humidifying device has a plate stack with channel plates stacked in stacking direction in the plate stack. The channel plates have a longitudinal axis perpendicular to the stacking direction. One or more channel plates have a first and a second channel partial plate arranged on each other in stacking direction, and each provided with a circumferentially extending frame and stays arranged between oppositely positioned sides of the frame. The stays are slanted to the longitudinal axis. The stays of the first and second channel partial plates cross each other, viewed in the stacking direction. Semipermeable layers separate a first group of flow channels and a second group of flow channels from each other in the plate stack. Flow channels of the first group alternate with flow channels of the second group in the stacking direction. The first or second group of flow channels extends along the longitudinal axis.
