The invention relates to a moisture exchanger (1) for media flows, in particular a humidifier (1) for a fuel cell (20), comprising: a first supply line (3) for a first fluid (FL1) to be dehumidified; a second supply line (4) for a second fluid (FL2) to be humidified; a first discharge line (5) for the second fluid (FL2), which, upon exiting the moisture exchanger (1), is in a moistened state; a second discharge line (6) for the first fluid (FL1), which, upon exiting the moisture exchanger (1), is in a moisture-reduced state; and a stack (7) of moisture-permeable membranes (8) and distributor plates (9) arranged between the membranes for guiding the fluids (FL1, FL2) onto the membranes, the distributor plates having, on their surface (9A, 9B), flow channels for the fluids (FL1, FL2) and being fluidically interconnected by means of collecting lines (15, 16, 17, 18). The distributor plates each have through-holes (12A, 12B, 12C, 12D) in opposite end regions (9D, 9E) of the planar extent of the distributor plates. The through-holes of the stacked distributor plates overlap to form the collecting lines, which extend substantially perpendicularly to a surface plane of the distributor plates. The invention further relates to a fuel cell system, in particular of a motor vehicle, which fuel cell system comprises at least one fuel cell (20) and one moisture exchanger (1) of this type.
