Abstract: A humidifier, a device including a fuel cell, and a motor vehicle. The humidifier of the includes at least one humidifying duct and is designed in such a way that a first gas to be humidified can be conducted in the humidifying duct in a direction of flow and, separated by a water-permeable material, past a humidifying second gas so that water is transferred from the second gas to the first gas. The humidifier includes a cross-sectional area of the humidifying duct available to the first gas tapers in the direction of flow. The fact that the cross-sectional area tapers results in a drop in pressure along the humidifying duct, and the drop in pressure reduces, compensates or overcompensates an increase in pressure resulting from the increasing humidification, so the partial difference in pressure between the first gas and the second gas remains large over the distance of the humidifying duct in spite of the transfer of humidity.
