Provided is a fuel cell membrane humidifier in which humidification efficiency is improved by preventing differential pressure loss in a humidification module. The fuel cell membrane humidifier performs moisture exchange between a first fluid and a second fluid and includes a mid-case, a second fluid inlet through which the second fluid is introduced into the mid-case, a second fluid outlet through which the second fluid is discharged to outside, a partition wall configured to divide an inner space of the mid-case into a first space and a second space, and at least one cartridge located in the mid-case and configured to accommodate a plurality of hollow fiber membranes therein. A cross-sectional area of the second fluid inlet is equal to or greater than a total area of windows constituting a first mesh hole unit and arranged in a mesh shape in the at least one cartridge for fluid communication with the first space.
