Abstract: The present invention relates to a fuel cell membrane humidifier capable of preventing a humidification efficiency decrease caused by a pressure difference between the inside and the outside of a membrane humidifier. A fuel cell membrane humidifier according to an embodiment of the present invention comprises: a middle case having a module insertion part formed therein; a cap case coupled to the middle case; a hollow fiber membrane module inserted in the module insertion part; and an active pressure buffer part which is formed between the middle case and the module insertion part and prevents expansion of the module insertion part by a pressure difference between the inside and the outside of the middle case according to an output state of a fuel cell or relieves the pressure difference therebetween.
