Abstract

The present invention relates to a packing unit for a fuel cell humidifier, and a fuel cell humidifier, the packing unit comprising: a first packing body airtightly coupled to one end of a mid-case through mechanical assembly so that a first cap fluidically communicates only with hollow fiber membranes; and a condensate water discharge portion formed in the first packing body, wherein the condensate water discharge portion has one end fluidically communicating with the inside of the first cap and has the other end fluidically communicating with the inside of the mid-case so that condensate water located inside the first cap is discharged to the inside of the mid-case.

Dependent claims

A packing unit provided in a humidifier for fuel cells, the humidifier comprising a humidifying module configured to humidify dry gas to be supplied to a fuel cell stack using wet gas, a first cap coupled to one end of the humidifying module, and a second cap coupled to the other end of the humidifying module, the packing unit comprising:

a first packing body airtightly coupled to one end of a mid-case of the humidifying module through mechanical assembly such that the first cap is only in fluid communication with hollow fiber membranes of the humidifying module;
and
a condensate discharge portion formed in the first packing body, wherein
one end of the condensate discharge portion is in fluid communication with an interior of the first cap and the other end of the condensate discharge portion is in fluid communication with an interior of the mid-case to discharge condensate in the first cap into the mid-case.
