Membrane humidifier for a fuel cell

摘要

The present disclosure provides a membrane humidifier for a fuel cell including: a case; a hollow fiber membrane module covering the case; a housing coupled to both ends of the hollow fiber membrane module; a plurality of hollow fiber membranes arranged in the case; and a hollow fiber membrane guide structure installed at one end or both ends of the hollow fiber membrane module and having a potting material layer formed therein to fix the plurality of hollow fiber membranes.

主权项

1. A membrane humidifier, comprising:
a case with a first end and a second end; a hollow fiber membrane module with a first end and a second end; a first housing with an inlet and a first case joining end; a second housing with an outlet and a second case joining end; a plurality of hollow fiber membranes; and a hollow fiber membrane guide, wherein the plurality of hollow fiber membranes are located within the case, the case is located within the hollow fiber membrane module so that when the first housing is fitted onto the first case end, the first case joining end abuts the first end of the hollow fiber membrane module, and when the second housing is fitted onto the second case end, the second case joining end abuts the second end of the hollow fiber membrane module, and the hollow fiber membrane guide is circumferentially connected to an end of the case, the hollow fiber membrane guide includes a potting material layer formed therein, the hollow fiber membrane guide is a structure positioned between the potting material layer and the case, and the potting material layer is divided at particular locations around the hollow fiber membrane guide to prevent thermal deformation causes by contraction and expansion of the potting material layer.
