Abstract
Official abstract text for this publication.
A membrane humidifier assembly for a membrane humidifier for a fuel cell system and a method for making the same is disclosed, the method comprising the steps of providing a material for forming a diffusion medium; forming a plurality of channels in the material with one of a channel-forming roller, a means for etching the material, and a press for forming the diffusion medium; and providing a pair of membranes, wherein the diffusion medium is disposed between the pair of membranes.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for making a membrane humidifier assembly for a membrane humidifier for a fuel cell system, the method comprising the steps of: providing a planar material for forming a first diffusion medium having a thickness, wherein the planar material allows passage of water vapor therethrough; forming a plurality of channels in the planar material for forming the first diffusion medium, wherein the plurality of channels do not traverse the thickness of th…
