Abstract
Disclosed is a media suitable for use in a humidifier. The media is water vapor exchange media composed of two components. One component is a nonwoven web for water vapor exchange. A second component includes low melt polymeric fibers such as a polypropylene nonwoven web. The second component seals the first component, preventing exchange of gas through the media. The media is suitable for humidifier components, such as a humidifier component used in a fuel cell system.
