Nafion Humidifiers Find New Applications, Including Fuel Cells

Perma Pure Inc.simplicity and selectivity of PH- and MH-Series humidifiers using Nafion tubing from <%=company%> have recently opened several new applications for this membrane technology. Although Nafion dryers have been used by the instrument industry for years, humidifiers based on the same principle are a recent development. The humidifiers are finding increasing use with fuel cells, particle measurement apparatus, and in respiratory care.

PH- and MH-Series humidifiers add water vapor to gases without altering concentrations of other gases already present. Particles are also not altered. Humidifying is a self-regenerating, continuous process. The humidifiers are ruggedly constructed yet light in weight, with no moving parts, no power requirements, and very high corrosion resistance.

For fuel cells or other applications where high humidity is desired, these humidifiers can completely saturate gases with water, from small flows of a few hundred milliliters with the MH-Series to thousands of liters per minute with the PH-Series. Water can be recovered from exhaust gases and returned to the process, or liquid water can serve as the source of humidity.

In respiratory care, treatment of supplemental oxygen by MH-Series humidifiers prevents patient dehydration without the noise of bubblers or the requirement for sterile water. In particle measurement apparatus, humidification assists in detection of extremely small particles by increasing their size.
