Evaluating Performance of Polymer Membranes for Fuel Cell Humidifier Applications

Hydrogen fuel cells require humidification in order to operate effectively, yet, at the same time produce a constant stream of moisture through their exhaust. Membrane fuel cell humidifiers provide a method of ‘recycling’ this moisture, thereby saving energy. They work similarly to heat exchangers, but take advantage of special polymer membranes in order to exchange moisture. Fuel cell environments can be very taxing on membranes, reaching temperatures of 95C, so selecting the right membrane material is of utmost importance. In this project, two test stations will be constructed to evaluate candidate membrane materials. The first will test for permeability to moisture under high temperature conditions. The second will create an accelerated aging environment, simulating the effects of extended use in the field. In conjunction, these two stations will be able to thoroughly evaluate candidate membrane materials for membrane-fuel cell humidifiers.
