Alkaline membranes have seen significant advances in the past decade showing greatly improved performance and durability. These advances have allowed for alkaline membrane fuel cellss to demonstrate successful performance at temperatures approaching 80C, and for lifetimes into the hundreds of hours. The primary issues for these systems has been chemical stability, but now much of the focus is shifting towards issues of electrode performance and water management. Specific polymer properties such as water uptake, water management and electrocatalyst interactions have become more important and perfluorinated anion exchange membranes are of interest due to the success similar perfluorosulfonic acid polymers have shown in the more highly developed proton exchange membrane community. This presentation will focus on the advances demonstrated at the National Renewable Energy Lab in our development and implementation of perfluorinated anion exchange membranes.
