Improved Round Trip Efficiency for Regenerative Fuel Cell Systems

Abstract

Continued improvements in membrane life and efficiency were realized through further optimization of the electrode attachment process. An MEA fabricated with 90 micron Gore membrane and Proton electrodes operating at 1.86 A/cm2 has reached 1000 hours of operation at 400 psi differential pressure and 80C with performance below 1.9V, meeting the program objectives. A 60 micron test continues to operate at similar conditions. All objectives have been met for the first phase of this project, with durability testing ongoing. Results are described in more detail in the following sections. New options on this project have been initiated and the next quarterly report will add the new tasks.
