(482e) Development of Polymer Electrolyte Membrane and Ionomer Binder Materials for Electrochemical Energy Conversion Technology
AIChE Annual Meeting
Tuesday, November 17, 2020 - 8:45am to 9:00am
In this presentation, I will highlight recent progress at the Bae group of Rensselaer Polytechnic Institute in the development of advanced hydroxide-conducting polymers for applications in AEMs and electrode ionomers. We have developed new synthetic methods that produce polymer design made of all CâC bond backbone and a flexible chain-tethered quaternary ammonium group and that provide an effective solution to the problem of alkaline stability. The advantage of good solvent processability and convenient scalability of the reaction process has generated considerable interest of these polymers, and they are considered leading candidates for commercial standard AEM. AEM fuel cell and electrolyzer tests of some of the developed polymer membranes showed excellent performance, suggesting that this new class of HCPs opens a new avenue to electrochemical devices with real-world applications.
