Researchers at RPI have developed a prototype hydrocarbon-based membrane for use in AE fuel cells and electrolyzers. This membrane can operate in a stable manner at elevated temperatures with the potential to provide enhanced operational performance. This membrane could possibly effectively participate in the growing fuel cell/electrolyzer market, as tested, the DPE membrane provides increased Tg values as compared to non-functionalized PS materials and increased Tg values as compared to main chain Nafion-117. Increased Tg values for the DPE membrane as compared to non-functionalized PS/main chain Nafion-117 should yield increased thermal stability in constructed anion AE membranes in fuel cells or water electrolyzer devices.
