Provided according to some embodiments of the invention are anion exchange polyelectrolytes that include an at least partially fluorinated polyaromatic polymer backbone; and at least one cationic functional group pendant therefrom. Also provided are anion exchange membranes (AEMs) formed from at least one anion exchange polyelectrolyte according to an embodiment of the invention, and fuel cells including such AEMs.

Anion exchange polyelectrolytes

A fuel cell () includes a cation exchange membrane (), a first anion exchange membrane () and a second anion exchange membrane (). The cation exchange membrane () has a first side and an opposite second side. The first anion exchange membrane () has a first exterior surface and an opposite first interior surface disposed along at least a portion to the first side of the cation exchange membrane (). A catalyst () is embedded along the first exterior surface. The second anion exchange membrane () has a second exterior surface and an opposite second interior surface disposed along at least a portion to the second side of the cation exchange membrane (). A catalyst () is embedded along the second exterior surface. A stack of fuel cells () include a first fuel cell () with an acidic first anode () that is electrically coupled to an alkaline second cathode () of a second fuel cell ().
