Abstract
Improved membrane electrode assemblies, cation-associating components thereof, and methods of making and treating the same are provided. Membrane electrode assemblies may include an ionomer having a first pKa value, and a water-insoluble net polymer having a weakly-acidic functional group, wherein the weakly-acidic functional group has a second pKa value greater than the first pKa value.
