Abstract
A membrane electrode assembly includes an anode catalyst layer, a cathode catalyst layer, and a polymeric blend proton exchange membrane interposed between the anode catalyst layer and the cathode catalyst layer. The polymeric blend proton exchange membrane includes a scaffold polymer and a polyacid polymer. The polyacid polymer being formed from a polyacid polymer precursor. Characteristically, the scaffold polymer and the polyacid polymer precursor have matching solubility parameters.
