    Abstract: The fuel cell membrane is a polymer electrolyte (or polyelectrolyte) membrane formed from a blend of sulfonated poly(ether ether ketone) (SPEEK) and phosphonated polysulfone in the ester form (PPSU-E), where the sulfonated poly(ether ether ketone) and the phosphonated polysulfone each form about 50 wt % of the polyelectrolyte membrane. The polyelectrolyte membrane is made by dissolving a mixture of SPEEK and PPSU in the ester form (PPSU-E) in dimethylacetamide (DMAc) at room temperature to form a solution. The SPEEK/PPSU-E mixture has a concentration of between about 10 wt % and about 15 wt % in the solution. The solution is then stirred and left to release air bubbles therefrom. The DMAc is then evaporated from the solution, leaving the resultant polyelectrolyte membrane, which is then washed and dried.

    Abstract: A proton exchange membrane (PEM) with an ion exchange capacity of not less than 1 molar equivalent per kilogram and less than 20% water swelling is provided. The PEM includes a polymer having a polyphosphazene backbone with a polyaromatic functional group linked to the polyphosphazene as a polyaromatic side chain, a non-polyaromatic functional group linked to the polyphosphazene as a non-polyaromatic side chain, and an acidic functional group linked to the non-polyaromatic side chain. The polyaromatic functional group linked to the polyphosphazene provides for increased thermal and chemical stability, excellent ionic conductivities and low water swelling. The mole fraction of polyaromatic functional groups linked to the polyphosphazene backbone is between 0.05 and 0.60.
