Fuel cell membrane

Fuel cell membrane

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...

description 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.
