    摘要： 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.

    摘要： A novel method of altering extruded membrane films for PEM (polymer electrolyte membrane) fuel cells in such a manner that the membrane films swell substantially uniformly in both the in-plane x and y directions when immersed in water or ionomer solution is disclosed. The invention includes cutting a membrane film from an extruded membrane sheet in a diagonal orientation with respect to the membrane process direction of the membrane sheet. The membrane film exhibits reduced internal stress as compared to conventionally-prepared membrane films and allows a more even distribution of pressure in a fuel cell stack, thereby reducing the incidence of swollen membrane-induced failure mechanisms in the fuel cell stack.

    摘要： A method for forming a nanocapillary network comprises dissolving a polyelectrolyte in a solvent to form a solution; electrospinning the solution to extract polyelectrolyte fibers; and organizing the polyelectrolyte fibers into a network. The method can further comprise processing the network to increase the density of the polyelectrolyte fibers in the network. The method can also further comprise processing the network to interconnect polyelectrolyte fibers. A method for forming a proton exchange membrane comprises dissolving a polyelectrolyte in a solvent to form a solution; electrospinning the solution to extract polyelectrolyte fibers; organizing the polyelectrolyte fibers into a network; and impregnating the network with a polymer to fill voids between polyelectrolyte fibers of the network.
