Claim 16:
17. A method of making a proton-exchange membrane, the method comprising:
combining a polymer solution and particles comprising a proton-conducting material to form a mixture;
drying the mixture;
pulverizing the dried mixture;
optionally further processing the dried mixture comprising adding a polymer solution to the dried mixture, drying the resulting mixture, and pulverizing the resulting dried mixture;
adding a solvent to the dried mixture to form a dough; and
pressing the dough to form the membrane, wherein the membrane comprises
a polymer matrix, polymer fibers, or a combination thereof, and
the proton-conducting material distributed in the polymer matrix, on the polymer fibers, in the polymer fibers, or a combination thereof.
