Claim 15:
16. A method of making a proton-exchange membrane, the method comprising:
forming core-shell nanofibers comprising a core and shell, the forming comprising electrospinning a polymer to form the core comprising a polymer and electrospray coating the core or solution dipping the core to form the shell comprising a proton-conducting material, or the forming comprising co-electrospinning a solution comprising the proton-conducting material and a solution comprising the polymer to form the core that comprises the proton-conducting material and the shell that comprises a polymer; and
heat pressing the nanofibers to form the membrane, wherein the membrane comprises
the nanofibers; and
the proton-conducting material distributed on the nanofibers, in the nanofibers, or a combination thereof.
