Title: Reinforced electrolyte membrane

Abstract

An electrolyte membrane having a proton conducting polymer reinforced with a nanofiber mat made from a nanofiber comprising a fiber material selected from polymers and polymer blends; wherein the fiber material has a fiber material proton conductivity; wherein the proton conducting polymer has a proton conducting polymer conductivity; and wherein the fiber material proton conductivity is less than the proton conducting polymer conductivity, and methods of making. In some embodiments, the nanofiber further comprises a proton conducting polymer.
