Reinforced electrolyte membrane

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.

Proton conducting materials

The description includes materials that may be useful for fuel cell applications such as in the manufacture of fuel cell electrodes, proton exchange membranes (PEM), as catalyst additives or in tie layers designed to be thermally and chemically robust while operating within a fuel cell's harsh environment at higher temperatures and to conduct protons, with significantly higher levels of bound acidic groups, while in a low hydration state. Methods of making the materials are also described.
