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.

Reinforced electrolyte membrane

A fuel cell electrode layer may include a catalyst, an electronic conductor, and an ionic conductor. Within the electrode layer are a plurality of electronic conductor rich networks and a plurality of ionic conductor rich networks that are interspersed with the electronic conductor rich networks. A volume ratio of the ionic conductor to the electronic conductor is greater in the ionic conductor rich networks than in the electronic conductor rich networks. During operation of a fuel cell that includes the electrode layer, conduction of electrons occurs predominantly within the electronic conductor rich networks and conduction of ions occurs predominantly within the ionic conductor rich networks.
