Abstract
A polymer electrolyte membrane includes an ion-conducting polymeric electrolyte material and platelets, distributed through the polymeric electrolyte material. The platelets have an aspect ratio of length to thickness of at least 2:1. The platelets are aligned generally parallel to a length of the membrane. The platelets can be functionalized with free radical scavengers, or other moieties, to extend the lifetime of the membrane or of a membrane electrode assembly incorporating the membrane.
