Title: High durability fuel cell components with cerium oxide additives

Abstract

A fuel cell membrane electrode assembly is provided comprising a polymer electrolyte membrane which comprises a highly fluorinated polymer electrolyte and at least one cerium oxide compound dispersed therein. In addition, a method of making a fuel cell polymer electrolyte membrane is provided comprising the steps of: a) providing a highly fluorinated polymer electrolyte comprising acidic functional groups; b) dispersing therein at least one cerium oxide in an amount so as to provide between 0.01 and 5 percent of the total weight of the polymer electrolyte membrane; and c) thereafter forming a polymer electrolyte membrane comprising said polymer electrolyte.
