Abstract
A composite fuel cell polymer electrolyte membrane. The composite membrane includes a polymer electrolyte membrane base material including first and second inorganic particles. The first and second inorganic particles are interspersed within the polymer electrolyte membrane base material and each other. The first and second inorganic particles have first and second surface properties and the first surface property is different than the second surface property.
