MIXED METALLIC OXIDES AS SCAVENGERS FOR FLUORINATED ION EXCHANGE POLYMERS

A mixed oxide of Si and at least one metal M comprising inorganic groups -SO3H. The addition of the mixed oxide to fluorinated polymers containing sulfonic acid functional groups increases their stability towards radical degradation when used in fuel cell applications.
