COMPOSITE MATERIALS

摘要

A mixed metal oxide material of tungsten and titanium is provided for use in a fuel cell. The material may comprise less than approximately 30 at.% tungsten. The mixed metal oxide may form the core of a core-shell composite material, used as a catalyst support, in which a catalyst such as platinum forms the shell. The catalyst may be applied as a single monolayer, or up to 20 monolayers.
