Cerium and cerium oxide containing alloys, fuel cell system balance of plant components made therefrom and method of making thereof

Abstract:

A method of making a metal alloy includes providing a molten metal alloy containing chromium, cerium and at least one of iron and nickel and providing an oxidizing gas and a reducing gas into the molten metal alloy to at least partially preferentially oxidize the cerium to ceria. The metal alloy may an iron or nickel based metal alloy which contains both cerium and ceria and at least 15 wt % Cr. The metal alloy may be used to form a balance of plant component for a fuel cell system.
