    摘要: Anode-supported high-temperature fuel cells with a substrate and an anode of stabilised zirconium dioxide and metallic nickel can be destroyed by air penetrating on the fuel gas side. Reoxidation causes the volume of the nickel in the anode to change. The resultant mechanical stresses may destroy the gas-impermeable electrolyte. The invention provides oxygen scavengers that can be produced at low cost for the anode, which more effectively bind the oxygen that penetrates on the fuel gas side than oxygen scavengers according to the prior art.
