| 简介 |
Composite electrolyte materials include composites comprising 8YSZ in a range of 50-95% and 5-50 wt-% 3YSZ. Either the 8YSZ or the 3YSZ can be substituted with a composition having the general formula A1-x-yBxCy where : A = Zr0.84 Y0.16O2; B = at least one of the following : Zr1-XDXO2 where : D = at least one of the group Mg, Ca, Sc, and Y, and x = 0.03 to 0.16; and Ce1-XREXO2 where : RE = at least one rare-earth element and x = 0.05 to 0.20; C = A12O3 where y = 0 to 0.20. The composite electrolyte materials are useful in solid state electrochemical devices such as solid oxide fuel cells and electrolyzers. Methods of making the same are also disclosed. |
