| 简介 |
Composite electrolyte materials include composites comprising 8YSZ in a range of 50-95%, balance 3YSZ. Either the 8YSZ or the 3YSZ can be substituted with a composition having the general formula A1-x-yBxCy where : A=Zr0.84Y0.16O2; 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=Al2O3 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. |
