Description: This image demonstrates how ions move in scandia-doped cubic zirconia, the new solid oxide fuel cell (SOFC) material. Oxygen (red spheres) migrates from one vacancy to another, and the oxygen must brush past cations (marked by the letter E). A membrane made of this specialized cubic zirconia could drop the temperature inside solid oxide fuel cells. Lowering the temperature means these cells could be built from less expensive materials.
