Abstract
The present teachings describe electrolytes and electrodes (anodes and cathodes), usually as a layered system, for use in solid oxide cells such as solid oxide fuel cells and electrolyzers. The present teachings also describe methods of using the electrolytes and electrodes and solid oxide cells as well as methods of making the electrolytes, electrodes, and SOCs.
