Roughened electrolyte interface layer for solid oxide fuel cells

摘要

The present invention relates to an electrolyte structure coated on at least one surface with a roughened interfacial nano-crystalline layer. Another aspect of the present invention is a solid oxide fuel cell which includes a positive air electrode, a negative fuel electrode, an electrolyte structure interposed between the positive air electrode and negative fuel electrode, and a roughened interfacial nano-crystalline layer interposed between the electrolyte structure and at least one of the positive air electrode and negative fuel electrode. The present invention also relates to methods of making the coated electrolyte and solid oxide fuel cell.
