The present invention relates to an electrolyte structure (4) coated on at least one surface with a roughened interfacial nano-crystalline layer (2). Another aspect of the present invention is a solid oxide fuel cell which includes a positive air electrode (7), a negative fuel electrode (6), an electrolyte structure interposed between these electrodes, and a roughened interfacial nano-crystalline layer interposed between the electrolyte structure and at least one of the two electrodes. The present invention also relates to methods of making the coated electrolyte and solid oxide fuel cell. |
