摘要： The cell of the present invention includes an element portion and a first layer. The element portion includes a first electrode layer, a second electrode layer and a solid electrolyte layer. The first electrode layer serves as a tubular support body. The solid electrolyte layer is located between the first electrode layer and the second electrode layer. The solid electrolyte layer contains an oxide as a primary component and a first content of a rare earth element. The solid electrolyte layer has a thickness of 30 μm or less. The solid electrolyte layer has a region devoid of the second electrode layer. The first layer is located in the region. The first layer contains the oxide as a primary component and a second content of the rare earth element. The second content is different from the first content. The first layer has a higher strength than the solid electrolyte layer.

摘要： Two active cell structures are prepared each comprising anode/electrolyte/cathode layers, each anode and cathode layer having embedded spaced-apart physical structures therein. Two interconnect sublayers are prepared, each comprising a layer of non-conductive material with holes formed therein and a conductor layer formed on one surface. The sublayers are placed together with the conductor layers in contact and with the holes offset to form an interconnect layer, which is then stacked between the two active cell structures. The multi-layer stack is laminated together and the anode layer of one active cell structure and the cathode layer of the other active cell structure fill the adjacent holes in the interconnect layer. The physical structures are pulled out to reveal embedded gas passages, and the multi-layer stack is sintered to form two active cells connected in series by the interconnect layer.
