| 简介 |
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. |
