Abstract
A cell includes an element portion that includes: a fuel electrode; a solid electrolyte layer; an air electrode; and an intermediate layer located between the solid electrolyte layer and the air electrode. The solid electrolyte layer or the intermediate layer includes: a first site; and a second site that is located closer to the air electrode or closer to a center part of the element portion than the first site and that has a smaller porosity or a lower density than the first site.
Claims10
A cell comprising
- an element portion, the element portion comprising:
- a fuel electrode;
- a solid electrolyte layer;
- an air electrode;
- and
- an intermediate layer located between the solid electrolyte layer and the air electrode, the intermediate layer comprising:
- a first site;
- and
- a second site that is located closer to the air electrode or closer to a center part of the element portion than the first site and that has a smaller porosity than the first site, wherein
- in an overlapped region of the air electrode and the intermediate layer, the porosity of the intermediate layer in the outer peripheral part of the intermediate layer is greater than the porosity of the intermediate layer in the center part.
