Abstract

A solid oxide electrochemical cell of an embodiment includes: a cathode; an anode; and an electrolyte layer interposed between the cathode and the anode, wherein a porous region exists in a layer form in a region with a depth of 50% or less of the electrolyte layer from an anode side surface toward the cathode in the electrolyte layer or between the electrolyte layer and the anode.

First claim

What is claimed is:

1. A solid oxide electrochemical cell comprising:
a first electrode;
a second electrode; and
an electrolyte layer interposed between the first electrode and the second electrode,
wherein a porous region exists in a layer form in a region with a depth of 50% or less of the electrolyte layer from a second electrode side surface toward the first electrode in the electrolyte layer or between the electrolyte layer and the second electrode,
the first electrod…
