The interface region and inner region respectively include rod-shaped crystal particles that have three or more aspect ratios when viewed in cross section. An average orientation angle of the rod-shaped crystal particles included in the interface region is greater than or equal to 60 degrees and less than or equal to 120 degrees. A standard deviation of the orientation angle of the rod-shaped crystal particles included in the inner region is greater than a standard deviation of the orientation angle of the rod-shaped crystal particles included in the interface region.

摘要： An electrochemical cell stack includes a first separator, a second separator, and an electrochemical cell disposed between the first separator and the second separator. The electrochemical cell includes an anode, a cathode and a solid electrolyte layer. The solid electrolyte layer is disposed between the anode and the cathode and contains zirconia-based material as a main component. The solid electrolyte layer has an upstream part and a downstream part. The upstream part is positioned on the upstream side in the flow direction of fuel gas that flows in the fuel flow passage between the anode and the first separator. The downstream part is positioned on the downstream side in the flow direction. The upstream part includes a first region within 3 μm from the anode side surface, and a second region provided on the first region. An intensity ratio of tetragonal zirconia to cubic zirconia in a Raman spectrum of the first region is greater than an intensity ratio of tetragonal zirconia to cubic zirconia in a Raman spectrum of the second region.

The cathode contains a main component configured by a perovskite oxide which is expressed by the general formula ABO3 and includes at least Sr at the A site. The solid electrolyte layer is disposed between the anode and the cathode. The cathode has a surface region and an inner region. The surface region is within 5 μm from a surface opposite the solid electrolyte layer. The inner region is formed on a solid electrolyte layer side of the surface region. The surface region and the inner region respectively include a main phase configured by the perovskite oxide and a secondary phase configured by strontium sulfate. An occupied surface area ratio of the secondary phase in a cross section of the surface region is greater than an occupied surface area ratio of the secondary phase in a cross section of the inner region.

摘要： A second mold is placed on a planar surface of a first mold to form a first mold cavity, which is filled with a first material slurry containing a first material powder and the molded slurry is caused to set, thereby forming a first molded part on the planar surface of the first mold. A third mold is placed on the planar surface of the first mold from which the second mold is removed and on which the first molded part is formed, thereby forming a second mold cavity. The second mold cavity is filled with a second material slurry which contains a second material powder different from the first material powder so as to mold the slurry in contact with the first molded part. The molded slurry is caused to set, thereby forming a second molded part on the planar surface of the first mold.
