摘要： Provided are a solid oxide electrochemical cell with high power and a method for producing a solid oxide electrochemical cell by which a solid oxide electrochemical cell with high power can be fabricated in a manner that ensures both high productivity and high quality. A solid oxide electrochemical cell 10 includes a solid hydrogen electrode 12, a solid electrolyte membrane 14, and a solid oxygen electrode 16. The solid hydrogen electrode 12 includes, in a first surface 12f thereof, a plurality of first raised portions 12a raised in a direction toward the solid electrolyte membrane 14 and first intermediate portions 12b each located between two adjacent ones of the first raised portions 12a. The solid electrolyte membrane 14 includes second raised portions 14a stacked on the first raised portions 12a and second intermediate portions 14b stacked on the first intermediate portions 12b. The solid oxygen electrode 16 includes third raised portions 16a stacked on the second raised portions 14a and third intermediate portions 16b stacked on the second intermediate portions 14b. The first raised portions 12a have a pitch of 70 to 110 um. The second intermediate portions 14b are in contact with the third intermediate portions 16b without a gap therebetween.

摘要： A cell includes an element portion including a fuel electrode, a solid electrolyte layer, an air electrode, and an intermediate layer. The intermediate layer is located between the solid electrolyte layer and the air electrode. In a plan view, a porosity in an end portion of the air electrode is greater than a porosity in a center portion of the air electrode.

摘要： The present invention aims to provide a fuel battery system improved in reliability by accurately detecting when a fuel electrode gas or an air electrode gas has leaked. A fuel battery cell according to the present invention includes a first electrode, an electrolyte membrane, and a second electrode which are layered on a support substrate. Further, at least any one of the first electrode, the electrolyte membrane, and the second electrode is electrically isolated by an insulating member to form a first region and a second region. The insulating member is disposed at a position where the insulating member does not overlap with an opening portion of the support substrate
