Abstract
Provided is a solid oxide fuel cell including a flat-plate-shaped cell structure including a cathode, an anode, and an electrolyte layer containing a solid oxide, a frame-shaped sealing member disposed so as to surround a periphery of the cathode, the sealing member having a larger outside diameter than the cathode, a first pressing member and a second pressing member that hold the sealing member therebetween, and a flat-plate-shaped cathode current collector adjacent to the cathode, the flat-plate-shaped cathode current collector being formed of a porous metal body having a three-dimensional mesh-like skeleton, in which the cathode current collector has a peripheral portion that is not opposite the anode, the outer edge portion of a main surface of the sealing member adjacent to the anode faces the first pressing member, the inner edge portion of the main surface of the sealing member adjacent to the anode faces the peripheral portion of the electrolyte layer, the outer edge portion of a main surface of the sealing member opposite the main surface of the sealing member adjacent to the anode is opposite the second pressing member with the peripheral portion of the cathode current collector, and the inner edge portion of the main surface of the sealing member opposite the main surface of the sealing member adjacent to the anode faces the body portion of the cathode current collector other than the peripheral portion of the cathode current collector.
