Abstract

A fuel cell includes an anode, a solid electrolyte layer, a barrier layer, and a cathode. The anode includes a transition metal and an oxygen ion conductive material. In the interface region within 3 micrometers from the interface with the solid electrolyte layer of the anode after reduction, the content rate of silicon is less than or equal to 200 ppm, the content rate of phosphorous is less than or equal to 50 ppm, the content rate of chromium is less than or equal to 100 ppm, the content rate of boron is less than or equal to 100 ppm, and the content rate of sulfur is less than or equal to 100 ppm.
