Abstract
A fuel cell (10) includes an anode (11), a solid electrolyte layer (12), a barrier layer (13), and a cathode (14). The anode (11) includes a transition metal and an oxygen ion conductive material. In the interface region (R) within 3 micrometers from the interface with the solid electrolyte layer (12) of the anode (11) 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 chrome 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.
