Abstract
A fuel cell comprises an anode, a cathode, and a solid electrolyte layer disposed between the anode and the cathode. The solid electrolyte layer contains a zirconia-based material as a main component. A first intensity ratio of tetragonal crystal zirconia to cubic crystal zirconia in a Raman spectrum in a central portion of the solid electrolyte layer is greater than a second intensity ratio of tetragonal crystal zirconia to cubic crystal zirconia in a Raman spectrum of an outer edge.
