  "textContent": "The electrochemical cell according to the present invention has an anode, a cathode, and a solid electrolyte layer disposed between the anode and the cathode. The cathode includes a solid electrolyte layer-side region within 3 μm from a surface on the solid electrolyte layer side. The solid electrolyte layer-side region has a main phase that is configured by a perovskite oxide, and a second phase that is configured by SrSOand (Co, Fe)O. The perovskite oxide is expressed by the general formula ABOand contains at least one of Sr and La at the A site. The (Co, Fe)Ocontained in the electrolyte layer-side region contains Co and Fe. An occupied surface area ratio of the second phase in a cross section of the solid electrolyte layer-side region is less than or equal to 10.5%.",
