摘要： 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 SrSO4 and (Co, Fe)3O4. The perovskite oxide is expressed by the general formula ABO3 and contains at least one of Sr and La at the A site. The (Co, Fe)3O4 contained 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%.
