Abstract
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 contains a main phase and a second phase. The main phase is configured with a perovskite oxide which is expressed by the general formula ABOand includes at least one of Sr and La at the A site. The second phase is configured with SrSOand (Co, Fe)O. An occupied surface area ratio of the second phase in a cross section of the cathode is less than or equal to 10.5%.
