<P>PROBLEM TO BE SOLVED: To provide a power generation cell for a solid oxide fuel cell which exhibits good power generation performance even when the operation temperature is low (e.g. 600°C or lower), and can prevent warpage or cracking of the power generation cell. <P>SOLUTION: A power generation cell (1) for a solid oxide fuel cell comprises a solid electrolyte (2), an air electrode (3) formed on one main surface of the solid electrolyte, and a fuel electrode (4) formed on the other main surface of the solid electrolyte. The solid electrolyte has a first solid electrolyte (21) composed of (La,Sr)(Ti,Fe)O<SB POS="POST">3</SB>, and a plurality of second solid electrolytes (22) composed of an oxide having an oxide ion transport number of 0.96 or higher. An air electrode side second solid electrolyte is formed between one main surface of the first solid electrolyte and the air electrode, and a fuel electrode side second solid electrolyte is formed between the other main surface of the first solid electrolyte and the fuel electrode. <P>COPYRIGHT: (C)2012,JPO&INPIT |
