A single cell (1) of fuel cell comprises: a solid electrolyte layer (2); an anode layer (3) that is laminated on a first surface of the solid electrolyte layer (2); a cathode layer (5) that is laminated on a second surface of the solid electrolyte layer (2) with an intermediate layer (4) being interposed therebetween; and a cathode layer-side collector layer (6) that is laminated on a second surface of the cathode layer (5), said second surface being on the reverse side of the solid electrolyte layer (2)-side surface. The cathode layer (5) is configured to contain an Sr-containing material that contains Sr. The cathode layer-side collector layer (6) is configured to contain an Sr-free material that does not contain Sr and/or a low-Sr-content material that contains less Sr than the Sr-containing material, and covers surfaces of the cathode layer (5) other than a first surface that is in contact with the intermediate layer (4). |
