Abstract
A solid electrolyte fuel cell with various improved features has been described. The cell comprises many unit cells each having a structure in which there are laminated a gas-permeable oxygen electrode made from an electron-conducting material, a solid electrolyte consisting of a (CeO.sub.2).sub.1-x (CaO).sub.x (x=0.05 to 0.8) binary system or a third component-containing (CeO.sub.2).sub.1-x (CaO).sub.x (x=0.05 to 0.8) system and a gas-permeable fuel electrode made from an electron-conducting material on a gas-permeable support, many unit cells being connected to each other in series with interconnectors by subjecting end portions of the electrolytes to a masking treatment or the like.
