PURPOSE:To improve the volume efficiency of a solid electrolyte cell by effectively utilizing a space with a unit cell made of a box type ceramic body and a spacer. CONSTITUTION:A gas guiding opening is provided on one face, the first electrode layers 2 are formed on all four outside faces in contact with this opening face, and a unit cell 7 made of a box type porous ceramic body 1 laminated in sequence with solid electrolyte layers 4 and the second electrode layers 5 on the three outside faces except one face among the four outside faces is provided. A spacer 8 made of nonconducting ceramic, having a gas guiding opening section and a U-shape, and overlapped on the unit cell so that the opening face of the unit cell and the opening section are made opposite in direction is provided. A space can be effectively utilized with the unit cell 7 made of box type ceramic and the U-shaped spacer 8. The fuel cell output for the unit volume can be made larger than that of the tubular type. |
