PROBLEM TO BE SOLVED: To provide a cylindrical solid electrolyte fuel cell which can prohibit cracking in the solid electrolyte by heat stress and enhance a power generation efficiency by reducing a maximum air hole diameter within the solid electrolyte and a thickness scattering. SOLUTION: In a cylindrical solid electrolyte fuel cell constituted by forming a porous of air pole 32 in one surface of the solid electrolyte 31 and a porous of fuel electrode 33 in other surface of it and synchronous burning the solid electrolyte 31 and the air electrode 32, the maximum air hole diameter within the solid electrolyte 31 is less than 15 μm and the thickness scattering of the solid electrolyte 31 is also less than 20 μm. |
