PROBLEM TO BE SOLVED: To provide a solid electrolytic fuel battery cell which can improve adherence strength of fuel poles to the solid electrolyte and maintain stable power efficiency over a long term. SOLUTION: In a solid electrolytic fuel battery cell formed by successive stacking of a solid electrolyte 31 and a fuel pole 33, having metallic particles 41 and ceramic particle 43 into the surface of an air pole 32, characterized in that a pit 45 is formed on the surface of the fuel pole part of the solid electrolyte 31. The metallic particles 41 of the fuel pole 33 are adhered to the surface of the solid electrolyte 31 adjacent to the pit 45, while the ceramic particles 43 of the fuel pole 33 are adhered to the inside of the pit 45 and the surface of the solid electrolyte 31 adjacent to the metal particles 41. The inside surface of the pit 45 is linked to the ceramic particles 43 placed on the surface of the solid electrolyte 31. |
