Abstract: Disclosed is a solid oxide fuel battery cell having a high initial power generation performance and a good power generation durability while ensuring adhesion between an air electrode and a current collector. The solid oxide fuel battery cell includes a solid electrolyte, a fuel electrode, an air electrode, and a current collector provided on the surface of the air electrode, wherein the air electrode is formed of lanthanum ferrite perovskite oxides, lanthanum cobalt perovskite oxides, or samarium cobalt perovskite oxides, and the current collector is porous including silver, palladium, and an oxide and has an average porosity of 20% to 70% in a portion other than a portion near a boundary between the current collector and the air electrode and, in the near-boundary portion, an average porosity of not less than 50% of the average porosity of the portion other than the near-boundary portion.
