    • PROBLEM TO BE SOLVED: To provide a solid oxide fuel battery cell having high initial power generation performance and good power generation durability performance while the adhesion between an air electrode layer and a current-collecting layer is ensured.SOLUTION: The solid oxide fuel battery cell has, at least, a solid electrolyte, a fuel electrode layer arranged on one surface of the electrolyte, an air electrode layer arranged on the other surface, and a current-collecting layer arranged on a surface of the air electrode layer. The air electrode layer is made of a material selected from the group consisting of a lanthanum ferrite-based perovskite oxide containing lanthanum and iron, a lanthanum cobalt-based perovskite oxide containing lanthanum and cobalt, and a samarium cobalt-based perovskite oxide containing samarium and cobalt. The current-collecting layer is composed of a porous layer containing silver, palladium, and an oxide. A portion of the current-collecting layer except a portion near an interface with the air layer has an average porosity between 20% and 70% inclusive. A portion of the current-collecting layer near the interface with the air electrode layer has an average porosity equal to or larger than 50% of the above average porosity.
