PROBLEM TO BE SOLVED: To provide a solid oxide fuel battery cell which makes possible to maintain a high power generation performance.SOLUTION: A solid oxide fuel battery cell comprises a fuel electrode layer, an electrolyte layer including a zirconia based oxide, a reaction-preventing layer and an air electrode layer which are stacked in this order. The fuel electrode layer is arranged by stacking a first fuel electrode layer and a second fuel electrode layer from the side of the electrolyte layer in order. The first fuel electrode layer includes a zirconia based oxide and a conductive metal. The second fuel electrode layer includes a ceria based oxide, and a conductive metal.SELECTED DRAWING: Figure 1 【課題】高い発電性能を維持できる固体酸化物形燃料電池セルを提供する。【解決手段】固体酸化物形燃料電池セルは、燃料極層と、ジルコニア系酸化物からなる電解質層と、反応防止層と、空気極層とがこの順で積層され、燃料極層は電解質層側から第一の燃料極層、第二の燃料極層が順に積層されて構成され、第一の燃料極層はジルコニア系酸化物と導電性金属とを含んでなり、第二の燃料極層はセリア系酸化物と導電性金属とを含んでなる。【選択図】図１
