The invention provides a solid oxide fuel battery, comprising a cathode layer, an electrolyte layer, an inner anode layer and an outer anode layer, wherein the electrolyte layer is compounded on the cathode layer; the inner anode layer is compounded on the electrolyte layer; the outer anode layer is compounded on the inner anode layer; and the oxygen ion conductor material content of the inner anode layer is higher than that of the outer anode layer. The internal strength of the electrode is lower than the interface bonding strength of electrodes and electrolyte, and the outer anode layer generates cracks preferentially under the action of stress and releases stress, so that the effects of stress buffering and protecting interface bonding of the electrodes and the electrolyte are achieved. The electrode is of a three-dimensional porous structure, and the influence of the cracks in the electrode on the performance of the battery is obviously weaker than that of interface cracks, so that the stability of the battery is improved. In addition, the inner anode layer and the outer anode layer provided by the invention can be sintered together, so that the preparation process is simpler.
