A solid oxide fuel cell comprises a solid electrolyte layer, a barrier layer, and a cathode. The cathode includes a cathode current collecting layer and a cathode active layer. The cathode active layer includes a plurality of micro-cracks in a surface region within a predetermined distance from the interface between the barrier layer and the cathode active layer.
