In a stacked structure for forming a molten carbonate fuel cell according to the present invention, a plurality of unit cells are stacked, and separator elements are respectively interposed between the adjacent unit cells. First and second internal manifolds extend in the stacking direction, at both sides of the stacked structure. Third internal manifold extends at the center of the structure, in the direction of stacking. First fuel gas passages, communicating with the first and third internal manifolds, are formed at the anode side of the separator element. Second fuel gas passages, communicating with the second and third internal manifolds, are formed at the anode side of the separator element. Thus, the fuel gas flows through the first internal manifold, the first fuel gas passages and the third internal manifold, and the fuel gas flows through the second internal manifold, the second fuel gas passages and the third internal manifold. As a result, the current density distribution and the temperature distribution are uniform.
