PURPOSE:To prevent the output increase per unit volume and the cell breakage of thermal stress, by integrating a fuel manifold with an air manifold to form a box vessel, and mounting a fuel cell vertically thereto. CONSTITUTION:A fuel manifold 35 and an air manifold 36 are integrated and formed into a box vessel. For example, cylindrical cells 31 are mounted in such a manner that their axial directions are vertical to the box vessel. As the cylindrical cells 31 are supported by the box vessel, they can be formed without any support pipe, and thus a number of miniature ones can be closely disposed, resulting in an increase in output per unit volume of cell. The fuel and air are sent in the same direction through a box manifold. Thus, the temperature during operation is changed only in the axial direction of the cell, and the thermal expansion is released in the axial direction of the cell, so that the cell breakage of thermal stress can be prevented. |
