PURPOSE:To improve the output density per unit area and per unit volume of a vertical stripe cylindrical solid electrolyte fuel cell, to prevent a battery breakdown to generate a thermal stress, and to make the quality control and the manufacturing of the battery easier. CONSTITUTION:One single cell assembly 1 is to be composed by connecting a single cell 2 whose one end is closed and at least more than one of cylindrical single cells 3a, 3b,..., 3n whose both ends are opened, which have the size manufactured by utilizing the conventional manufacturing technology already established as it is. And the single cells 2, 3a, 3b,..., 3n to compose this single cell assembly 1 are preferably to have different cell areas each other and the cell areas are formed larger as separated farther from a fuel gas feeding port 27. Furthermore, at an oxidizer gas feeding pipe 6 and a fuel gas feeding pipe 5 provided at the inside and the outside of the single cell assembly 1, plural gas feeding holes 5a and 6a are provided to the feeding pipes 5 and 6 according to the lengths of the corresponding single cells 2, 3a, 3b,..., 3n, so as to feed the oxidizer gas and the fuel gas by distributing in the longitudinal direction of the single cell assembly 1. |
