A solid oxide fuel cell comprises tube-shaped solid oxide fuel cell elements (1,2,3,4,5). One gas selected from an oxidizing gas and a fuel gas flows in an internal space (12) of an element, and the other gas flows in an external space of the element. Means (9,10) for converting an oxidizing gas-flow and/or a fuel gas-flow into turbulent flows is provided in the internal space and/or the external space. The converting means is preferably an elongated body such as a tube-shaped body, a solid pillar-shaped body, a hollow-cylindrical body, a solid-cylindrical body and a rod with plates, extending in the longitudinal direction of the element. More efficient use of the oxidizing gas and/or fuel gas can be achieved. <IMAGE> |
