A solid oxide fuel cell comprising a closed bottom cylindrical solid oxide fuel cell element including at least an air electrode (4), a solid electrolyte (6) and a fuel electrode (7), a gas feed pipe (1) inserted into a cylindrical space and having a gas feeding portion (2) for feeding an oxidizing gas or a fuel gas into the cylindrical space of the solid oxide fuel cell element. The gas feeding portion (2) is provided at least in a lateral face of the gas feed pipe (1). Instead of or in addition to the gas feeding portion being provided in the lateral face of the gas feed pipe, a permeating amount of the gas passing through that portion of the porous cylindrical support tube which faces an upstream side of a stream of the gas flowing through the cylindrical space is made smaller than that of the gas passing through that portion of the porous cylindrical support tube which faces a downstream side of the gas stream. <IMAGE> |
