ABSTRACT:
A solid oxide fuel cell including a bottomprovided cylindrical solid oxide fuel cell element including at least an air electrode, a solid electrolyte and a fuel electrode, a gas feed pipe inserted into a cylindrical space and having a gas feeding portion for feeding an oxidizing gas or a fuel gas into the cylindrical space of the solid oxide fuel cell element. The gas feeding portion is provided at least in a lateral face of the gas feed pipe. 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.
