Abstract
A solid oxide fuel cell includes a one end-closed cylindrical porous air electrode tube, a solid electrolyte film provided on the outer periphery of the air electrode tube, and a fuel electrode film provided on the outer surface of the solid electrolyte film. A fuel gas is caused to flow around the outer periphery of the fuel electrode film, and an oxidizing gas is supplied into the inner space of the cylindrical air electrode tube to generate electric power. The pore diameter of that portion of the porous air electrode which is in contact with the solid electrolyte film is smaller than that of the surface portion of the porous air electrode on the side opposite to the interface.
