摘要： PROBLEM TO BE SOLVED: To provide a high-temperature solid oxide fuel cell allowing replacement of a single piece of cylindrical cell wherein fuel or air is formed into a return flow type in the cell. SOLUTION: In this high-temperature solid oxide fuel cell, a tube for supplying fuel or air is inserted into a cylindrical electrolyte tube with one end closed from the end on the open side thereof, and the inserted tube is jointed to an electrode surface applied to the inside surface of the electrolyte tube by one or more electric conductive materials, whereby the electric conductive materials and the inserted tube surface part constitute a current collecting passage on the cell inside surface. The fuel cell is so structured that the fuel or the air supplied into the inserted tube is guided to the vicinity of the closed end of the electrolyte tube, thereafter enters an annular part formed between the inserted tube and the electrolyte tube, and flows toward the open end of the electrolyte tube in a direction opposite to the flow in the inserted tube; the unreacted fuel or air supplied to the inserted tube flows out to the outside of the cell; and hence the unit cell equipped with a structure for extracting a current from the inside and outside surfaces of the cell can individually be extracted.
