SOFC CELL TUBE AND SOLID OXIDE TYPE FUEL BATTERY DEVICE

摘要

PROBLEM TO BE SOLVED: To enable continuous fuel supply to each power generation element and suppression of occurrence of instantaneous fuel lack in an SOFC cell tube having a single power generation element, particularly a cylindrical horizontal stripe type SOFC cell tube which is greatly affected by fuel lack.SOLUTION: In an SOFC cell tube in which plural horizontal stripe type power generation element parts are provided to a cylindrical support body so as to be arranged at predetermined intervals, the power generation element part includes at least a fuel electrode layer, a solid electrolyte layer and an air electrode layer which are arranged from the inside to the outside. The SOFC cell tube is provided with flow rate increasing means for increasing the flow rate of fuel gas to be passed through a passage in the cylinder and supplied to the fuel electrode layers of the power generation element parts.SELECTED DRAWING: Figure 1
