SUBSTRATE TUBE CONNECTION STRUCTURE FOR FUEL BATTERY, SUBSTRATE TUBE, AND MANUFACTURING METHOD OF SUBSTRATE TUBE

摘要

PROBLEM TO BE SOLVED: To provide a substrate tube connection structure for a fuel battery which achieves performance improvement of a fuel battery while maintaining the strength, and to provide a substrate tube and a manufacturing method of the substrate tube.SOLUTION: A substrate tube connection structure for a fuel battery includes: a substrate tube body 5 formed by a porous ceramic; a metal plate 10 in which a hole part H, into which the substrate tube body 5 is inserted, is formed; a seal ring 6 which is disposed between an outer peripheral surface of the substrate tube body 5 and the hole part H of the metal plate 10 and formed only by a ceramic; and an adhesion layer 7 disposed between the substrate tube body 5 and the seal ring 6 and bonding the substrate tube body 5 to the seal ring 6.SELECTED DRAWING: Figure 2
