Abstract
A sealing structure of a cell tube for a tubular type fuel cell has a sealed portion composed of a conductive lead film formed on a surface of a substrate tube, and an airtight film with high airtight properties formed on a surface of the lead film. The sealing structure also has an adhesion enhancing film provided on a surface of the airtight film, and a sealing member adhered to a surface of the adhesion enhancing film via an inorganic adhesive coated on the surface of the adhesion enhancing film. Thus, the sealability of the cell tube is increased, and the electrical characteristics of the fuel cell are improved.
