摘要:
A method for production of a solid oxide fuel cell (SOFC) (1), having an electrolyte body (10) with a tubular structure, wherein at least one internal electrode (11) and one external electrode (12) are applied to the tubular electrolyte body, with the method having at least the following steps: provision of an injection molding core (13) on which at least one interconnector material (14) and the internal electrode (11) are mounted, arrangement of the injection molding core (13) in an injection mold (25a, 25b), injection molding of an electrolyte compound (10a) in order to form the electrolyte body (10), and removal of the injection molding core (13) in the form of a casting process with a lost core.
摘要:
A composite body made of at least two ceramic layers, in which the ceramic layers are permanently bonded to one another at defined bonding points by a contact layer made of a bonding material. To achieve a permanent, thermally stable bond of ceramic layers having different coefficients of thermal expansion, the bonding material has a low modulus of elasticity. During the manufacture of the composite body, the bonding points of the ceramic layers are pretreated to form a porous surface structure, the bonding material is applied to these bonding points, and after the ceramic layers are laid one on top of another with bonding points facing toward one another and bonding material lying between them, the assembled composite body is subjected to a heat treatment.
摘要:
A method for manufacturing a component having a through-connection. The method includes providing a semiconductor substrate, forming a recess in the semiconductor substrate, and introducing into the recess a pourable starting material which has a metal. The method furthermore includes carrying out a heating process, an electrically conductive structure forming the through-connection being developed from the pourable starting material.
摘要:
A green ceramic insert having a green ceramic body provided with a recess extending through the ceramic body is provided, the recess being filled with a paste which may be converted into an electrical plated hole. A ceramic insert made from a sintered green ceramic insert of this type is also described. In addition, a ceramic green body or a green body composite is provided, which has at least one recess in some areas, into which one of the described green ceramic inserts is inserted. The ceramic insert may be integrally joined to the laminated composite, a conductive paste converted by sintering into a printed conductor being routed on the laminated composite in a manner electrically insulated from it, and electroconductively connecting the top of the laminated composite to its bottom via the electrical plated hole.
