Festoxid-Brennstoffzelle und Verfahren zu ihrer Herstellung

摘要

A solid oxide fuel cell comprising a hollow dense substrate having a plurality of mounting holes formed in the surface thereof, cell sections mounted in the mounting holes, and interconnections connecting adjacent cell sections, in which each cell section comprises: (1) a flat porous electrode base made of an electrode material for either of an air electrode and fuel electrode, an electrolyte film and the other porous electrode film in order in such a manner that the porous electrode base and the electrolyte film are exposed at one side of the forming surface; or (2) an electrode film made of an electrode material for either of an air electrode and fuel electrode, an electrolyte film, and the other electrode film on a flat porous support base in order in such a manner that the lower electrode film and the electrolyte film are exposed at one side of the forming surface. The cell are manufactured by mounting a plurality of previously-made cell sections in the mounting holes and connecting adjacent cell sections by interconnections.
