SOLID OXIDE FUEL CELL AND SOLID OXIDE FUEL CELL STACK

摘要

A solid oxide fuel cell that includes a power generation film including first and second electrode layers and a solid oxide electrolyte layer; first and second bases that define first and second gas flow channels; and a via-hole conductor unit connected to the first electrode layer. The via-hole conductor unit has a first via-hole conductor with a first end surface and a second via-hole conductor with a second end surface. The first end surface of the first via-hole conductor is in contact with the second end surface of the second via-hole conductor. A boundary part is between an outer peripheral edge of the first end surface of the first via-hole conductor and a part of the first base adjacent the outer peripheral edge are in contact with the second end surface 9a of the second via-hole conductor 9.

1. A solid oxide fuel cell comprising:
a power generation film comprising a solid oxide electrolyte layer with first and second principal surfaces, a first electrode layer on the first principal surface, and a second electrode layer on the second principal surface; a first ceramic base adjacent the first electrode layer of the power generation film and defining a first gas flow channel; a second ceramic base adjacent the second electrode layer of the power generation film and defining a second gas flow channel; and a via-hole conductor unit in the first ceramic base and connected to a surface of the first electrode layer, wherein the via-hole conductor unit has a first via-hole conductor with a first end surface and a second via-hole conductor with a second end surface, the first end surface of the first via-hole conductor in contact with the second end surface of the second via-hole conductor, the second end surface of the second via-hole conductor is larger in area than the first end surface of the first via-hole conductor, and a boundary part between an outer peripheral edge of the first end surface of the first via-hole conductor and a part of the first base adjacent the outer peripheral edge are in contact with the second end surface of the second via-hole conductor.
