Abstract
Official abstract text for this publication.
An electrical connection material for solid oxide fuel cells, which is capable of preferred electrical connections. The electrical connection material includes a burn-out material-containing ceramic layer and a burn-out material-free ceramic layer stacked on the burn-out material-containing ceramic layer. The burn-out material-containing ceramic layer contains a conductive ceramic and a burn-out material.
First claim
Opening claim text (preview).
The invention claimed is: 1. A solid oxide fuel cell comprising: an electrical connection comprising, stacked in the following order, a first ceramic porous layer, a first ceramic dense layer, a second ceramic porous layer, a second ceramic dense layer, and a third ceramic porous layer, the first and second ceramic dense layers having a porosity lower than a porosity of the first, second and third ceramic porous layers; and a plurality of power generation cells electrically connected to each other via the electrical connection. 2. The solid oxide fuel cell according to claim 1 , wherein the first second and third ceramic porous layers have a porosity within a range of 20% to 90%. 3. The solid oxide fuel cell according to claim 2 , wherein the first and second ceramic dense layers have a porosity of 0% to 20%. 4. The solid oxide according to claim 1 , wherein the first and second ceramic dense layers have a porosity of 0% to 20%. 5. The solid oxide fuel cell according to claim 1 , wherein the first, second and third ceramic porous layers have a combined thickness in a range of 0.40 times to 0.92 times a thickness of the electrical connection. 6. The solid oxide fuel cell according to claim 1 , wherein the first ceramic porous layer comprises a first surface of the electrical connection, and the second ceramic porous layer comprises a second surface of the electrical connection opposite the first surface. 7. A solid oxide fuel cell module comprising the solid oxide fuel cell according to claim 1 .
