| 摘要 |
The present invention describes a solid oxide fuel cell (SOFC) or solid oxide electrolysis cell (SOEC) layered structure, said structure comprising a fuel electrode layer; an oxygen electrode layer; an electrolyte layer positioned in between the fuel electrode layer and the oxygen electrode layer; a support layer being attached to the fuel electrode layer and/or the oxygen electrode layer, said support layer being composed of a porous 3D backbone structure and a coated material covering the 3D backbone structure, wherein the 3D backbone structure of the support layer comprises a metal or metal alloy or a mixture of several metals and/or metal alloys and at least one toughened ceramic, and wherein the 3D backbone structure of the support layer is free from any metal exhibiting full reduction-oxidation (redox) transformation at cell operating temperature and conditions and free from any electro-catalytic ceramic or metal. The coated material on the 3D structure guarantees high temperature electrical conductivity sufficient for or superior to the needs for appropriate cell operation. |
