| 摘要 |
The present invention provides an intermediate-temperature solid oxide fuel cell, comprising a ferritic stainless steel substrate including a coarsely porous support 3 and a non-porous frame housing 4 the coarsely porous support, a first electrode layer 5 located in the non-porous frame and supported internally by the coarsely porous support of the substrate, an electrolyte layer 6 located over the first electrode layer, and a second electrode layer 7 located over the electrolyte layer. The coarsely porous support is manufactured from expanded foil or woven mesh of ferritic stainless steel and, being bonded to the non-porous stainless steel frame, provides structural support for the fuel cells, collect electricity generated in the cells and allow the gas flow into the porous electrodes. The invention also provides a method of integrating the first electrode and the coarsely porous support into a composite support structure and a fabrication route which allows the sintering of the electrolyte into a dense impermeable layer over such supports at 1000{C or below. |
