20140087282 | SOLID OXIDE FUEL CELL AND METHOD FOR PRODUCING SOLID OXIDE FUEL CELL - Provided is a solid oxide fuel cell comprising the following: a fuel gas flow path, a fuel electrode layer provided around the fuel gas flow path and containing an iron group element and a ceramic, a solid electrolyte layer provided around the fuel electrode layer, and an air electrode layer provided around the solid electrolyte layer. In a high-temperature state where the temperature of the solid oxide fuel cell, in which a fuel gas is supplied from one side of the fuel gas flow path and exhausted through an opening provided on the other side of the fuel gas flow path, is close to a power generation temperature, the solid oxide fuel cell is subjected to a process for regulating oxidation expansion rate of the fuel electrode layer, the oxidation expansion occurring when an oxidant gas flows in through the opening. As a result, it has become possible to provide a solid oxide fuel cell in which cracks in the electrolyte and cell breakage are prevented even when air flows into the fuel electrode side at the suspension of operations of the fuel cell. | 03-27-2014 |
20140308601 | METHOD FOR PRODUCING CERIUM-BASED COMPOSITE OXIDE, SOLID OXIDE FUEL CELL, AND FUEL CELL SYSTEM - On the other hand, the possibility of estimating the dopant ratio of a metal element to each ceria crystalline particle using integral-width or half-width obtained by XRD was considered as follows: an XRD peak is shifted depending on the dopant ratio of La to ceria; when La increases, an XRD peak is shifted to a lower angle; in XRD performed on a raw material obtained by mixing ceria crystalline particles having different dopant ratio, peaks corresponding to the respective dopant ratio exist close to each other; as a result, a peak width is widened; accordingly, the dopant ratio of a metal element to each ceria crystalline particles are supposed to vary when integral-width and half-width obtained by XRD are large. Thus, it was revealed for the first time that integral-width and half-width obtained by XRD indicate variations in dopant ratio. It should be noted that from the direct proportional relationship between the dopant ratio x and the integral-width for dopant ratio ranging from 0.35 to 0.45, integral-widths obtained by XRD are derived to be 0.10 to 0.30 for dopant ratio ranging from 0.35 to 0.45, and half-widths are derived to be 0.10 to 0.30 similarly. | 10-16-2014 |
