Anode with remarkable stability under conditions of extreme fuel starvation |
| 摘要 |
A solid oxide fuel cell (SOFC) includes a cathode electrode, a solid oxide electrolyte, and an anode electrode having a first portion and a second portion, such that the first portion is located between the electrolyte and the second portion. The anode electrode comprises a cermet comprising a nickel containing phase and a ceramic phase. The first portion of the anode electrode contains a lower porosity and a lower ratio of the nickel containing phase to the ceramic phase than the second portion of the anode electrode. |

1. A solid oxide fuel cell (SOFC), comprising:
a cathode electrode; a solid oxide electrolyte; and an anode electrode comprising a first portion comprising a cermet containing a nonzero volume percent of a nickel containing phase and a nonzero volume percent of a ceramic phase comprising doped ceria and a second portion comprising a cermet containing a nonzero volume percent of a nickel containing phase and a nonzero volume percent of a ceramic phase comprising doped ceria, such that the first portion is located between the electrolyte and the second portion; wherein: the SOFC is an electrolyte-supported SOFC and the first portion of the anode electrode contains a lower ratio of the nickel containing phase to the ceramic phase than the second portion of the anode electrode; the first portion of the anode electrode has a thickness of 3 to 30 microns; and the second portion of the anode electrode has a thickness of 3 to 30 microns.
