Anode with remarkable stability under conditions of extreme fuel starvation

Abstract:

A solid oxide fuel cell (SOFC) includes a cathode electrode, a solid oxide electrolyte, and an anode electrode having a first region located adjacent to a fuel inlet and a second region located adjacent to a fuel outlet. The anode electrode includes a cermet having a nickel containing phase and a ceramic phase. The first region of the anode electrode contains a lower ratio of the nickel containing phase to the ceramic phase than the second region of the anode electrode.
