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 potion, 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.
