Abstract

See full text

A solid oxide fuel cell (SOFC) includes a cathode electrode, a solid oxide electrolyte and an anode electrode containing a first portion having a cermet containing a nonzero volume percent of a nickel containing phase and a nonzero volume percent of a ceramic phase and a second portion having a cermet containing a nonzero volume percent of a nickel containing phase and a nonzero volume percent of a ceramic phase, such that the first portion is located between the electrolyte and the second portion. 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 porosity of 5-30 volume percent and the second portion of the anode electrode has a porosity of 31-60 volume percent.
