ABSTRACT:
An SOFC anode is provided, which is fabricated from ceria which has been mixed with a nickel oxide-magnesium oxide material to stabilize the nickel against coarsening during high temperature SOFC operation. With a starting material of NiO--MgO solid solution in a cement anode, the MgO will diffuse into zirconia and/or ceria at the appropriate firing temperature for the respective materials. Reduction of NiO in the anode with the fuel during cell operation will result in metallic Ni grains with a fine dispersion of MgO. The dispersion of MgO in Ni retards coarsening of nickel during the high temperature operation of the cell.
