Abstract
A solid oxide fuel cell (SOFC) includes a cathode electrode, a solid oxide electrolyte, and an anode electrode. The anode electrode includes a first portion made of a first anode material and a second portion made of a second anode material. The first anode material is a higher performance, lower oxidation resistant material than the second anode material.
