520 _ _ |a Ni- yttria-stabilized zirconia is commonly used as a fuel electrode cermet in solid oxide cells due to its compelling combination of conductivity, stability, and material compatibility. However, it faces significant degradation when exposed to hydrocarbon-rich fuels, such as tar-containing biogas. Carbon adsorption poisons the Ni component, leading to a decrease in catalytic activity, while the formation of carbon fibers ultimately results in nickel dusting. To address the issue of fuel electrode degradation without the need for fuel pre-treatment, this study investigates two alternative fuel electrode materials. The first material is gadolinia-doped ceria (Gd0.1Ce0.9O2-δ) as a replacement for yttria-stabilized zirconia. Gadolinia-doped ceria possesses mixed electronic and ionic conductivity, allowing it to maintain catalytic activity even when Ni is poisoned. Moreover, it exhibits oxygen storage capacity, potentially aiding in carbon removal. ...
