520 _ _ |a The conventional Ni-yttria stabilized zirconia (YSZ) fuel electrodeshows strong degradation in SOEC operation under steam-containingfuels due to Ni migration and agglomeration. As an alternative,Ni-gadolinium doped ceria (GDC) electrode exhibit higherperformance than Ni-YSZ owing to the mixed ionic and electronicconductivity of GDC under reducing conditions, however it couldn’tprevent Ni-migration. To overcome these issues, we have consideredperovskites-based fuel electrodes, e.g. Sr2Fe2-xMox-yMyO6-δ (x=0.5, 1.0and M = Ni), as they exhibit mixed ionic and electronic conductingproperties and good redox stability under reducing atmospheres.SFM based fuel electrode materials also show higher electrochemicalperformances than Ni-YSZ electrode. Moreover, we have also investigatedNi-free fuel electrode materials and considered single-phaseceria-based materials e.g. Ce0.8Gd0.2O1.9 and Ce1-xPrxO2-δ (0.0 ≤ x ≤ 0.3).These ceria-based materials are mixed ionic and electronic conductorsand exhibit high catalytic activity under reducing atmospheres.For instance, the single cell with the GDC fuel electrode has similarperformance as that of the Ni-YSZ electrode but shows significantlylower degradation rates under SOEC operation. The structural, physicochemical,and electrochemical properties of newly developed fuelelectrodes including long-term degradation tests will be presented.
