000841667 520__ $$aCeria based ceramic materials have been widely used as solid oxide fuel cell (SOFC) components such as diffusion barriers, electrolytes, and electrode materials. Especially, in the case of anodes, excellent electro-catalytic activity is observed due to the mixed ionic and electronic conduction. This mixed conduction behavior is attributed to the oxygen-vacancy formation and diffusion associated with reversible Ce4+/Ce3+ transition. In the same way, the introduction of elements with multiple oxidation states to the ceria structure might enhance electronic conductivity, as well as catalytic activity. Mo6+ ions can be reduced to lower valence states (e.g Mo5+,4+,3+) which may increase further electronic conduction. Therefore, Mo-doped ceria was studied as SOFC anode materials. A series of Ce1-xMoxO2+δ (CMO) and Ce1-xGd0.1MoxO2+δ (CGMO), (x=0.05, 0.1, and 0.2) compositions were synthesized by conventional solid-state reaction and characterized by XRD and DTA-TG. The synthesized CMO and CGMO were than prepared as paste with NiO and applied to the cell using a screen printing process. However, the sintering of CMO and CGMO is limited due to the poor thermal stability caused by Mo doping. Because of this, an attempt was made to manufacture the cell using other processes (gas diffusion and thermal diffusion) and an electrolyte-supported structure. The presentation summarizes the study of Mo doped ceria materials from materials properties to applicability.
