      abstract     = {Ceria 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.},
