“…Different approaches are used to improve the stability of doped CeO 2 in a reducing atmosphere and further enhance its conductivity. The focus of recent research is, for example, on triple-doped ceria-based materials such as Ce 1− x (La 1/3 Sm 1/3 Gd 1/3 ) x O 2−δ (LSG) [ 15 , 16 ], Ce 0.8 Sm 0.12 Pr 0.08 O 2−δ [ 17 ], Ce 0.8 Nd 0.18 Ca 0.02 O 1.89 [ 18 ], and Ce 0.83 Dy 0.14 Ca 0.03 O 1.90 [ 19 ]. GDC co-doped with rare earth elements (CeO 2 –8Gd 2 O 3 –2Eu 2 O 3 (Eu–GDC) and CeO 2 –8Gd 2 O 3 –2Nd 2 O 3 (Nd–GDC)) are synthesized and studied in [ 20 ].…”

“…Cerium(IV) oxide (CeO 2 ) based materials have found multiple applications in different industry fields, such as electronics [1,2], environmental protection [3,4], optics [4,5], catalysis [6][7][8][9][10] and clean energy [11,12], which is the reason why CeO 2 is receiving considerable interest of the scientific community, constantly increasing over the last decade. Particular attention has recently been devoted to the development of next-generation power production system -solid oxide fuel cells (SOFC), which present devices operating with a supply of fuel that can provide sustainable, environmentally-friendly and efficient energy conversion and electricity generation with superior lifetime for widespread necessities [11][12][13][14][15][16]. The yt-trium stabilized zirconia presents so far the most common reliable electrolyte material, considering its superior oxygen ion conductivity at high temperatures characteristic for conventional SOFC operation (800-1000 °C) [17,18].…”

“…However, such high working temperatures lead to several disadvantages referring to technical complications in the first place. Thermal breakdown and mismatch of cell components, reduction of reliability over time, thermal stresses affecting cell structure and integrity and limited choice of fabrication materials are some of them [15][16][17]20]. In addition, there are substantial financial issues concerning manufacturing and operation costs.…”
