High-performance thin film solid oxide fuel cells with scandia-stabilized zirconia (ScSZ) thin film electrolyte

CuCo2O4‐Gd0.1Ce0.9O1.95 as a Potential Cathode Material for Intermediate Temperature Solid Oxide Fuel Cells

“…The CuCo 2 O 4 −GDC mixture in a weight ratio of 1:1 was calcined at 1200 °C for 6 h and the XRD pattern ofCuCo 2 O 4 −GDC mixture is shown in Figure a. As can be seen from Figure a, the CuCo 2 O 4 oxide crystallized in a cubic spinel structure with space group Pm‐3m and GDC crystallized in a cubic fluorite structure. After the CuCo 2 O 4 and GDC mixture had been calcined at 1200 °C for 6 h, the CuCo 2 O 4 and GDC samples still retained their own structures without any secondary phase and peak shift.…”

GDC-Based Infiltrated Electrodes for Solid Oxide Electrolyzer Cells (SOECs)

“…Then, the high operating temperature favors the kinetic at the electrodes and increases the overall efficiency of the cells [10]. Finally, SOECs can exploit all advantages of the development of solid oxide fuel cell (SOFC) materials [11][12][13] and technologies [14,15]. Therefore, extensive studies of SOECs and CO 2 electrolysis are largely available in the recent literature [1,16,17], as durable, stable, and efficient working electrodes for SOEC are greatly required.…”

Ridge‐Valley Nanostructured Samaria‐Doped Ceria Interlayer for Thermally Stable Cathode Interface in Low‐Temperature Solid Oxide Fuel Cell

“…SOFCs, however, usually operate at high temperatures (700–1000 °C) to retain adequate power output, which often leads to practical problems such as thermal stress or rapid material degradation. Many studies have been conducted with the aim to lower the operating temperature, in other words, to develop low‐temperature (<500 °C) SOFC (LT‐SOFC), by fabricating the cell with thin film components . In thin film electrolytes, which are employed in LT‐SOFC, the ohmic loss stemming from ionic transport inside the electrolyte is minimized, which means that the fuel cell performance is predominantly determined by the activation loss.…”
