Performance of Ba0.5Sr0.5Co0.8Fe0.2O3−δ/Ce0.85Sm0.15O2−δ–CuO as a cathode for intermediate temperature solid oxide fuel cells

Fundamental Understanding and Application of Ba0.5Sr0.5Co0.8Fe0.2O3−δPerovskite in Energy Storage and Conversion: Past, Present, and Future

“…The most appropriate amount of electrolyte material in the composite cathode prepared by physical mixing was demonstrated to be 30 wt % considering the electrode activity. ,− Although the cell performance with such composite cathodes was slightly improved or similar to that with pure BSCF cathode, because BSCF is already a high oxygen ionic conductor, good stability can be expected due to better thermal mechanical compatibility between cathode and electrolyte materials. The introduction of an appropriate amount of Ag or CuO to the BSCF + GDC (or BSCF + SDC) composite cathode could increase the electronic conductivity and ionic conductivity, respectively, thus dramatically improving the corresponding cell performance. Similar to pure BSCF cathode, the activity and stability of composite cathodes can be enhanced by morphology control, such as nanostructuring by impregnation and electrospinning − techniques.…”

Effect of cobalt and magnesium doping on the performance of Ba0.5Sr0.5Fe0.8O3 cathode for solid oxide fuel cell applications

“…In the literature, several doping agents were used to develop different cathode materials which include Sm 0.5 Sr 0.5 CoO 3 , LnBa 0.5 Sr 0.5 Co 2-x Fe x O 5+δ (x = 0, 0.25, 0.5, 0.75 and 1.0), SrCo 0.9 Nb 0.1 O 3-δ , Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O 3-δ (BSCF), Ca 2 Fe 2 O-Ce 0.9 Gd 0.1 O 1.95, (La 0.6 Sr 0.4 ) 0.9 Co 0.8 Fe 0.2 O 3-δ and BaCo 0.4 Fe 0.4 Zr 0.1 Y 0.1 O 3-δ [9][10][11][12][13][14][15][16]. From the reported literature, BSCF has demonstrated as a better cathode system with improved performance [17][18][19]. However, higher coefficient of thermal expansion (CTE) is a limitation with the Co containing BSCF system [20].…”

Comparative performance assessment of nano-composite cathode of LMSO-BSCMF for low temperature solid oxide fuel cell applications

“…Sm 0.5 Sr 0.5 CoO 3 [5], LnBa 0.5 Sr 0.5 Co 2-x Fe x O 5+δ (x = 0, 0.25, 0.5, 0.75 and 1.0) [6], SrCo 0.9 Nb 0.1 O 3-δ [7], Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O 3-δ (BSCF) [8], Ca 2 Fe 2 O--Ce 0.9 Gd 0.1 O 1.95 [9] and (La 0.6 Sr 0.4 ) 0.9 Co 0.8 Fe 0.2 O 3-δ [10] and BaCo 0.4 Fe 0.4 Zr 0.1 Y 0.1 O 3-δ [11] are a few examples can be found in the reported literature in developing low temperature SOFCs. The BSCF system as cathode material has shown more promising results in the available literature [12,13]. The presence of more cobalt (Co) in the BSCF cathode material increases the coefficient of thermal expansion (CTE) value, which is not suitable for low temperature SOFCs [14].…”
