“…Therefore, the development of cell materials and the optimization of the system structure of the low-concentration CBM-fueled SOFC are key research directions for the future. On the other hand, the research of cathode materials is also an important direction in which scholars are concerned. − The research of cathode materials has made some progress in recent years, and there has been a relevant review in this regard. − Furthermore, the scientific community has witnessed rapid advances in emerging materials, such as chalcogenides, which offer promising opportunities for developing anodes that exhibit improved stability and durability against carbon deposition and sulfur poisoning. Given the rapid advancement of material science research, the development of novel anode materials remains a critical research direction that holds significant potential for advancing SOFC technology in the future.…”

With the growing global demand for clean energy, more and more attention has been given to the energy conversion efficiency of low-quality fuels. A solid oxide fuel cell (SOFC) is expected to be one of the ideal technologies for clean and efficient utilization of low-concentration coalbed methane (CBM) because it can achieve efficient utilization of low-quality fuels. This review examines the challenges of SOFC technology fueled by low-concentration CBM. In comparison to fuels such as hydrogen and natural gas, lowconcentration CBM usually contains a large number of other gas components in addition to methane, which reduces the chemical reactivity of CBM and leads to a decrease in the utilization efficiency. The effects of different carbon-containing fuels on the cell performance of SOFC have been investigated by a great deal of research, and the results reveal that methane tends to be the main source of carbon deposition, whereas oxygen-containing fuels can have a positive effect on carbon deposition. In the current SOFC technology fueled by hydrocarbon fuels, concentration polarization is also a major factor contributing to the lack of durability and stability of the cell, with the exception of carbon deposition and sulfur poisoning. In addition, the temperature and other operating environments also have different degrees of influence on the cell performance in the SOFC technology fueled by low-concentration CBM. Therefore, the development of cell materials and the optimization of the system structure of a low-concentration CBM-fueled SOFC are still key research directions for the future.

“…[131] Thus, surface oxygen vacancies and transition metal ions within the ordered-structured DP oxides greatly affect oxygen adsorption and ORR activity. [132,133] Therefore, using these oxides as cathode materials in SOFCs could help improve their competitiveness in the energy market. However, the presence of other contaminated gases in ambient air such as CO 2 , and SO 2 may degrade these structures due to the possible reaction between contaminated gases with the alkali/alkaline earth metal oxides.…”

The high‐temperature solid oxide fuel cells (SOFCs) are the most efficient and green conversion technology for electricity generation from hydrogen‐based fuel as compared to conventional thermal power plants. Many efforts have been made to reduce the high operating temperature (>800 °C) to intermediate/low operating temperature (400 °C<T<800 °C) in SOFCs in order to extend their life span, thermal compatibility, cost‐effectiveness, and ease of fabrication. However, the major challenges in developing cathode materials for low/intermediate temperature SOFCs include structural stability, catalytic activity for oxygen adsorption and reduction, and tolerance against contaminants such as chromium, boron, and sulfur. This research aims to provide an updated review of the perovskite‐based state‐of‐the‐art cathode materials LaSrMnO3 (LSM) and LaSrCOFeO3 (LSCF), as well as the recent trending Ruddlesden‐Popper phase (RP) and double perovskite‐structured materials SOFCs technology. Our review highlights various strategies such as surface modification, codoping, infiltration/impregnation, and composites with fluorite phases to address the challenges related to LSM/LSCF‐based electrode materials and improve their electrocatalytic activity. Moreover, this study also offers insight into the electrochemical performance of the double perovskite oxides and Ruddlesden‐Popper phase materials as cathodes for SOFCs.

“…Due to layered structure, lower polarization resistances and higher catalytic activities of double perovskite (DP) and Ruddlesden-Popper (RP) , they are widely investigated as cathode materials for IT-SOFCs [7][8][9][10][11]. Cation-ordered LnBaCo2O5+d oxides have been paid more attention due to faster oxygen ion diffusion and higher electrical conductivity [12][13][14].…”

Three types of double perovskite La1-xPrxBa0.5Sr0.5Co1.5Fe0.5O5+δ(x=1,0.3,0) are prepared using the EDTA-citrate method and identified as solid oxide fuel cell (SOFC) cathodes. The microstructures, as well as electrochemical performances of La1-xPrxBa0.5Sr0.5Co1.5Fe0.5O5+δ (LPBSCF) and La2NiO4-impregnated LPBSCF (LN-LPBSCF) cathodes, are investigated in detail. An optimum impregnation amount of LN-LPBSCF (LN loading of 0.64 mg/cm2) electrode exhibits relatively lower electrode polarization resistance (Rp) and better stable performance as compared to that of pure LPBSCF electrode in symmetrical SOFCs. The maximum power density of LN-LPBSCF single cells is 800 mW/cm2 at 800 °C and demonstrates good stability for 100 h in short-term testing.
