“…However, when LSGM is used as an electrolyte, it reacts with the traditional Ni-YSZ electrode to form a heterophase that affects the conductivity. 114 Therefore, it can be combined with other electrolyte materials, such as GDC and SDC, to improve its performance. There are two main methods for combining LSGM and SDC/GDC.…”

“…Solid oxide fuel cells (SOFCs) are clean energy conversion devices capable of converting the chemical energy stored in fuels directly into electrical energy without being limited by the Carnot cycle, resulting in high energy conversion efficiency [1][2][3]. Since the operating temperature of SOFCs is usually higher than 600 °C, they have a wide range of fuel flexibility [4,5].…”

BaCe0.8Fe0.1Ni0.1O3-δ (BCFN) in perovskite structure is impregnated consecutively by BCFN solution and BCFN suspension into a phase-inversion prepared NiO-Gd0.1Ce0.9O2-δ (GDC) scaffold as an anode of solid oxide fuel cells (SOFCs) with on-cell dry reforming of CH4 (DRM). The whole pore surface of the scaffold is covered by small BCFN particles formed by BCFN solution impregnation; the large pores near the scaffold surface are filled by BCFN aerogels with a high specific surface area produced by BCFN suspension impregnation, acting as a catalytic layer for on-cell DRM.

“…[1][2][3] The greenhouse effect caused by the accumulation of CO 2 in the atmosphere has led to serious environmental problems, such as rising global average temperatures, thawing glaciers, and destroyed ecosystems. [4][5][6] To address this tricky problem, on the one hand, the use of fossil fuels must be strictly controlled; on the other hand, excess CO 2 is expected to be captured from the atmosphere and utilized as a raw material to produce economically valuable chemicals. [7,8] For instance, SOECs can electrochemically convert pure CO 2 into CO exclusively, while powered by renewable energy resources.…”

Solid oxide electrolysis cells (SOECs), displaying high current density and energy efficiency, have been proven to be an effective technique to electrochemically reduce CO2 into CO. However, the insufficiency of cathode activity and stability is a tricky problem to be addressed for SOECs. Hence, it is urgent to develop suitable cathode materials with excellent catalytic activity and stability for further practical application of SOECs. Herein, a reduced perovskite oxide, Pr0.35Sr0.6Fe0.7Cu0.2Mo0.1O3‐δ (PSFCM0.35), is developed as SOECs cathode to electrolyze CO2. After reduction in 10% H2/Ar, Cu and Fe nanoparticles are exsolved from the PSFCM0.35 lattice, resulting in a phase transformation from cubic perovskite to Ruddlesden–Popper (RP) perovskite with more oxygen vacancies. The exsolved metal nanoparticles are tightly attached to the perovskite substrate and afford more active sites to accelerate CO2 adsorption and dissociation on the cathode surface. The significantly strengthened CO2 adsorption capacity obtained after reduction is demonstrated by in situ Fourier transform‐infrared (FT‐IR) spectra. Symmetric cells with the reduced PSFCM0.35 (R‐PSFCM0.35) electrode exhibit a low polarization resistance of 0.43 Ω cm2 at 850 °C. Single electrolysis cells with the R‐PSFCM0.35 cathode display an outstanding current density of 2947 mA cm−2 at 850 °C and 1.6 V. In addition, the catalytic stability of the R‐PSFCM0.35 cathode is also proved by operating at 800 °C with an applied constant current density of 600 mA cm−2 for 100 h.
