Abstract ：
Development of electrocatalytically active, durable hydrogen electrode materials is vital for solid oxide cells (SOCs). La0.75Sr0.25Cr0.5Mn0.5O3 (LSCM) hydrogen electrode shows great potential for durability in a harsh operational environment, although its practical application is critically limited by the low intrinsic electrocatalytic activity. Herein, a heterogeneous LSCM-Gd0.1Ce0.9O1.95 (GDC) nanocomposite hydrogen electrode is synthesized by coupling a self-assembly synthesis method with a sintering-free direct assembly technique. The self-assembly method gives rise to the formation of a nanocomposite with a robust LSCM-GDC heterointerface and increased surface oxygen vacancies. The direct assembly method enables preservation of the original nanostructure and heterointerface in the hydrogen electrode, and the subsequent electrochemical polarization induces in situ construction of a coherent electrode|electrolyte interface. A corresponding electrolyte-supported single cell achieves a peak power density of 1.04 W cm-2 and an electrolysis current density of 1.51 A cm-2@1.5 V in pure CO2 at 850 degrees C. The cell shows no noticeable degradation during 200 h galvanostatic test in fuel-cell and electrolysis modes. This work provides an innovative approach for the development of LSCM-GDC nanocomposite electrodes for efficient and durable SOCs.

Abstract ：
Thermally induced crystallization in sealing glass is one of the main factors in affecting their application in intermediate-temperature solid oxide fuel cells (IT-SOFCs). Herein, the influence of crystallization on the physical properties and sealing ability of BaO-MgO-Al2O3-B2O3-SiO2 (BMABS) glass are investigated. The results show that crystal phases, BaAl2Si2O8, BaMg2Si2O7, and Ba5Si8O21 are readily precipitated from the glass at a preannealing temperature of 750 degrees C, and the crystallinity reaches 44 % and 58 % after pre-annealing for 20 h and 100 h, respectively. Nevertheless, the physical properties of the pre-annealed BMABS glass fall into the requirements for IT-SOFCs. After pre-annealing at 750 degrees C for 100 h, the coefficient of thermal expansion of BMABS is 10.7 x 10-6 K-1, the electrical conductivity is 3.2 x 10- 7 S cm- 1 at 750 degrees C, and the self-healing ability is maintained. Moreover, the utilization of a stainless steel | BMABS glass | single cell sandwiched assembly assessment demonstrates excellent gas-tightness and intact sealing interfaces between the BMABS glass and adjacent components.

Abstract ：
Solid oxide cells (SOCs) are emerging devices for efficient energy storage and conversion. However, during SOC operation, gaseous chromium (Cr) species released from Fe-Cr alloy interconnect can lead to Cr deposition and poisoning of air electrodes, causing substantial degradation in electrochemical performance and compromising the longterm stability of SOCs. This mini-review examines the mechanism of Cr deposition and poisoning in air electrodes under both fuel-cell and electrolysis modes. Furthermore, emphasis is placed on the recent advancements in strategies to mitigate Cr poisoning, offering insights into the rational design and development of active and Cr-tolerant air electrodes for SOCs. © 2025 Science Press.

Abstract ：
The adoption of oxide precursor substrate can simplify the preparation process and reduce the cost of metal- supported solid oxide fuel cells (MS-SOFCs). However, the drastic shrinkage of oxide substrate during reduction can cause structural damage of MS-SOFCs. Herein, yttria-stabilized zirconia (YSZ) is incorporated to tailor the physical properties of NiFe substrate and structural stability of MS-SOFCs. The results show that the incorporation of YSZ phase leads to significantly suppressed sintering and grain growth during high temperature sintering and reduction processes as well as mitigated shrinkage of substrate and improved flatness of single cell during reduction process. The incorporation of YSZ phase also significantly enhances the mechanical strength and maintains acceptable electrical conductivity of the substrate. The single cell with the incorporation of 15 wt % YSZ phase into the NiFe substrate produces a peak power density of 1.02 W cm- 2 at 750 degrees C with no noticeable degradation during the galvanostatic test at 650 degrees C for 100 h. The present work provides a new strategy for the development of a NiFe metal substrate for robust MS-SOFCs.

Abstract ：
Solid oxide fuel cells, one of the most efficient energy conversion devices, are prone to performance degradation induced by cation surface segregation and chromium poisoning of cathodes. Herein, we enhance the chromium-tolerance of La0.6Sr0.4Co0.2Fe0.8O3–δ (LSCF) cathode by the regulation of surface strains through modification with a nanoscale, dual-phase coating. The coating is composed of a nanoscale BaCoO3−δ conformal film and BaCeO3 nanoparticles, and the strong interactions at BaCoO3−δ/LSCF and BaCeO3/LSCF heterointerfaces impose a compressive strain on the LSCF scaffold. The strain effect significantly suppresses the strontium surface segregation and thus mitigates the chromium attack on the cathode. Further, the microstructural and phase stabilities of the coating in volatile chromium environment also contribute to the long-term operational stability of the modified LSCF cathode. A single cell with the modified LSCF cathode demonstrates an excellent peak power density of 1.46 W cm−2 at 750 °C and remarkable chromium-durability in wet air. This work opens up a new route for suppressing strontium surface segregation and chromium-poisoning of the cathodes. © 2025 Elsevier B.V.

Abstract ：
Protonic ceramic fuel cells (PCFCs) are promising for efficient, clean energy conversion at low to intermediate temperatures, but the widely used BaZr0.1Ce0.7Y0.1Yb0.1O3-delta (BZCYYb) electrolyte has poor chemical stability in humid environments. Herein, we show that under oxygen reduction reaction (ORR) conditions, water accumulates at the BaGd0.8La0.2Co2O6-delta (BGLC) cathode-BZCYYb electrolyte interface, causing selective loss of Ba cations and decomposition of BZCYYb electrolyte. The introduction of triply ion-electron conducting La2Ce2O7-delta (LCeO) into the BGLC cathode expands its active reaction area, accelerates ORR kinetics, and suppresses water accumulation at the cathode-electrolyte interface and electrolyte decomposition. A single cell with the BGLC-LCeO composite cathode achieves a peak power density of 1.07 W cm(-2) at 700 degrees C, with no profound degradation at 0.5 A cm(-2) over 100 h. These findings provide guidance for the development of high-performance, durable PCFCs.

Abstract ：
Solid oxide cell (SOC) is a promising energy technology as they are capable of harmoniously and efficiently conversion of chemical and electrical energy. One of the important factors determining their efficiency and durability is the activity and stability of the electrodes and the electrode/electrolyte interface. In recent studies, sintering-free approach (SFA) have been developed for the in situ construction of electrodes, which preserve the nanostructure and high catalytic activity of the electrodes and enable the direct utilization of high-performance Co-containing electrodes on diverse electrolytes. Herein, research advances in the preparation of air electrodes, fuel electrodes, and both air and fuel electrodes by SFA are summarized, and the effects of polarization on electrode/electrolyte interface construction and interfacial elemental segregation are discussed. Both performance and stability are emphasized. Finally, the prospect of the SFA for the development of electrodes for SOCs with high catalytic activity and durability is discussed. © 2025

Abstract ：
Direct ammonia solid oxide fuel cells (DA-SOFCs) offer a promising pathway for the efficient utilization of carbon-free ammonia fuel. However, the nitridation of nickel-based cermet anodes in ammonia causes rapid microstructural coarsening, leading to durability problems. Herein, an efficient, ammonia-tolerant Fe-modified Ni-Gd0.1Ce0.9O1.95 (NiFe-GDC) nanocomposite anode is developed by coupling a self-assembly synthesis process with a sintering-free electrode fabrication technique. The as-synthesized nanocomposite oxides self-assemble into multiple phases, with GDC firmly grown on preformed NiO and NiFe2O4 nanoparticles, which are subsequently in situ alloyed in a reducing atmosphere to form a unique NiFe@GDC encapsulation structure with strong metal-oxide interactions. This NiFe-GDC nanocomposite not only provides abundant active sites for ammonia decomposition and electrochemical oxidation, but also exhibits exceptional resistance to nitridation and microstructural coarsening. Density functional theory calculations reveal that in situ-formed NiFe alloy lowers the energy barriers for ammonia adsorption and dehydrogenation while enhancing the nitrogen desorption process. An electrolyte-supported DA-SOFC with the NiFe-GDC nanocomposite anode achieves a peak power density of 0.61 W cm(-2) at 800 degrees C and exhibits outstanding operational stability for 100 h. This work offers new insights into the development of active and durable nickel-based nanocomposite anodes for DA-SOFCs.

Abstract ：
La0.9Sr0.1Ga0.8Mg0.2O3 (LSGM) with an extraordinary oxygen-ion conductivity has been extensively studied as an electrolyte material for intermediate temperature solid oxide cells (SOCs). However, the conventional hightemperature sintering process of electrodes results in detrimental reaction between LSGM and Ni-based hydrogen electrode and microstructural coarsening of the electrode. Herein, a buffer-layer-free LSGM electrolyte-supported single cell with a nanostructured Ni-Gd0.1Ce0.9O1.95 (GDC) electrode is developed using a sintering-free fabrication approach. The cell exhibits a peak power density of 1.23 W cm-2 at 800 degrees C and an electrolysis current density of 1.85 A cm-2 at 1.5 V with excellent operating stability. The good performance and durability is owing to the synergistic effects of the elimination of elemental interdiffusion at the electrode/ electrolyte interface, polarization induced in situ formation of hetero-interfaces between Ni-GDC and LSGM, and remarkable structural stability of Ni-GDC. This study provides an innovative means for the development of efficient and durable buffer-layer-free LSGM-supported SOCs.
