Summary: In this study, an innovative La0.6Sr0.4CoO3 (LSC) nanostructured air electrode with superior catalytic activity and exceptional robustness against delamination-induced degradation at the interface is reported. The LSC air electrode, decorated onto a porosity graded Gd0.1Ce0.9O2 backbone through ultrasonic-assisted infiltration, demonstrated significantly improved oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) kinetics, leading to prolific electrochemical performance compared to conventional LSC air electrodes. The fuel cell mode achieved a maximum power density of 2.24 W cm(-2), while the electrolysis mode achieved a maximum current density of 4.57 A cm(-2) at an operating voltage of 1.6 V at 750 degrees C. Remarkable durability was observed through reversible cycling and galvanostatic stability tests, attributed to the elimination of detrimental O-2 pressure at the air electrode/electrolyte interface. This study presents a highly durable SOC design for the production of green hydrogen and electricity, showcasing one of the highest performance levels to date.

Summary: A multiscale model was used to optimize the microstructure of a classical hydrogen electrode made of nickel and yttria-stabilized zirconia (Ni-8YSZ). Synthetic microstructures with different Ni/8YSZ ratios and Ni particle sizes were generated and analyzed to understand their impact on the electrode and cell responses. Results showed that decreasing the Ni particle size distribution significantly improved performance, and an optimum electrode composition was identified to minimize cell polarization resistance. These findings provide valuable insights for understanding the role of microstructure in cell performances and guiding cell manufacturing.

Summary: The microstructure instability of nickel-stabilized zirconia fuel electrode in solid oxide fuel cells (SOFCs) and solid oxide electrolysis cells (SOECs) is a challenge for commercialization. In this study, operando observations were conducted to study the mobility of nickel on the YSZ surface under different operation modes. The results showed that nickel phase dynamically spreads and splits up only under the SOFC mode, while this phenomenon is not observed under the SOEC mode. Nickel coarsening occurs regardless of the operation mode.

Summary: Since the proposal of high configurational entropy-driven structural stability of multicomponent oxide system in 2015, there has been significant progress in developing new multicomponent oxides. However, high configurational entropy oxide systems with more than 3 distinct cation sites have not been achieved. In this study, a multicomponent proton-conducting oxide system was successfully synthesized, demonstrating improved chemical stability towards CO2 without a significant decrement of the proton conductivity as the number of added elements increased.

Summary: Here, we report a highly conductive, robust, and innovative Gd and Pr multi-doped ceria (GPDC) coating to enhance the ORR kinetics and stability against Cr poisoning of the state-of-the-art LSCF cathode. The GPDC coating significantly improves the ORR kinetics by improving the surface of the LSCF cathode and shows a two-fold increase in electrochemical performance compared to the bare LSCF cathode. It also exhibits outstanding stability in an accelerated Cr poisoning test, attributed to the alleviation of SrCrO4 formation. Both relaxation time-based analysis and experimental results confirm that the GPDC coating enhances the ORR activity and Cr tolerance of the LSCF cathode.

Summary: Researchers have developed a new infiltration agent to manufacture high-performing air electrodes with nanostructures for solid oxide fuel cells, which can potentially reduce the operating temperature. The new process involves the thermal decomposition of trichloroacetic acid in water, causing metal ions in the solution to crystallize out as slightly soluble carbonates. This eliminates the need for high-temperature calcination after each infiltration step, resulting in improved performance and durability during stability tests.

Summary: Solid oxide fuel cells (SOFCs) are efficient and environmentally friendly energy conversion devices. However, their commercialization has been hindered by the lack of long-term durability. Cathode degradation and inter-diffusion of electrolyte and cathode materials have been identified as the main factors contributing to performance degradation. Cobalt-based perovskite materials, commonly used in SOFCs, offer favorable reduction kinetics but suffer from rapid degradation. Various elements accumulate or deposit at the electrode-electrolyte interface, leading to sluggish reaction kinetics and cell deterioration. Preventative and protective measures, such as novel fabrication techniques and addition of thin films, have improved the long-term stability of cobalt-based SOFC cathodes. This review paper summarizes the leading mechanisms of cobaltite cathode degradation and discusses strategies for enhancing the durability of cobalt-based SOFC cathodes.

Summary: Hexagonal perovskite-related oxides have attracted significant attention for their potential applications in electrochemical devices. This study reveals the anisotropic characteristics of proton conduction behavior in a Ba5Er2Al2ZrO13 (BEAZ) hexagonal perovskite electrolyte-supported cell. By controlling the orientation of the grains in the BEAZ thin film, the researchers demonstrate that proton migration is more favorable in the lateral direction than in the vertical direction. Density functional theory calculations and ab initio molecular dynamics simulations suggest that anisotropic proton migration is preferred through the perovskite-like layer.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
