Summary: In this study, nano-structured Sm0.5Sr0.5CoO3-(SSC) was infiltrated into the La0.6Sr0.4Co0.2Fe0.8O3-(LSCF)-Gd0.1Ce0.9O2-(GDC) electrode of a large-area flat-tube solid oxide cell for hydrogen production. The electrolysis current density only increased by approximately 3% at the thermal neutral voltage (1.29 V) and 750°C, but the electrolysis durability significantly improved by more than 90% with SSC infiltration. This study demonstrates that SSC infiltration can suppress Sr segregation and greatly enhance the cell durability, providing a reference for large-scale hydrogen production.

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: This study investigates the performance of lanthanum strontium chromite perovskite as a fuel electrode in steam electrolysis. The perovskite fuel electrode exhibits comparable performance to state-of-the-art Ni-CGO-based cells at higher temperatures, and even better performance at lower temperatures. The reaction mainly occurs on the oxygen vacancy sites on the perovskite surface, with the assistance of exsolved metallic Ni nanoparticles. However, a decrease in conductivity is observed over time, likely due to diffusion limitations. The lower activation energy of the perovskite fuel electrode holds promise for green hydrogen production via steam electrolysis at reduced temperatures.

Summary: Additive manufacturing techniques have been widely used to fabricate structural components with complex geometries. This study investigates the deformation behavior and irradiation damage of 316 L stainless steel fabricated by the direct energy deposition process. Results show that AM-induced features, like nanopores and sub-grain boundaries, could serve as defect sinks to absorb irradiation-induced defects, leading to improved void-swelling resistance and lower dislocation loop density compared to traditional manufacturing methods.

Summary: Irradiation response and deformation mechanisms of additively manufactured (AM) 316 L stainless steel were studied using atomic scale characterization and micro-pillar compression. The study revealed that manufacturing-induced pores hindered the deformation process, annealing reduced the material hardness, and irradiation resulted in significant twinning. Comparing the measured resolved shear stress with the predicted critical stress for dislocation dissociation, the study concluded that irradiation hardening was high enough to activate twinning. This research is important for optimizing the processing and evaluating the performance of AM alloys for reactor applications.
