Summary: Scandia-stabilized zirconia (ScSZ) has higher conductivity compared to yttria stabilized zirconia (YSZ), but undergoes phase structure transition, affecting stability in SOFC applications. 10Sc1CeSZ, a commonly doped ScSZ, experiences Ce4+ - Ce3+ transition, resulting in lower fracture strength. Co-dopants such as Nd, Sm, and Gd show promise in enhancing the stability of ScSZ in reduced SOFC environments.

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: Metal-supported solid oxide cells with YSZ electrolytes fabricated by atmospheric plasma spraying often have OCVs below the Nernst potential due to gas crossover and combustion resulting from electrolyte defects. YSZ electrolytes were fabricated at high substrate temperatures and velocities to improve splat bonding and reduce coating defects. The cells exhibited permeabilities in the range of 4-6 x 10(-19) m(2) and the maximum recorded OCV was approximately 26 mV below the Nernst potential. The ohmic resistance decreased and the polarization resistance increased over time, indicating possible cell degradation mechanisms observed during short-term durability testing.

Summary: The Cu-Ti coating with varying copper content showed influence on its micro-galvanic dissolution behavior and antifouling performance, with higher copper content leading to increased copper ions release rate and antifouling duration against bacterial survival. Electrochemical tests revealed that the amount of micro-galvanic cells, rather than the dissolution rate of each single micro-cell, played a more prominent role in deciding the total copper dissolution rate and antifouling capabilities.

Summary: In this study, the oxidation kinetics of 430L porous support in PMS-SOFCs was investigated, showing a 1% mass gain after 500 hours of exposure at 650 degrees C due to the formation of a continuous Cr2O3 scale. Diffusion of elements across the interface of the anode and support was hindered by thin and continuous scales, with less than 1 µm thickness after 500 hours of oxidation. The decrease in maximum power density after 500 hours of oxidation was attributed to the formation of a continuous Cr2O3 scale and an increase in ohmic and polarization resistance.

Summary: SULC technology has great potential in underwater in-situ manufacturing/remanufacturing, allowing for the preparation of iron-based planar coatings with solidification structure distribution. The size and stability of the local dry region above the deposition point is influenced by the powder-feeding gas flow rate, while the laser power and powder-feeding rate are key factors in compensating for energy dissipation. Due to the local temperature gradient in SULC, the coating exhibits distinct solidification structure distribution.
