Title: Electrical and hydrogen reduction enhances kinetics in doped zirconia and ceria: II . Mapping electrode polarization and vacancy condensation in YSZ

Abstract

Abstract Knowing the correlation between grain boundary mobility and oxygen potential in yttria‐stabilized zirconia ( YSZ ), we have utilized the grain size as a microstructural marker to map local oxygen potential. Abrupt oxygen potential transition is established under a large current density and in thicker samples. Cathodically depressed oxygen potential can be easily triggered by poor electrode kinetics or in an oxygen‐lean environment. Widespread cavitation in the presence of highly reducing oxygen potential suggests oxygen vacancy condensation instead of oxygen bubble formation as commonly assumed for solid oxide fuel/electrolysis cells. These results also suggest electrode kinetics has a direct influence on the microstructure and properties of ceramics sintered under a large electric current.

Electric-Loading Enhanced Kinetics in Oxide Ceramics: Pore Migration, Sintering and Grain Growth: Final Report

Technical Report Chen, I-Wei

Solid oxide fuel cells and solid oxide electrolysis cells rely on solid electrolytes in which a large ionic current dominates. This project was initiated to investigate microstructural changes in such devices under electrochemical forces, because nominally insignificant processes may couple to the large ionic current to yield non-equilibrium phenomena that alter the microstructure. Our studies had focused on yttria-stabilized cubic zirconia (YSZ) widely used in these devices. The experiments have revealed enhanced grain growth at higher temperatures, pore and gas bubble migration at all temperatures, and the latter also lead to enhanced sintering of highly porous ceramics into fully densemore »« less

Emergence and Extinction of a New Phase During On–Off Experiments Related to Flash Sintering of 3 YSZ

Journal Article Lebrun, Jean‐Marie ; Morrissey, Timothy G. ; Francis, John S. C. ; ... - Journal of the American Ceramic Society

The flash phenomenon occurs when oxide ceramics are heated above a threshold temperature under an applied electric field. It is defined as an abrupt increase in the conductivity of the specimen. The specimen then can be held in this state of high conductivity by switching the power supply from voltage to current control. Here, we report on the emergence of new X‐ray diffraction peaks in 3 mol% yttria‐stabilized zirconia (3 YSZ ) when the specimen is held in this current controlled state. These peaks are indexed as a pseudocubic phase of zirconia. The peaks extinguish and reappear when the field ismore »« less

Mobility transition at grain boundaries in two‐step sintered 8 mol% yttria‐stabilized zirconia

Journal Article Dong, Yanhao ; Chen, I‐Wei - Journal of the American Ceramic Society

Abstract Stagnation of grain growth is often attributed to impurity segregation, which becomes more severe as the grain size grows. In this respect, there is no evidence for segregation‐induced slowdown in the grain growth of yttria‐stabilized cubic zirconia, which obeys the parabolic law when the size increases by more than ten times. However, lowering the temperature below 1300°C triggers an abrupt slowdown, constraining the average grains to grow by less than 0.5 μm in 1000 hours despite a relatively large driving force imparted in the fine grains of ~0.5 μm. Yet isolated pockets of abnormally large grains, and even most remarkably, pockets ofmore »« less

The Detection of Monoclinic Zirconia and Non-Uniform 3D Crystallographic Strain in a Re-Oxidized Ni-YSZ Solid Oxide Fuel Cell Anode

Journal Article Heenan, Thomas M. ; Vamvakeros, Antonis ; Tan, Chun ; ... - Crystals

The solid oxide fuel cell (SOFC) anode is often composed of nickel (Ni) and yttria-stabilized zirconia (YSZ). The yttria is added in small quantities (e.g., 8 mol %) to maintain the crystallographic structure throughout the operating temperatures (e.g., room-temperature to >800 °C). The YSZ skeleton provides a constraining structural support that inhibits degradation mechanisms such as Ni agglomeration and thermal expansion miss-match between the anode and electrolyte layers. Within this structure, the Ni is deposited in the oxide form and then reduced during start-up; however, exposure to oxygen (e.g., during gasket failure) readily re-oxidizes the Ni back to NiO, impedingmore »« less

Freeze-cast yttria-stabilized zirconia pore networks: Effects of alcohol additives

Journal Article Miller, Sarah M. ; Xiao, Xianghui ; Setlock, John A. ; ... - International Journal of Applied Ceramic Technology

Abstract Freeze casting yttria‐stabilized zirconia ( YSZ ) can be useful in making electrodes for solid oxide fuel cells ( SOFC s) by introducing hierarchical porosity to increase triple‐phase boundary ( TPB ) area while maintaining adequate fuel flow. In this study the influence of alcohol additives on pore structure of aqueous YSZ freeze‐cast samples was investigated. Slurries with ethanol, iso‐propyl alcohol, or methanol as additives were compared to a control sample. Pore characteristics along sample lengths were measured using X‐ray computed tomography reconstructions. The control sample showed significant changes in pore size along sample length, whereas pore size ofmore »« less
