Oxygen-ion Transfer between YSZ/YSZ and YSZ/LSCF under Mechanical Contact Stress
نویسندگان
چکیده
The present study concerns oxygen-ion transfer between yttriastabilized zirconia single crystals (YSZ/YSZ) under mechanical contact stress. Two YSZ single crystal plates were piled up between platinum meshes, and contact stress was mechanically applied. The interfacial conductivity as well as the bulk conductivity was successfully measured with this setup. The interfacial conductivity is greatly influenced by the contact stress, whereas the bulk conductivity is almost independent of the stress. The interfacial conductivity was significantly increased with increasing contact stress. A similar improvement in the interfacial conductivity between YSZ and lanthanum strontium cobalt ferrite (YSZ/LSCF) was also observed.

Percolation Theory in Solid Oxide Fuel Cell Composite Electrodes with a Mixed Electronic and Ionic Conductor
Percolation theory is generalized to predict the effective properties of specific solid oxide fuel cell composite electrodes, which consist of a pure ion conducting material (e.g., YSZ or GDC) and a mixed electron and ion conducting material (e.g., LSCF, LSCM or CeO2). The investigated properties include the probabilities of an LSCF particle belonging to the electron and ion conducting paths, p...

We employed operando anomalous surface X-ray diffraction to investigate the buried interface between the cathode and the electrolyte of a model solid oxide fuel cell with atomic resolution. The cell was studied under different oxygen pressures at elevated temperatures and polarizations by external potential control. Making use of anomalous X-ray diffraction effects at the Y and Zr K-edges allow...
متن کاملYttria stabilised zirconia ( YSZ ) membranes and their applications By Chiao - Chien
Ceramic hollow-fibre membranes which have an asymmetric structure have been prepared in one step, using an immersion induced phase inversion technique. With this method, membranes with a high surface area per unit volume ratio can be produced, while production cost is dramatically reduced. Yttria-stabilised zirconia (YSZ) is selected as a membrane material, as it is relatively inexpensive and h...

The aim of this project was to begin the development of a new three-dimensional materials fabrication capability, Additive Layer Manufacturing (ALM).[1, 2] This initial 6 months of support allowed us to assess the feasibility of printing high-quality ceramic layers. In particular, a process was developed for printing layers of Yttria-Stabilized Zirconia (YSZ). This required the development of s...
متن کامل18O-tracer diffusion along nanoscaled Sc2O3/yttria stabilized zirconia (YSZ) multilayers: on the influence of strain
The oxygen tracer diffusion coefficient describing transport along nano-/microscaled YSZ/Sc2O3 multilayers as a function of the thick-ness of the ion-conducting YSZ layers has been measured by isotope exchange depth profiling (IEDP), using secondary ion mass spec-trometry (SIMS). The multilayer samples were prepared by pulsed laser deposition (PLD) on (0001) Al2O3 single crystalline substrates....
