Data collection research project involving ionic migration/conductivity electroceramic electrolytes as used in solid oxide fuel cells (SOFC). Some of these papers derive from the industry involved, but the majority will likely come from academic studies. This project does NOT require researcher to characterize materials or conduct experimentation. This project is for collection of, and rapid means to navigate the appropriate papers. It does NOT require an analytical report.
Researcher will provide appropriate papers, and reference the materials’ characteristics as specified below via matrices/spreadsheet. Please pay special attention to alumina and materials that exhibit similar coefficients of expansion, as well as perovskites.
It involves compilation of a comprehensive (though perhaps not exhaustive) collection of published, peer-reviewed articles, and organization of the contained information in a spreadsheet (MS Excel preferred, but any compatible program acceptable) utilizing the following criteria for characteristics’ criteria:
1. Membrane material – electrolyte only (e.g. yttria stabilized zirconium, alumina, aluminum titrate, etc.)
2. Thickness of membrane film (in µm or nanometers.) We are principally interested in sub-micron scale.
3. Membrane surface area.
4. Sealants used.
6. Velocity of ionic migration through electrolyte membrane (Siemens per cm).
7. Velocity comparison (by order of magnitude) of stressed membrane to unstressed, bulk material (where available.)
8. Electrode materials used for both anode & cathode (e.g. Pt, Ru, Ni, Co, doped ceramics, etc.)
9. Working fluid (e.g. O, H, He, Ar, etc.)
10. Internal stress during operation (expansion)
11. Means of obtaining stress (where applicable.) e.g., differences in coefficient of expansion, piezoelectric tensions applied, etc.
12. Fabrication method used. Most, but not all, of these will involve ceramic casting of various sorts.
Such studies have been conducted for over ten years, and probably number ~50+, but could number several hundred. Ignore duplicate data. Researcher will present the articles themselves (PDF format please), and the above bullet-listed matrix criteria should reference to the articles (comment tags in Excel cells).
Researcher should have access to deep knowledge base in chemical engineering/materials science or related field.
