Elaboration and interfacial reactivity of Lanthanum Strontium Chromium Ruthenium (LSCrRu) perovskite oxides as intermediate temperature fuel cell (ITSOFC) anodic compound
Bibliographic record
Abstract
Cette étude apporte des données sur l'intérêt des chromites de lanthane strontium dopés au ruthénium La1-xSrxCr1-yRuyO3 (LSCrRu) comme anode de pile à combustible ITSOFC. La synthèse sous champ micro-onde d'oxydes mixtes a permis la mise en forme de demi-cellules et cellules complètes modèles par pulvérisation cathodique magnétron et par sérigraphie. Les propriétés de reformage de CH4 ont pu être étudiées dans un dispositif mono-chambre couplé à un spectromètre de masse en collaboration avec l'Institut de REcherche Hydro-Québec. La réactivité à l'interface anode/électrolyte a été analysée par SIMS et XRD sur demi-cellules modèles vieillies sous H2 à 800C. Elle a permis de préciser la chimie du film après traitement. Les cellules complètes, testées en condition de fonctionnement, ont mis en évidence, après dissolution sélective de LSCrRu, une modification de la microstructure à l'interface anode/électrolyte. Des analyses XPS et SEM-EDX n'ont pas montré de réactivité chimique.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
