Processing and characterizations of a novel proton-conducting BaCe0.35Zr0.50Y0.15O3-δ electrolyte and its nickel-based anode composite for anode-supported IT-SOFC
Bibliographic record
Abstract
This work presents the synthesis and characterizations of a stable and well-sinterable proton conductor BaCe 0.35 Zr 0.50 Y 0.15 O 3-δ in which a transition of conductivity occurred steeply from the order of 10 −3 to 10 −2 S cm −1 and activation energy changed from 0.35 to 0.22 eV in the temperature range from 350 to 400 °C, due to the dissociation of protons from the dopant-proton defect pairs. The anode composite Ni-BaCe 0.35 Zr 0.50 Y 0.15 O 3-δ (40:60 vol%) prepared by liquid condensation process showed comparatively very high electrical conductivity than the existing solid oxide fuel cell (SOFC) anodes, in the temperature range of 350–800 °C. Fabrication (by screen printing and co-firing processes), performance and post-mortem analysis of anode-supported protonic SOFC cell using these materials are discussed elaborately.

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.
