In-Situ Exsolution of Nano Transition Metal Particles on Lanthanum Chromite Perovskite Anode for Solid Oxide Fuel Cells
Bibliographic record
Abstract
The physical and electrochemical properties of lanthanum chromite perovskites in which a portion of Cr cations have been substituted with transition metals (La 0.6 Sr 0.3 Cr 0.85 M 0.15 , M= Ni, Fe, Co) were investigated and the suitability of the materials for use as anode in solid oxide fuel cell (SOFC) was assessed. The SEM results show that the well dispersed nano transition metal particles were successfully prepared by growing them in-situ directly from its perovskite parent backbone under anode reaction condition. And these particles can re-resolve into the lattice when exposed to oxidizing condition. The SOFCs exhibited desirable electrochemical performance in both sweet and sour fuels. It is demonstrated that the promoting effect should be attributed to the decoration of nano transition metals which enhanced the electronic conductivity and catalytic activity.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
