Abstract
It is indicated that water can be an active motif for nanoparticle ex-solution. Yet, only a handful of studies are available, if possible, limited to the elemental composition of Ba(Co,Fe,Zr,Y)O 3−δ as a mother oxide. Here we prove the versatility of water-mediated ex-solution by expanding the perovskite palettes. Among these, our selected composition (i.e., Ag ex-solved Ba 0.95 Ag 0.05 Co 0.8 Nb 0.1 Ta 0.1 O 3-δ, e-BACNT) is demonstrated as an oxygen electrode material for protonic ceramic electrochemical cells, promoting efficient reversible fuel-power generation. Thereby, a peak power density of ∼1.81 W cm –2 and water-splitting current density of ∼2.93 A cm –2 at 1.3 V and 650 °C are achieved within a single cell. Apart from its notable cell performances, this work unveils new opportunities for creating functional metal-oxide heterointerfaces.

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 it
