Ethanol - Tolerant Pt-free Cathode Catalysts for the Alkaline Direct Ethanol Fuel Cell
Bibliographic record
Abstract
The structure and electrochemical activity of carbon supported Pt-free cathode catalysts (Ag/C, Mn3O4/C and AgMnO2/C) are investigated by means of transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD) and cyclic voltammetry (CV). The catalysts display ethanol-tolerance for the oxygen reduction reaction (ORR) in 0.1 M KOH electrolyte containing ethanol at different temperatures. Because crossover of ethanol from anode to cathode through the membrane can occur in alkaline direct ethanol fuel cells (ADEFCs), selectivity of the cathode catalyst is of high importance. AgMnO2/C catalyst exhibits the highest catalytic activity toward ORR in presence of alkaline electrolytes containing ethanol.

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.
