Performance of Pd/C Cathode Electro-Catalysts for the ORR in Sulfuric Acid Containing Small Organic Molecules
Bibliographic record
Abstract
We studied the performance of carbon-supported Pd cathode electrocatalysts in O2-saturated acid solution containing ethanol. The Pd/C electrocatalysts showed an important selectivity toward the Oxygen Reduction Reaction (ORR), and a very high degree of tolerance to poisoning due to the presence of the alcohol. A negative shift in onset potential for the ORR of only 10 mV for a 20% Pd/C electrocatalyst in 0.5M H2SO4 + 0.125M C2H5OH electrolyte was measured, whereas the shift for a 20% Pt/C electrocatalyst was of 398 mV in the same solution. Similar high tolerances were established at increasing C2H5OH concentrations for Pd/C.

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.
