Fuel Cell Studies on a Non-Noble Metal Catalyst Prepared by a Template-Assisted Synthesis Route
Bibliographic record
Abstract
The catalytic activity of a templated catalyst material (Fe–N–C), prepared using , pyrrole, and a mesoporous silica gel as template, was investigated. The oxygen reduction reaction activity of the catalyst material was measured using the rotating ring-disk electrode technique, revealing an onset potential of about 0.85 V vs a reversible hydrogen electrode. The catalytic activity of the prepared sample was also tested in a fuel cell for different catalyst loadings using oxygen or air atmospheres. Fuel cell polarization measurements were recorded at . The power densities varied between 0.032 and for different catalyst loadings when oxygen was used. In addition, durability tests were carried out by keeping the cell at 0.6 V for 16 h. The current densities decayed to about 25% of the initial value during this period. The results are compared to state-of-the-art results from the literature. The templated catalyst shows comparable activity to the best catalysts in the literature but its durability requires improvement.

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.
