Corrosion Study of Mesoporous Carbon Supports for Use in PEM Fuel Cells
Bibliographic record
Abstract
In this study, the corrosion resistance of two ordered, high surface area, mesoporous carbons (OMCs) were evaluated for PEM fuel cell applications, in comparison with microporous Vulcan carbon (VC). Using a hexagonal mesoporous silica as a hard template, the OMCs were synthesized using sucrose and anthracene as the carbon precursors, denoted as OMC-S and OMC-A, respectively. The corrosion testing protocol involved a potential cycling-step sequence between 1.4 V for 50 s and 0.8 V for 10 s, for a total of 18 cycles, all in room temperature 0.5 M H 2 SO 4 . The corrosion resistance of the carbons is found to be VC > OMC-A > OMC-S, which correlates with their degree of graphitization, as determined by X-ray diffraction and thermogravimetric analysis.

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.
