Abstract
The cost and durability of polymer electrolyte membrane fuel cell (PEMFC) systems have limited their deployment. The relative cost of the balance of plant (BOP) has risen in importance with decreasing fuel cell stack cost. Lowering costs of PEMFC system components require the understanding of potential contaminants from these materials. System contaminants have received very limited attention publicly. We here present ex-situ leaching tests with materials that could be considered as gasket materials to quickly screen BOP component materials. Aliquots of the leachant solutions were collected periodically and analyzed (pH, conductivity, etc.) to identify and quantify contaminants. The influence of the leachant on the electrochemical performance of Pt was also investigated.

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
