Abstract
Mass transport phenomena under reduced RH were studied in H2/O2, air and heliox. IR corrected limiting current density and EIS were employed to identify the predominant transport mechanism at various RHs and current densities. It was found that the limiting current density decreased with increasing RH in H2/O2 fuel cell; EIS reveals that the low frequency arcs expand with increasing current density, but contract with increasing RH. The hydration-related low frequency arcs were hidden by gas phase diffusion arcs when operated under air or heliox. It was speculated that low frequency arcs are related to the dissolution and diffusion of reactant in the ionomer thin film. Under low RH operation, oxygen transport in the ionomer thin film within catalyst layer may become an important factor in cell voltage loss.

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
