Abstract
Abstract The development of non‐precious metal catalysts (NPMCs) that are practical for use at the cathode of polymer electrolyte membrane fuel cells (PEMFCs) would provide immense economic advantages, perpetuating the looming widespread commercialisation of these devices. NPMC materials with excellent activity towards the oxygen reduction, coupled with PEMFC performance approaching that of state‐of‐the‐art platinum catalysts brings this technology one step closer to practical application. Currently, the stability of these materials is still limited, and developing NPMC with excellent activity, performance and operational stability is the holy grail of PEMFC catalyst research. Fundamental knowledge available, along with recent progress made in this field of research will be the subject of this review paper.

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
