Effect of Nafion Loading in the Oxygen Electrode on Performance of the PEM-type Water Electrolyzer
Bibliographic record
Abstract
The electrocatalyst layers of the oxygen electrode with various Nafion loading for water electrolyzer with polymer electrolyte membrane (PEM-type) were prepared, and the relationship between Nafion loading in the oxygen electrode and the performance of PEM-type water electrolyzer were examined by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and Steady-state galvanostatic polarization (GP). It is found that the appropriate Nafion loading in the oxygen electrode (i.e., 0.5 and 1.0 mg/cm2) can increase the electrochemically active area and decrease resistance of electrocatalyst layer. The decrease in working voltage for water electrolyzer with 0.5 and 1.0 mg/cm2 Nafion loading was 0.23 and 0.19 V at a current density of 1A/cm2, compared with that of water electrolyzer without Nafion loading (2.25V).

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.
