Impact of MPL Thickness on Water Management of PEMFC by Synchrotron X-ray Radiography
Bibliographic record
Abstract
Synchrotron X-ray radiography was utilized to visualize a miniature fuel cell with an active area of 0.48 cm 2 at an effective spatial resolution of 10 μm and 3 seconds per frame. Water in GDLs with MPL thicknesses of 0, 50, 100, 150 μm and 50 μm without a macro-substrate was quantified while the cell was operated at 0.5, 1.2 and 2.0 A/cm 2 . The presence of MPL significantly reduced water content at the interface between the catalyst and GDL. The thickness of MPL had trivial impact on water morphology in the GDL. In the perspective of water management, the GDL consisting of MPL without a macro-substrate can be effective as it produced the least amount of water.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
