Abstract

fetched live from OpenAlex

Mass transport in the proton exchange membrane fuel cell is heavily impacted by deformation of the gas diffusion layer (GDL) due to the resultant changes of porosity and permeability. The effects of deformation, due to uneven compression, on water transport are investigated by using finite element analysis (FEA) and three-dimensional multi-component, multi-phase models. Numerical results indicate that clamping forces have a significant influence on water distribution in the membrane electrode assembly (MEA). Analysis of both membrane water content and liquid water content in the GDL and catalyst layer (CL) show that a higher clamping force helps retain water in the membrane on the anode side but leads to worse water flooding on the cathode side.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Teacher imitation

Not 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.
