Abstract

fetched live from OpenAlex

Abstract A design approach of extending the anode zone for miniaturization of the fuel cells was investigated in an air‐breathing micro‐direct methanol fuel cell (µDMFC) with an extended anode catalyst region on the walls of the fuel flow channel. This non‐conventional design is demonstrated to be a feasible approach to enhance the volumetric power density of a micro‐direct methanol fuel cell by increasing the total anode catalyst amount without affecting the cell dimensions. The fuel cell with extra anode catalyst on the fuel channel walls improves the maximum power density of a micro‐fuel cell by at least 20% compared to the conventional design with only a catalyst coated membrane (CCM). The effects of key operating conditions on the overall cell and individual electrode performances are examined. The mass transport of methanol to the catalyst active sites is more efficient in the fuel cell with anode catalyst on both the membrane and channel walls than the conventional fuel cell design with anode catalyst only on the membrane.

Full frame distilled prediction

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.
