Nanoporous Silicon-Based Direct Hydrochloric Acid Fuel Cells
Bibliographic record
Abstract
Fabrication and characterization of Au/Porous silicon/Silicon (Au/PS/Si)-type direct hydrochloric acid fuel cells have been presented in this work. The Au/PS/Si cells were prepared by first creating the nanoporous silicon layer in single-crystalline Si using the anodic etching under illumination and deposition Au catalyst layer onto the porous silicon. The porous silicon filled with hydrochloric acid was developed as a proton conducting membrane. Using HCl:H2O (1.7 M) solution as fuel the open circuit voltage of 0.65 V was obtained and maximum power density of 3.5 mW/cm2 at room temperature was achieved. It is shown that the Au/PS/Si-type direct hydrochloric acid fuel cell with gold catalyst operating at room temperature can be considered as the most promising type of low cost fuel cell for small power-supply units.

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.
