Abstract
Abstract The present work deals with a poly(vinyl alcohol)‐based membrane mixed with poly(4‐styrenesulfonic acid) to be used as a proton‐conducting solid‐state electrolyte in an electrochemical gas sensor for the detection of alcohol. A cross‐linking bonding semi‐interpenetrating network is formed between the polymer backbones, providing the membrane with superior mechanical property and excellent water retention. Meanwhile, the graphene oxide nanosheets are incorporated into the polymer fibrous backbones, creating impermeable block layers to limit ethanol gas penetration. Importantly, the modification of graphene oxide facilitates the protons transportation in both in‐plane and through‐plane channels of the membrane, boosting excellent conductivities of 0.13 S cm −1 (in‐plane) and 22.6 mS cm −1 (through‐plane) at 75°C, respectively. An alcohol fuel cell sensor assembled with this semi‐interpenetrating network solid electrolyte membrane is fabricated based on direct ethanol fuel cell principle, exhibiting excellent sensitivity, linearity, as well as low ethanol detection limits of 25 ppm.

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 it
