Nafion/Acid Functionalized Mesoporous Silica Nanocomposite Membrane for High Temperature PEMFCs
Bibliographic record
Abstract
This study reports the synthesis and the characterization of proton conducting composite membranes prepared by dispersing in Nafion matrix with highly acid functionalized mesoporous silica (KIT-6). Nafion/KIT-6 composite membranes were studied for operation in hydrogen/oxygen polymer electrolyte membrane fuel cells (PEMFC) at 120 {degree sign}C with different relative humidities (72%RH and 100%RH). The Nafion/KIT-6 composite membrane demonstrated little improved fuel cell performance to that of the Nafion membrane at 100% relative humidity (RH), however, it was much higher at low RH (72%). These results suggest that this new type of Nafion composite membrane may be successfully used as an improved proton exchange membrane in high temperature PEMFC.

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.
