V2O3 Anode Catalyst for Solid Oxide Fuel Cell using H2S-containing Hydrogen
Bibliographic record
Abstract
A new vanadium oxide based anode catalyst V2O3-YSZ was developed for the purpose of direct use of hydrogen sulfide-containing hydrogen in solid oxide fuel cell systems. H2S-containing hydrogen (H2 balanced with 5000 ppmv H2S) and air were used as anode and cathode feed gas, respectively. The V2O3-YSZ catalyst showed good catalytic activity for conversion of H2S-containing hydrogen in the SOFC systems. Current density over 450 mA/cm2 at 0.5 V and maximum power density of 160 mW/cm2 (at 400 mA/cm2) were obtained at 900åC. Conductivity tests showed that the V2O3 catalyst had good electronic conductivity in hydrogen atmosphere. XRD and XPS analysis showed that the new catalyst was stable in the environment of H2S-rich hydrogen, and this was confirmed experimentally in fuel cell tests.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
