A Ferric-Air Battery base on Solid Oxide Fuel Cell for Electrical Energy Storage
Bibliographic record
Abstract
We report a ferric-air, solid oxide battery that consists of a tubular solid oxide cell with Ca(OH)2/CaO dispersed Fe/FeOx powders integrated as the redox-active materials in the fuel chamber. The key feature here is the use of Ca(OH)2 to prevent agglomeration and coarsening of Fe/FeOx powders, and more importantly to enable in situ production of H2/H2O as the electrochemical active redox couple in the fuel electrode. The proof-of-concept solid oxide battery exhibits an energy capacity of 144 Wh kg-1-Fe at a ferric utilization of 18.8% and excellent stability in ten discharge/charge cycles with a voltage efficiency of 83% that have great potential for improvement. These results showed encouraging promise of the ferric-air, solid oxide batteries for electrical energy storage applications.

How this classification was reachedexpand
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.
