Advancing Direct Liquid Redox Fuel Cells: Mixed-Reactant and In Situ Regeneration Opportunities
Bibliographic record
Abstract
Two approaches pertaining to the direct liquid redox fuel cell (DLRFC) have been investigated and demonstrated: mixed-reactant operation and in situ regeneration of the redox couple. The former involves supplying a mixed methanol Fe2+/Fe3+ redox electrolyte to the selective carbon cathode of the DLRFC and supplying the fuel to the anode via methanol crossover. This approach has the potential to significantly improve the cost, compactness, and volumetric and gravimetric power densities of the cell. The latter in situ regeneration approach involves substituting the fuel supply with air to spontaneously reverse the direction of electron flow in a DLRFC, which eliminates the need for an auxiliary regeneration unit and reduces the overall cost and complexity of a DLRFC system. Both modes of DLRFC operation, discharge, and regeneration, produce power that is unique compared to conventional systems.

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.
