A Flow through Porous Electrode Cell Design for the All Vanadium Redox Flow Battery
Bibliographic record
Abstract
A new flow field using a flow-through design has been evaluated for the all vanadium redox flow batteries (VRB). By dividing the flow between flow-by and a portion of the flow going through the electrode, a significant improvement in the performance was obtained. A 5 cm 2 carbon paper (39AA SIGRACET) electrode was used, and the gap between the membrane and each electrode was 2 mm. A vanadium electrolyte system using mixed sulfuric and hydrochloric acid was used. Charging / discharging cycles were performed and compared with the flow-by design. The polarization curve was also compared for a range of states of charge and flow rate. Moreover, the influence of the concentration of vanadium electrolyte and flow rate on the coulombic, voltage, energy efficiency and the pressure drop were evaluated for the new cell design.

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.
