High Performance Direct Ammonia Fueled Solid Oxide Fuel Cells Based on Proton Conducting Solid Electrolytes
Bibliographic record
Abstract
The high performance anode supported single cells for ammonia fueled SOFCs, comprising of BSCF (Ba0.5Sr0.5Co0.8Fe0.2O3-δ)//BCY//NiO-BCY have been fabricated by wet colloidal spray for depositing 10-15 µm thin film electrolytes. The detailed characterization of BSCF, including electrical conductivities of sintered specimen as a function of temperature has been conducted to investigate the possibility to utilize BSCF as cathode for proton conducting electrolyte based cells. The electrochemical performance of single cells was characterized at the temperature 600-700 {degree sign}C under humid 75% H2 in N2 (3% H2O) as well as cracked ammonia as the fuel gas and air as the oxidant gas at a gas flow rate of 10-100 mL min-1. The open circuit voltages were around 1.05-1.08 V at 600 {degree sign}C indicating little gas leakage through the electrolyte. Maximum power density of 250 mW/cm2 was obtained at 600 {degree sign}C under air as the oxidant gas and humid 75% H2 in N2 (3% H2O) as the fuel gas at gas flow rates of 100 and 10 mL min-1, respectively.

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.
