Evaluation of Metal Supported Ceria Based Solid Oxide Fuel Cell Fabricated by Wet Powder Spray and Sintering
Bibliographic record
Abstract
A ceria based solid oxide fuel cell was fabricated onto a porous stainless steel support by sintering process. The metal supported cell was composed of a porous AISI430 support, a Ni–Ce0.8Y0.2O1.9 anode, a Ce0.9Gd0.1O1.95 electrolyte, and a La0.6Sr0.4Co0.2Fe0.8O3 cathode. A cell was tested at 600°C for up to 2700 h on humidified argon balanced hydrogen and air. The cell showed no signs of degradation over 1200 h at low current densities of 0.16 and 0.24 A cm−2; however, under a high current density of 0.32 A cm−2, the cell voltage dropped by 25% in 1400 h. Impedance measurements showed a sharp increase in polarization resistance that could be associated with the cathode. Ohmic resistances from the oxide scale and electrodes did not significantly contribute to the overall resistance, while electrode polarization resistance accounted for more than half of the overall resistance.

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.
