Experimental Study of Current Collection in Single-Chamber Micro Solid Oxide Fuel Cells with Comblike Electrodes
Bibliographic record
Abstract
The effect of current collection on the performance of single-chamber micro solid oxide fuel cells with coplanar interdigitated, comblike electrodes was studied. Conventionally employed current collection on the electrode segment linking together the single lines of the electrode comb was compared to applying gold mesh current collectors on the whole electrode surface. A simplified design was used with a comblike Ni-YSZ (yttria-stabilized zirconia) anode on one side of the YSZ electrolyte and a square, planar cathode made of -YSZ and on the opposite side. The cells were tested in methane–air mixtures at . Current collection on the whole anode surface led to a reduction in the ohmic cell resistance for the conduction and collection of generated electrons, and 50% more power could be extracted from the cell. A nickel-rich anode with Ni content was investigated to enhance electron transport and conduction, but Ni instability in fuel–air mixtures prevented a performance increase. Additionally, the Ni-richer anode was more affected by aging. Collecting the current from the whole electrode surface area using suitable current collector designs will contribute to increasing the performance output of with comblike electrodes in the interdigitated configuration.

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.
