Development of 1 kW Class SOFC System at KEPRI
Bibliographic record
Abstract
Korea Electric Power Research Institute (KEPRI) is developing a SOFC system for a combined heat and power unit. KEPRI has studied an anode supported planar cell and a 1 kW class stack operated at intermediate temperature. A 1 kW class SOFC stack was composed of 37 cells with 10×10cm2 and stainless steel interconnects. It showed the maximum power density of 0.35 W/cm2 at 750{degree sign}C. When a 1 kW class SOFC system was operated at 750{degree sign}C with a reformate gas of city gas, the stack showed 1.13 kW electrical power at 40 A and 1.3 kW at 50 A respectively. Hot water was made by recuperated heat from combustion of unreacted anode off-gas and heat of 0.57-1.2 kW was recovered according to the loaded current.

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.
