Shrinkage Dynamics of Stainless Steel 430-L and Yittrium Stabilized Zirconia and Its Application in Co-Sintering for MS-SOFCs
Bibliographic record
Abstract
Metal supported-solid oxide fuel cells (MS-SOFCs), with metal as support in place of conventional ceramic support, are labelled third generation solid oxide fuel cells (SOFCs). In this paper, a detailed study of shrinkage behavior of stainless steel 430 L (SS-430 L) metal support and yittrium stabilized zirconia (YSZ) electrolyte is reported, in particular with regards to the effects of inert atmosphere, reducing atmosphere, and temperature ramping rates. In reducing atmosphere and at higher ramping rates (7.5 °C/min), SS-430 L shrinks earlier and to a higher extent than YSZ. Therefore, upon reaching sintering temperature of 1350°C, the SS-430 L layer is close to its maximum shrinkage, whereas YSZ layer is still sufficiently soft and continues to shrink leading to a flat cell without physical defects. On the other hand, sintering in inert atmosphere is not recommended because higher shrinkage of SS-430 L creates a significant mismatch in shrinkage of metal support and YSZ.

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.
