Porous 430L Stainless Steel as a Support Layer for Planar Solid Oxide Cells: Effect of Porosity on Mechanical Properties
Bibliographic record
Abstract
Porous 430L stainless steel components fabricated via tape casting underwent mechanical testing for potential in-vehicle application as mechanical supports of solid oxide cells. Tests included three-point bending up to 5% strain to assess flexural strength, yield strength, Young’s modulus, indentation hardness, and microstructural characterization. This study aimed to establish the relationship between pore former size and volume fraction and the resulting yield strength. It also compared sintered material without pore former, focusing on the influence of a wide range of porosity of up to 46.5%. The materials exhibited an inverse relationship for Young’s modulus, hardness and yield strength as a function of porosity. The lowest flexural yield strength obtained was approximately 120 MPa at the highest porosity of 46.5%, meeting the requirement of 59 MPa for the bipolar plates of existing proton-exchange membrane fuel cells.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
