Shaping of ceria-based single solid oxide cells combining tape-casting, screen-printing and infiltration

Résumé

This study describes the development of a shaping process involving GDC10 (Ce0.9Gd0.1O1.95) as an electrolyte for Solid Oxide Cells operating at low temperature (500−600 °C). The goal is to build a single cell of porous/dense/porous GDC10 layers while adapting the porous layer thicknesses, which are infiltrated by catalysts to prepare efficient GDC-base composites. Two shaping processes were used to make the cell. The first process is die pressing of the electrolyte powder followed by the infiltration of a screen-printed porous backbone. The second shaping process consists of preparing a porous/dense/porous (30 μm/≈ 400 μm/30 μm) cell in a single step by combining tape-casting and screen-printing processes followed by the infiltration of the previous catalyst.
