Résumé en anglais

The present study is focused on the development of simple and low cost preparation of GDC10 (Ce0,9Gd0,1O1,95) as electrolyte for Solid Oxide Cells operating at 600°C. The main goal is to shape a single cell with porous/dense/porous GDC10 layers, the porous layers being thereafter infiltrated by catalysts. Two shaping methods are used. In the first one the electrolyte powder is pressed, followed by the infiltration of a screen-printed porous backbone. Pr6O11 and Ni were infiltrated as catalysts on the oxygen and hydrogen side, respectively. In both cases, the polarization values measured at 600°C on symmetrical cells are very low. To further facilitate the preparation of the cell, a porous/dense/porous support is elaborated in one step using tape-casting, then infiltrated with catalysts. The goal being to obtain a dense GDC10 electrolyte with two porous GDC10 backbones at the same temperature. Electrochemical measurements either on symmetrical or single cells are described.< Réduire
