Abstract
Cell of a solid-oxide fuel cell that comprises a ferritic support (2), a first electrode (3) deposited on said ferritic support, an electrolyte (4) deposited on said first electrode (3), and a second electrode (5) deposited on said electrolyte (4). The cell comprises, between the first electrode (3) and the ferritic support (2), a diffusion barrier (6) that comprises cerium oxide.
