The invention relates to a stack of electrochemical cells (10A, 10B), divided up into at least two groups (A, B), each cell comprising a distribution circuit for a reactive species, and each group of cells comprising a separate supply collector (2A; 2B). At least one cell (10B) comprises a homogenization compartment (60B) comprising: a plurality of longitudinal conduits (61B) designed to receive the flow of the reactive species coming from the supply collector (2B) of the corresponding group and to distribute it over the inlet (51B) of the distribution circuit for the cell; and, a transverse conduit (62B) for homogenization connecting the longitudinal conduits (61B) to one another in a fluid sense.

A method of forming an interlayer of a solid oxide cell unit on the surface of a substrate may include: providing a base interlayer solution comprising a solution of a soluble salt precursor of a metal oxide (crystalline) ceramic and crystalline nanoparticles, depositing the base interlayer solution onto the surface of the substrate, drying the base interlayer solution to define a nanocomposite sub-layer of the soluble salt precursor and nanoparticles, heating the sub-layer to decompose it and form a film of metal oxide comprising nanoparticles on the surface, and firing the substrate with the film on the metal surface, to form a nanocomposite crystalline layer.
