Manufacturing of solid oxide fuel cell (SOFC) components remains nowadays a key point for the industrial development of this technology. Especially, the
deposition of the dense electrolyte layer which is sandwiched between the porous anode and the porous cathode is of paramount importance and thus focuses a lot of attention. Therefore, this paper considers and reviews recent developments concerning solid electrolyte layers manufacturing using thermal spray (TS) and physical vapour deposition (PVD) technologies.
