P (mN)
2) Nanomecanic characterization using Nanoindentation technique of different electrolytes in
SOFCs: YSZ (yttria stabilized zirconia), GDC (gadolinia doped ceria), and LSGM (lanthanum
strontium gallium magnesium oxide perovskite). Mechanical properties such as Young’s modulus
(E), hardness (H) and fracture toughness (K IC ), and the different fracture mechanisms induced
during indentation process, using Nanoindentation technique and atomic force microscopy
(AFM).

a) P-h curves (applied load versus indentation depth), corresponding to an indentation of GDC electrolyte, with
different changes of tendency (pop-ins) associated to the first stage of plastic deformation. B) AFM image of
GDC electrolyte with the fracture mechanisms (radial cracks).
