El objetivo del presente trabajo es evaluar las propiedades mecánicas, así como los diferentes mecanismos de fractura activados mediante ensayos de indentación instrumentada, de electrolitos basados en circona estabilizada con itria ("yttria stabilized zirconia",YSZ) y ceria dopada con gadolinia ("gadolinia doped ceria", GDC), para pilas de combustible de óxido sólido, SOFCs. Ambos materiales, con un espesor final de 200 ¿m, se conformaron mediante prensado uniaxial a 500 MPa y se sinterizaron a 1400ºC. Propiedades mecánicas tales como la dureza (H) y el módulo de Young (E) han sido estudiadas a diferentes profundidades de penetración utilizando el algoritmo de Oliver y Pharr.
