Abstract

A single cell was fabricated on a porous metal substrate prepared by the thermal reduction method. After reduction of NiO-Fe3O4 at 873 K for 5 h, porous metal substrate was successfully obtained. Thus obtained substrate had 30% porosity and ca. 15 cc/min H2 permeation rate, which is sufficient permeation rate for hydrogen. Pulsed laser ablation techniques were used for the preparation of LSGM films on top of the porous metal substrates. In order to prevent any reaction between Ni and LSGM, a thin film of SDC was deposited between the Ni-Fe substrate and the LSGM electrolyte. Sm0 5Sr0 5CoO3 was applied by the screen printing technique. Thus obtained SOFC showed almost the theoretical OCV and a maximum power density of 1.6 and 0.5 W/cm2 at 973 and 773 K, respectively.
