Porous/dense La0.8Sr0.2Ga0.8Mg0.2O3-delta (LSGM) bilayer infiltrated with metallic oxidation catalyst

La0.8Sr0.2Ga0.8Mg0.2O3-delta (LSGM) perovskite oxide was selected as electrolyte to fabricate reduced-temperature solid oxide fuel cells (SOFCs). Porous/dense ceramic bilayers were optimized by using different pore forming agents. Reduced temperature (700 degrees C) infiltration method was employed to obtain anodes with nano-sized metal oxidation catalysts. The type and amount of porogen necessary to get a proper anodic porosity were evaluated together with the amount of infiltrated Ni catalyst to obtain promising electrochemical results.
