CONTRIBUCIÓN A LA ELABORACIÓN DEL ÁNODO DE UNA CELDA DE COMBUSTIBLE DE ELECTROLITO SÓLIDO, COMO UNA FUENTE ALTERNA DE ENERGÍA ELÉCTRICA

Abstract

This thesis is focused on the elaboration of an anode for a solid oxide fuel cell, based on the lanthanum chromite, due to its properties like high electronic conductivity and stability to high temperatures, this powder offers great expectations in the use for fuel cell anode. Therefore, La0.8Sr0.2Cr0.95Ni0.05O3 type perovskite ceramic powders were preparared by two techniques: Sol Gel and Solid State Reaction, using almost the same conditions, like temperature and time of calcination. The resulting powders were examined via X-rays and scanning electron microscopy. Finally, two techniques were compared in order to know the best characteristics of each one for obtaining perovskita powder for the anode of a solid oxide fuel cell.
