Abstract

Doped lanthanum gallate (La_1-xSr_x)(Ga _1-y-zMg_yCo_z)O_3-(x+y+z)/2 (LSGMCO) perovskite oxide films were deposited on a quartz glass, LaAlO₃ single-crystal substrate and porous anode electrode of a solid oxide fuel cell (SOFC) by pulsed laser deposition. It was necessary to increase the substrate temperature up to 800°C for a crystallization of the LSGMCO films. The film deposited on the LaAlO₃ single-crystal substrate grew along the e-axis. The as-deposited LSGMCO thick film fabricated on the porous substrate at 800°C and at an oxygen pressure of 20Pa was formed from polycrystal columns and showed a high conductivity of 0.75/cm at a measurement temperature of 800°C. The activation energies were 0.72 eV at 600-800°C and 1.05eVat400-600°C.
