LaNi1-xCoxO3-δ(x=0.4 to 0.7) cathodes for solid oxide fuel cells by infiltration

Abstract

Performance of LaNi 1-x Co x O 3−δ (LNC) (x=0.4 to 0.7) as a cathode in solid oxide fuel cell (SOFC) is evaluated. Symmetrical cathode/electrolyte/cathode cells for electrochemical testing are prepared by infiltration of yttria stabilized zirconia (YSZ) backbone with LNC solutions. It is showed that the cathode infiltrated with LaNi 0.5 Co 0.5 O 3−δ (LNC155) has the lowest polarization resistance and activation energy, 197 mΩ cm 2 at 600 °C and 0.91 eV, respectively. Therefore it is the most promising material of the LNC group for electrochemical applications. X-ray diffraction analysis revealed that none of the materials is single-phased after heat treatment at 800 °C as they contain residues of La 2 O 3 and La 2 NiO 4−δ
