【Abstract】 Ni/La(Sr)MnO3 used as anode for methane oxidation in SOFCs was prepared., DTA and TGA were applied to study the preparation conditions of the anode materials. The crystal structure, element composites and morphology of Ni/La(Sr>MnOs were determined by XRD. EDS and SEM, respectively. The conductivity of Ni/La(Sr)MnO3 was measured and compared with that of porous- Ni/ZrO2-Y2O3 cermets. The factors which effected on the conductivity of the anode materials were analysed.更多还原
