摘要

基于钡掺杂Sr2Fe1.5Mo0.5O6 (Sr2-xBaxFe1.5Mo0.5O6-?)其中x = 0.3, 0.5, 0.7和0.9)通过溶液燃烧法合成，并在1200℃下烧结。研究了它们的相组成、显微组织和电导率。结果表明，在450℃时，最大电导率为18.5 S/cm。测定了Sr1.3Ba0.7Fe1.5Mo0.5O6-?陶瓷。Sr2-xBaxFe1.5Mo0.5O6-?阴极与Gd0.2Ce0.8O1.9电解质的热膨胀系数匹配良好。

Novel cathode material for solid oxide fuel cells based on Ba-doped Sr2Fe1.5Mo0.5O6

Novel cathode materials for solid oxide fuel cells based on Ba-doped Sr2Fe1.5Mo0.5O6 (Sr2-xBaxFe1.5Mo0.5O6-? where x = 0.3, 0.5, 0.7 and 0.9) were synthesized by solution combustion method and sintered at 1200?C. Their phase composition, microstructure and electrical conductivity were studied. It was shown that the maximal electrical conductivity of 18.5 S/cm at 450?C was measured for the Sr1.3Ba0.7Fe1.5Mo0.5O6-? ceramics. The superior chemical compatibility between the Sr2-xBaxFe1.5Mo0.5O6-? cathode and Gd0.2Ce0.8O1.9 electrolyte was confirmed, as well as good matching between thermal expansion coefficients of the cathode and electrolyte materials.
