Extensive efforts to develop a solid-oxide fuel cell for transportation, the bottoming cycle of a power plant, and distributed generation of electric energy are motivated by a need for greater fuel efficiency and reduced air pollution. Barriers to the introduction of hydrogen as the fuel have stimulated interest in developing an anode material that can be used with natural gas under operating temperatures 650 degrees C < T < 1000 degrees C. Here we report identification of the double perovskites Sr2Mg(1-x)MnxMoO(6-delta) that meet the requirements for long-term stability with tolerance to sulfur and show a superior single-cell performance in hydrogen and methane.
为了提高燃料效率并减少空气污染，人们付出了巨大努力来开发用于交通运输、发电厂底循环以及分布式发电的固体氧化物燃料电池。将氢气作为燃料面临的障碍激发了人们对开发一种阳极材料的兴趣，这种材料能够在650℃ < T < 1000℃的工作温度下与天然气一起使用。在此，我们报告了双钙钛矿Sr2Mg(1-x)MnxMoO(6-δ)的鉴定结果，该双钙钛矿满足长期稳定性要求，耐硫，并且在氢气和甲烷中表现出优异的单电池性能。
