开发用于运输的固体氧化物燃料电池、发电厂的底循环和电能的分布式发电的广泛努力是出于对更高的燃料效率和减少的空气污染的需要。引入氢作为燃料的障碍激发了人们对开发一种阳极材料的兴趣，该阳极材料可以在650 ℃ < T < 1000 ℃的工作温度下与天然气一起使用。在这里，我们报告了双钙钛矿Sr（2）Mg（1-x）Mn（x）MoO（6-delta）的鉴定，其满足长期稳定性的要求，具有耐硫性，并且在氢气和甲烷中显示出上级单电池性能。
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 Sr(2)Mg(1-x)Mn(x)MoO(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.
