摘要：

Ultrasonic mist pyrolysis was applied to electrode preparation for a solid oxide fuel cell (SOFC) reactor. La1.8Al0.2O3 anode catalyst was prepared on heated YSZ substrate by the mist of aqueous solution containing lanthanum nitrate and aluminum nitrate generated by an ultrasonic transducer. The effect of spray times for periodic operation was investigated. Different anode catalyst structures were obtained by varying the spray time. These structures strongly affected the reactivity of oxidative coupling of methane. Short spray times gave thin layer structure of the anode catalyst which was suitable for this reaction.
