采用Ce1-−xNixO2-−-y单相混合氧化物离子-电子导电电化学催化剂，作为甲烷和乙醇中工作的氧化物离子导电电解液抗结焦固体氧化物燃料电池的阳极功能重整层。Ce1-−xNixO2-−氧化物在较低温度(550-650℃)下在各种燃料中的优异电池性能证明了其对燃料重整的高催化活性。阳极侧快速的氧离子流量和形成的水蒸气也有利于碳氢化合物的重整，从而提高电池的性能和长期稳定性。在650℃时，甲烷和乙醇的最大功率密度分别为415和271mW/cm−2。长期耐久运行，电压输出稳定，抗积碳性能显著提高。
A single phase mixed oxide ion-electron conducting electrochemical catalyst of Ce1−xNixO2−yis employed as an anode functional reformation layer for a coking-resistant solid oxide fuel cell (SOFC) based on oxide ion conducting electrolyte operated in methane and ethanol. The high catalytic activity of Ce1−xNixO2−yoxide for fuel reformation is demonstrated by the excellent cell performances in various fuels at relatively low temperatures (550–650 °C). The fast oxygen ions flux and formed steam at anode side are also found to be favorable for hydrocarbon reformation to promote the cell performance and long term stability. At 650 °C, maximum power densities of 415 and 271 mW cm−2are achieved in methane and ethanol respectively. The resistance against carbon deposition is significantly improved with stable voltage output in a long-term durability operation.
