讨论了微管状固体氧化物燃料电池（SOFC）的优点，包括增加的功率密度、快速启动和循环性能。几个国际发展进行了讨论，特别是小型便携式应用，这需要快速启动和多个周期。挤出是制造微管SOFC的主要方法，因为改善的结构和性能可以从组分颗粒的更好混合得到，并且共挤出可以在一个工艺步骤中集成几个电池组件。当管的直径< 3 mm时，示出了功率密度和抗热震性大大增加，在几秒钟内启动，而不是平面设计的几小时，如在丁烷上运行的单电池手持系统中所示。循环的问题，热和氧化还原，然后详细考虑。热循环降解遵循疲劳曲线，而氧化还原损伤与循环次数呈线性关系。新的结果提出的热和氧化还原循环性能。
The benefits of microtubular solid oxide fuel cells (SOFCs) are addressed, including increased power density, rapid start-up, and cycling performance. Several international developments are discussed, especially small portable applications, which demand fast start and multiple cycles. Extrusion is the main method for making microtubular SOFCs because improved structure and properties can result from better mixing of the component particles and coextrusion can integrate several cell components in one process step. When the tubes are < 3 mm in diameter, it is shown that the power density and thermal shock resistance are much increased, with start-up in a few seconds rather than hours for planar designs, as demonstrated in a single-cell hand-held system running on butane. The problems of cycling, both thermal and redox, are then considered in detail. Thermal cycling degradation follows a fatigue curve whereas redox damage is linear with the number of cycles. New results are presented on thermal and redox cycling performance.
