采用相转化、浸渍涂层和高温共烧相结合的方法，将电极催化剂浸渍到多孔电极基质中，制备了一种新型结构微管固体氧化物燃料电池(MT SOFC)。用相转化法制备的非对称多孔阳极分为两层，厚的燃料传输层具有大的指状孔，而薄的功能层具有小的指状孔。MT-SOFC的最大功率密度分别为0.44、0.54、0.65和0.78W/cm2，温度分别为650、700、750和800°C，燃料为H2-15%H2O，空气为氧化剂。新型结构MT-SOFC将功率输出与快速启动行为相结合，为快速启动高性能功率器件提供了一种潜在的解决方案。
A novel structured micro-tubular solid oxide fuel cell (MT-SOFC) has been fabricated by combining a phase-inversion, dip-coating and high temperature co-sintering process with impregnation of the electrode catalyst into a porous electrode matrix. The asymmetric porous anode made by phase-inversion is divided into two different layers, a thick fuel delivery layer with large finger-like pores and a thin function layer with small finger-like pores. The MT-SOFC demonstrates maximum power densities of 0.44, 0.54, 0.65 and 0.78W/cm2at 650, 700, 750 and 800°C, respectively with H2–15%H2O as fuel and ambient air as oxidant. Combining the power output with the quick start-up behavior, novel structured MT-SOFC offers a potential solution for rapid start-up high performance power devices.
