摘　　要：管式固体氧化物燃料电池(Tubular Solid Oxide Fuel Cell,T-SOFC)是一种全固态、绿色高效、可直接将燃料中的化学能转化为电能的电化学装置,具有启停速度快、密封容易、热循环稳定性好、机械强度高、工作面积大等优点,因而被认为是未来最接近于实用化的一种SOFC构型。相较于氧离子传导型SOFC,质子导体陶瓷燃料电池(Protonic Ceramic Fuel Cell,PCFC)由于质子本身半径较小,迁移所需活化能低,在中低温下表现出优异的电化学性能,而管式结构能改善PCFC强度较低的缺陷,更具实际应用前景。通过对管式PCFC的工作原理、关键材料、制备工艺等方面进行梳理,详细总结了注浆成型、挤出成型、提拉浸渍、相转化、流延成型、等静压成型等工艺制备管式PCFC的进展和面临的难点,最后,对管式PCFC未来的发展和挑战进行了展望。Tubular solid oxide fuel cell(T-SOFC)is an all-solid-state,green and high-efficiency electrochemical device for direct convert of chemical energy in fuel into electrical energy,with the advantages of fast start/stop speed,easy sealing,good thermal cycle stability,high mechanical strength and large active area.It is considered to be the closest to a practical SOFC configuration in the future.As compared with oxygen-ion conductive SOFC,protonic ceramic fuel cell(PCFC)shows excellent electrochemical performance at low and medium temperatures,due to the small radius of protons and low activation energy required for proton migration.Also,the tubular structure solves the problem of low strength of the PCFC,which is more promising for practical applications.The working principle,key materials and preparation process of tubular PCFC are summarized,while the fabrication progress and difficulties,such as slip casting,extrusion,dip coating,phase inversion,tape casting,and isostatic pressure and finally the future development and challenges of tubular PCFC,are discussed and prospected.
