Abstract
In this study, micro-tubular solid oxide fuel cells (MT–SOFCs) were manufactured by successive electrophoretic deposition (EPD) in non-aqueous solvent. At first, stable suspensions of YSZ (Electrolyte), Ni/YSZ (anode) and LSM (cathode) in isopropanol were prepared. The EPD was performed on graphite rods under various voltages and times. The proper EPD condition was determined to prepare porous electrodes and dense electrolyte layers. The graphite rod was decomposed by heating at 900˚C and the resulting tubular thin films were sintered in air at 1350˚C. The microstructure of the sintered samples was studied by SEM analysis. The performance of the SOFC was investigated by electrochemical impedance spectroscopy. It was found that MT–SOFC with an internal diameter of 0.7 mm can be obtained via successive EPD. The maximum power density of the cell was 0.25 W/cm2at 850˚C.
期刊介绍：
While ceramics have traditionally been admired for their mechanical, chemical and thermal stability, their unique electrical, optical and magnetic properties have become of increasing importance in many key technologies including communications, energy conversion and storage, electronics and automation. Electroceramics benefit greatly from their versatility in properties including:
-insulating to metallic and fast ion conductivity
-piezo-, ferro-, and pyro-electricity
-electro- and nonlinear optical properties
-feromagnetism.
When combined with thermal, mechanical, and chemical stability, these properties often render them the materials of choice.
The Journal of Electroceramics is dedicated to providing a forum of discussion cutting across issues in electrical, optical, and magnetic ceramics. Driven by the need for miniaturization, cost, and enhanced functionality, the field of electroceramics is growing rapidly in many new directions. The Journal encourages discussions of resultant trends concerning silicon-electroceramic integration, nanotechnology, ceramic-polymer composites, grain boundary and defect engineering, etc.
