dc.description.abstractAnode support microtubes are fabricated by tape casting and isostatic pressing as an alternative method to conventional extrusion for microtubular solid oxide fuel cells (SOFCs). Continuous NiO (nickel oxide)-YSZ (yttria stabilized zirconia) strip manufactured by tape casting is rolled around a metal pin followed by isostatic pressing, which makes the isostatic pressing step significant. Therefore, isostatic pressing process parameters yielding high performance microtubular anode supports in the structural, mechanical and electrochemical points of view are experimentally determined. For this purpose, different support microtubes are fabricated by varying the pressure, temperature and duration for the isostatic pressing. The microstructural and mechanical properties of the microtubes are determined by a scanning electron microscope and three point bending test, respectively, whereas different microtubular cells are manufactured based on these supports to measure their electrochemical performance. The results show that the optimum pressure, temperature and duration for the isostatic pressing should be at least 70 MPa, 60 C and 4 min, respectively, to obtain robust supports without any structural defects. The cells based on these supports also exhibit similar performances at all temperatures studied. Therefore, the suggested method is considered appropriate to fabricate support tubes/microtubes for SOFCs regarding the mechanical and electrochemical performance.
