Abstarct: Fuel cells are electrochemical devices that convert chemical to electrical energy. Two different there is of fuel cells exist including planar and tubular design, among which the tubular design has to better stability against thermal cycles, faster start up time and higher volumetric power and etc. In this research extrusion process was used to prepare micro tubular solid oxide fuel cells. After die design, the proper paste composition for anode material and graphite laxyer was determined by rheological analysis. The viscosity measurements, frequency sweep was were performed. The proper paste composition of the anode paste was 79.5 wt% powder NiOYSZ, 15.5 wt% water, 3 wt% glycerin and 2 wt% methyl cellulose and proper paste composition of the graphite paste was 59 wt% powder graphite, 35.5 wt% water, 2 wt% glycerin and 3.5 wt% methyl cellulose. In order to investigate the effect of graphite poreformer on density, viscosity and extrudability, pastes with 0, 5, 10 and 20 wt% poreformer was prepared. The tension test and DMA analysis was also done. The specimens were sintered at 900 °C, 1000 °C, 1100 ℃, 1250℃ and 1400 °C. The density, thickness, hardness and bending strength was measured. The microstructure of the samples was analyzed by FESEM.
