Preliminary Work for Preparation and Characterization of Anode Supported SOFC Based on Nio-YSZ Material Using Pore-Former

The present work assesses the manufacturing method for producing ceramic-based solid oxide fuel cells (SOFC) using compaction and sintering methods, which are combined by adding pore former to improve the porosity of the produced anode.The ratio of pore former varies between 5%, 10% and 15%.The base cermet material in this work is NiO-YSZ (Nickle Oxide/Yttria Stabilized Zirconia), which is suitable for high-temperature SOFC.The base material is mixed with pore former at the given ratio, followed by ultrasonic cleaning.This work uses polyethylene glycol (PEG, 10%) as binder material.The produced slurry is then dried in electric oven, continued with the compaction process at a pressure of 135MPa and sintered for 4 hours at 1200℃.The addition of pore former leads to significant improvement in the porosity level, with the highest value of 16.67%.It contributes to the excellent performance of the produced anode, particularly for the permeability value.The NiO-YSZ with 15% pore former has the highest permeability value with average of 0.37 m 2 .Moreover, the detailed permeability profile shows the baseline ratio for adding pore former is between 5% and 10%, which experiences significant variation in the porosity level and permeability value.
