Among the three types of Solid Oxide Fuel Cell (SOFC), intermediate temperature solid oxide fuel cells (IT-SOFC) have been widely developed due to reducing operating costs and materials. In this study, we produced an anode-supported IT-SOFC cell through the dry-pressing method for NiO-CSZ anode production and spray coating technique for Calcia-Stabilized Zirconia (CSZ) electrolyte and calcium cobalt zinc oxide (CCZO)-CSZ cathode fabrication. A single cell was enhanced by changing the anode's composition, increasing the sintering temperature, using a ball mill as mixing equipment, and multiplying the coating of the electrolyte. The cell with eight times of electrolyte coating had a greater peak power density than that of one time of electrolyte coating even though the curvature of eight times of electrolyte coating was higher. Additionally, the cell performance with eight times of electrolyte achieved the peak power density of 0.24; 0.35; and 1.08 mW/cm2 and the ohmic resistance of 168.3; 90.10; and 26.78 Ω at the operating temperature of 600, 700, and 800 °C, respectively. © (2024), (Faculty of Engineering, Universitas Indonesia).
