Optimization analysis of solid oxide fuel cells with ceria-based single cells using computational fluid dynamics

The SOFC simulations in this research are conducted at temperatures of 600°C, 700°C, and 800°C, focusing on the Ni-SDC anode, SDC electrolyte, and LSCF-SDC materials used in the SOFC single cell. Initially, the single-cell model is created using CAD software, followed by the development of a comp...
