Abstract
Presently, scientists are vigorously exploring effective, sustainable and environmentally friendly energy sources, which has lent momentum to the adoption of solid oxide fuel cells (SOFCs).The present research focuses on the synthesis and investigation of a binary oxide composed of lanthanum and copper, which was characterized using FTIR, XRD, SEM, XPS and BET.The findings revealed that the surface morphology exhibited mesoporosity, due to the interconnection and sintering of the pliable, rod-like crystalline structure, which was determined to be the binary oxide La2CuO4.Furthermore, within the temperature range of 500 to 600°C, a two-fold increase in current density through the anode material was observed for every 50°C temperature increment, coupled with a nearly three-fold reduction in polarized resistance.
