(La,Sr)(Ti,Ni)O3 and YSZ Composite Anodes with Impregnated GDC Nanoparticles as Fuel Electrodes for Solid Oxide Fuel Cells

Titanate anode materials have emerged as a focal point of research in solid oxide fuel cells (SOFCs) due to their high adaptability to diverse fuel gases.To further enhance their performance, we propose an impregnation strategy to create a composite electrode by applying a gadolinium-doped cerium oxide (GDC, Ce0.9Gd0.1O2-σ)solution to a La, Ni co-doped SrTiO3 (LSTN) anode.This approach aims to improve the effectiveness of the anode material in SOFC applications.The composite anode, which was treated with of GDC 3 impregnation cycles, achieved a polarization resistance of 1.21 Ω cm² and a maximum power density of 79.52 mW cm⁻² after being reduced at 800 °C for 2 hours.It was tested at various temperatures and with different amounts of impregnated GDC.
