Resumo
Solid oxide fuel cells are fabricated by two-step sintering at low
temperature by controlling the morphology of the gadolinium-doped
cerium oxide (GDC) electrolyte powders. The GDC electrolyte was
synthesized by a hydrothermal route to obtain highly reactive
nanorods that can fully densify at temperatures around 1150 °C. The
developed system consists of the GDC electrolyte support,
lanthanum strontium cobalt ferrite (LSCF) cathode and Ni/GDC
anode. The electrolyte support was prepared by uniaxial die pressing
and sintered at 1150 °C, and fuel cells were obtained by co-sintering
electrode layers at the same temperature. The performance of the
cell was evaluated in hydrogen at intermediate temperatures (IT).
The experimental results indicate that high-performance IT-SOFC
can be obtained at low sintering temperatures by controlling the
morphology of electrolyte powder.
