Nano Research & Applications

Abstract

Nanomaterials were prepared using solution combustion method. These materials were further used as different parts of solid oxide fuel cell. In this report I have included synthesis and characterization of anode, cathode and electrolyte materials and also fuel cell testing report (open circuit voltage). Anode materials: NiO-GDC, CuO-NiO-GDC, NiO-Al2O3, and AFL/NiOGDC, cathode material: La0.6Sr0.4Co0.2Fe0.8O3 (LSCF), and electrolyte material: Gd0.1Ce0.9O1.95 (GDC). The conductivity of anode functional layer (NiO-Al2O3) in biogas is 160 x 10-3 S/cm and of CuO-NiOGDC in biogas is 35 x 10-3 S/cm. The SOFC formed with CuO-NiOGDC anode exhibits OCV of 0.92 V at 500 oC and the OCV of the cell with NiO-GDC as anode is 0.7 V at 500 oC. The single cell (CuONiO-GDC/GDC/LSCF) can achieve highest power density 11.38 mW/cm2 and highest current density 31.68 mA/cm2 at 800 oC.
