Bi-doped materials, La, Y and Nb, present at both A and B sites of SrTiO3
have been synthesized and tested as anode material for SOFC. The cell performance of bi-doped anode material e.g., LYST and LNST found to be higher than single-doped anode e.g., LST and NST. 20 wt % Ni-YSZ addition to LYST and LNST increased the cell performance from 23 mW/cm2
to 77 mW/cm2
and 25 mW/cm2
to 38 mW/cm2
, respectively. LYST-Ni-YSZ anode gave the maximum power density 70 mW/cm2
, which is stable for 60 h of operation as shown in fig.1. Physical characterizations e.g., SEM, XRD and TEM of anode materials were investigated to correlate performance of different anodes.
