    Abstract:

    The anode material is one of the critical component of a Solid Oxide Fuel Cell (SOFC) which is helpful to provide a triple-phase boundary for hydrogen and oxide ion reactions to take place at high operating temperatures. We, therefore, prepared Ti-substituted SDC20 as anode material and systematically investigated the phase study which showed cubic phase formation of the system and complete solid solubility of the system. Density functional theory (DFT) results showed enhanced oxygen vacancy formation in the prepared sample. The local density of state (LDOS) results showed that bandwidth center energy of Ti doed SDC20 between O-2p and Ti-3d overlapped compared with parent SDC20. Moreover, Ti substitution enhanced the mesoporosity in the sample which helped the electrochemical reaction in the anode side of SOFC. The polarization resistance of Ti-doped SDC20 was compatible with NiO and the composite electrode was stable for long hours. The preliminary results show that Ti-doped SDC20 oxide is a promising cathode material for SOFCs.
