Development of Novel Anode material for Intermediate Temperature SOFC (IT-SOFC)

Abstract

The present work envisages application of titanium oxycarbide as a possible anode material for intermediate temperature solid oxide fuel cells (IT-SOFC). Titanium oxycarbide samples (TiOxC1-x with x = 0.2 - 0.8) were prepared by reaction-sintering of TiO and TiC powders under vacuum at 1500 C for 5 h. Basic studies on TiOxC1-x (x = 0.2-0.8) with respect to phase purity and stability under oxidizing and reducing environments were carried out. The compatibility of titanium oxycarbide with intermediate-temperature electrolyte material (Ce0.9Gd0.1O3-δ) was studied. The electrochemical properties of planar cells using Ce0.9Gd0.1O3-δ as electrolyte and employing TiO0.2C0.8 and La0.8Sr0.2Co0.2Fe0.8O3-δ based anode and cathode materials were investigated.
