Lanthanum Strontium Vanadate as Potential Anodes for Solid Oxide Fuel Cells

Lanthanum strontium vanadate, (LSV, ), have been synthesized and examined as potential anode materials for solid oxide fuel cells (SOFC). They appear to be chemically compatible with yttria stabilized zirconia (YSZ), at least up to . Electrode performance is evaluated by impedance spectroscopy and dc polarization between 800 and . Good electrode performance is achieved with LSV composite anodes, both in pure and wet (3% , saturated at ). For half-cells with anode, polarization resistance is 0.85 and at in pure and wet , respectively. When drawing a current of at , the overpotential is in pure , and slightly higher in wet , . Further optimization of electrode microstructures is needed to maximize the performance of LSV for potential SOFC application.
