Abstract

The oxide composition LaSr2 Fe2 CrO9-δ was tested for application as an anode material for solid oxide fuel cells. Despite the high Fe content, this composition was found to be stable under SOFC anode conditions up to ∼800°C. The composite anode LaSr2 Fe2 CrO9-δ - Gd0.1 Ce0.9 O2-δ was tested in Gd0.1 Ce0.9 O2-δ and La0.9 Sr0.1 Ga0.8 Mg0.2 O3-δ electrolyte-supported cells in air and humidified H2. The maximum power density was ≈365 mW cm2 at 800°C, with a corresponding total cell resistance of ≈0.69 cm2. However, the anode polarization resistance at 800°C was ≈0.25 cm2.
