Abstract

A lanthanum and calcium co-doped A-site deficient strontium titanate (LSCTA-) was used as alternative anode material in Solid Oxide Fuel Cells (SOFC) with an active area of 100 cm2. Cell performance was tested in both short (5 cell) stack configuration, as well as a full HEXIS Galileo system (nominally 1 kW AC). Impregnation with various electrocatalysts, such as nickel and ceria, yielded promising fuel cell performance at this scale. The system test initially produced 70% of the nominal output power and is to the authors' knowledge the first all-oxide SOFC test on this scale. The strontium titanate backbone provides sufficient electronic conductivity to ensure acceptable ohmic losses. Power..
