Utilizing a screening strategy featuring energy efficient and rapid solution combustion (SC) synthesis technique, and the high throughput NuVant system, a library of conductive perovskites was synthesized and tested as anode electrode in the direct ethanol fuel cell (DEFC) conditions. It was found that a variety of Ru-based perovskites showed considerable electro-catalytic activity for ethanol oxidation. Further, it was demonstrated that the perovskite-platinum catalysts with low noble metal loading prepared directly in by SC method exhibit comparable performance with standard Pt-Ru alloy.
