Abstract

original image

Getting intimate: A 3D interconnected Bi0.5Sr0.5FeO3−δ (BSF)–Ag electrocatalyst is prepared from a BSF–AgNO3 core–shell precursor in one step. The nanometer-sized Ag enhances the sintering process, enabling an optimum cathode microstructure and good cathode-to-electrolyte attachment upon firing at 850 °C. A solid-oxide fuel cell based on this cathode shows a near 100 % peak power density enhancement at 550 °C.
