Abstract

Ordered macroporous Sr0.5Sm0.5CoO3 structrures with an average pore size of 140 nm have been prepared using closepacked arrangement of monodispersed polystyrene spheres as templates. A fuel cell using ordered macroporous Sr0.5Sm0.5CoO3 as the cathode, gadolinia-doped ceria (GDC) film as the electrolyte, and GDC–NiO as the anode generated maximum power densities of 150, 196 and 267 mW/cm2 at 500, 550 and 600 °C, respectively.
