Electrochemical characteristics of La 0.6 Sr 0.4 Co 1−y Fe y O 3 (y=0.2–1.0) fiber cathodes

Electrochemical Impedance Spectroscopy of Electrospun La0.6Sr0.4Co0.2Fe0.8O3–δ Nanorod Cathodes for Intermediate Temperature – Solid Oxide Fuel Cells

“…Additional benefits are the unique properties of electrospun structures, in particular high surface area and porosity, and efficient electron/ion transport along the fiber longitudinal direction , . Electrospun La 1– x Sr x Co 1– y Fe y O 3– δ cathodes infiltrated with gadolinia doped ceria (Ce 1– x Gd x O 2– δ ) have been investigated as cathodes for IT‐SOFCs both experimentally and theoretically , demonstrating improved performance over conventional infiltrated nanoparticle‐structured electrodes based on the same materials, especially in terms of long‐term stability . However, the pristine 3‐dimensional structure and the resulting electrochemical behavior of the electrospun cathodes have received little attention so far , , .…”
