A novel electrode architecture consisting in alternating layers of La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) and
Ce0.9Gd0.1O1.95 (CGO) is prepared for the first time by spray-pyrolysis deposition and investigated as cathode
material for Solid Oxide Fuel Cells (SOFCs). Cathodes with different number of LSCF/CGO bilayers (N=0, 3 and
5) are prepared and characterized. The multilaminated cathodes are highly porous with connected vertical
channels and display an unusual undulated morphology, which increases the contact area between CGO and
LSCF materials. The oxygen reduction activity has been investigated by impedance spectroscopy, obtaining
improved values of polarization resistance as the number of bilayers increases due to extended three-phaseboundary
(TPB) length for the oxygen reduction reactions.
