AB A novel electrode architecture consisting in alternating layers of La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) andCe0.9Gd0.1O1.95 (CGO) is prepared for the first time by spray-pyrolysis deposition and investigated as cathodematerial for Solid Oxide Fuel Cells (SOFCs). Cathodes with different number of LSCF/CGO bilayers (N=0, 3 and5) are prepared and characterized. The multilaminated cathodes are highly porous with connected verticalchannels and display an unusual undulated morphology, which increases the contact area between CGO andLSCF materials. The oxygen reduction activity has been investigated by impedance spectroscopy, obtainingimproved values of polarization resistance as the number of bilayers increases due to extended three-phaseboundary(TPB) length for the oxygen reduction reactions.
