A novel solid oxide fuel cell (SOFC) structure, which is fabricated on a Pd-plated porous stainless steel substrate, was proposed for low-temperature SOFC operation. The surface of the substrate was covered with Pd layer without any pores, which reduces the difficulty of depositing thin film electrolyte on the porous substrate. A 1.2-ȝm thick proton conductive Sr(Zr 0.8 Y 0.2 )O 3-į (SZYO) layer and the cathode of a 100-nm thick (La 0.6 Sr 0.4 )(Co 0.2 Fe 0.8 )O 3-į (LSCF) layer were deposited
