Abstract
Zinc oxide (ZnO) as a multi-function semiconductor is widely known for photocatalysis and electronic applications but exceptionally new in Solid State Ionics. In this study, a new semiconducting-ionic conductor is reported for solid oxide fuel cells (SOFCs) applications by composing ZnO with an ionic conductor La/Pr co-doped CeO2 (LCP) in various mass ratios. The prepared composites acting as membranes are sandwiched between two Ni0.8Co0.15Al0.05LiO2-? (NCAL) electrodes to construct fuel cells. A remarkable maximum power output of 1055 mW cm?2 is attained along with a high open circuit voltage (OCV) of 1.04 V at 550
