Influence Of Different Ratios Of Gdc-Sdc On Ssc/Gdc–Sdc Dual Composite Cathode For Intermediate-Temperature Solid Oxide Fuel Cells
description Solid oxide fuel cells (SOFCs) have emerged as highly promising contenders in the field of energy conversion, offering enhanced efficiency and environmental sustainability. A considerable amount of effort has been devoted to developing a version of SOFC that operates at intermediate temperatures. Thus, new material development is necessary to enhance cell performance due to limited operating temperatures. The primary objective of this study is to identify the potential of samarium strontium cobaltite (SSC), gadolinium-doped ceria (GDC) and samarium-doped ceria (SDC), i.e. SSC/GDC–SDC dual composite, as a cathode material for intermediate-temperature SOFC (IT-SOFC).
