Solid oxide fuel cells (SOFCs) hold promise for energy conversion technology, but face challenges such as component degradation and sulfur poisoning. This article discusses various electrode materials and improvements to enhance electrochemical performance, highlighting critical challenges for advancement.
Solid oxide fuel cells (SOFCs) have the potential to be used in energy conversion technology. Most of the studies aimed at modifications of anode concerning various issues such as component degradation, sulfur poisoning, and carbon deposition at high temperatures, hindering its applications at the industrial level. Different perovskite structure-related compounds are discussed in this article, which could be possible electrode materials in SOFCs. Literature also revealed the successful utilization of various cathode materials in a wide range of temperature in which cobalt-based materials exhibits higher conductivity than cobalt-free once. The selection of initial composition, dopants addition in different electrodes with critical challenges inherent to this material family have been assessed herein which play a vital role in enhanced electrochemical performance. The other aim of this review article is to provide some useful recommendations and prospective directions for designing future electrode materials of SOFCs. The review analysis is done based on different processing parameters and their effect on thermal expansion coefficient, electrical conductivity, mechanical and electrochemical properties, etc. In a nutshell, a detailed overview is critically analyzed for energy conversion and storage applications, which can open many gateways towards the advancement of SOFCs.
