Resumo

Third-generation solid oxide fuel cells or metal-supported solid oxide fuel cells (MS-SOFCs) utilizing metallic substrates for solid oxide fuel cell (SOFC) ceramic thin film deposition offer advantages in terms of weight, robustness, and thermal cycling compared to traditional first-generation (HT-SOFCs: high temperature-solid oxide fuel cells) supported by the electrolyte, and the second-generation (IT-SOFCs: intermediate temperaturesolid oxide fuel cells) supported by the anode or cathode designs. However, interdiffusion between the porous metal substrates (PMSs) and the electrochemically active layers can hinder long-term performance and durability. In this review, we discuss advancements in manufacturing techniques for PMSs, focusing on scalable and cost-effective methods for producing high-quality PMSs, novel materials, and surface engineering techniques to enhance the required properties of PMSs techniques for creating complex and customized PMSs architectures, in addition, the content is covered on substrate degradation, how it can harm MS-SOFCs and strategies to mitigate this damage based on the implementation of a new thin layer made with rare earth elements, namely as a diffusion barrier layer (DBL). This review provides a valuable key insights for researchers and engineers to developing and advancing PMSs for SOFC technology. (AU)
