[Display omitted] •Recent advances of spinel catalysts in DIR-SOFC were explored.•Strategies to enhance spinel catalytic performance discussed.•Specific challenges encountered by spinel catalysts were addressed.•Recent spinel materials as protective coatings for SOFC interconnects identified.•Ni-Cu-Mn spinel as promising platform for methane reforming in DIR-SOFCs. Use of spinel materials in heterogeneous catalysis is highly attractive because of their unique properties, including their high thermal and chemical stability, good electrical conductivity, and tunable catalytic activity. In this review, recent advances in the development of enhanced hydrocarbon reforming catalysts, including spinel materials for direct internal reforming solid oxide fuel cell (DIR-SOFC) applications, are examined comprehensively. This review discusses the structural characteristics of spinel materials, including their crystal structure and redox behavior. To enhance catalytic performance, various strategies, such as doping with metals or non-metals, surface modification, and heterojunction formation, have been employed. The advantages and limitations of these strategies and their effects on the catalytic activity and selectivity of spinel catalysts are analyzed. This review also explores the challenges and future prospects in the development of spinel catalysts, including the optimization of synthesis methods, the development of new catalytic systems, and a deeper understanding of the reaction mechanisms at the atomic and molecular levels. Overall, this review highlights the potential of spinel materials as efficient and versatile catalysts for DIR-SOFC applications, providing a valuable reference for catalysis researchers who aim to develop new and improved spinel catalysts for DIR-SOFC. Additionally, the review discusses the future potential for the novel applications of spinel materials in DIR-SOFC.
