Abstract:

Tubular solid oxide fuel cells (SOFCs) have the advantages of fast start-stop speed, good thermal cycle stability, high conversion efficiency, a wide range of fuel applicability, and no emissions pollution. Therefore, they are an ideal power generation device. In this review, a visual analysis of the relevant literature on tubular SOFCs published in the past 5 years was conducted. First, the research hotspots, significant points of technology development, and the main countries researching tubular SOFCs were analyzed. Then, we investigated and tracked cutting-edge research works in tubular SOFCs. The following areas were covered: cell structure, preparation methods, and critical materials. These variables significantly impact the efficiency, output performance, operational stability, and cost of tubular SOFCs. In the section on cell structure, the characteristics of different support structures are discussed, and then some new research results on improving and optimizing cell configuration are introduced. In the fabrication section, the applications of the phase-inversion method, freeze-casting method, and three-dimensional laser printing are introduced. Finally, in the section on key materials, the microstructure regulation and the development of new materials are introduced. In all, representative and innovative research works on tubular SOFCs are introduced in this study. Additionally, the advanced strategies and solutions to solving the problems of tubular SOFCs are explored. This review provides guidelines for the high-quality development and commercialization of tubular SOFC technology.
