Abstract:Solid oxide fuel cell (SOFC) holds significant application potential for clean and efficient power generation. However, SOFC has not yet achieved large-scale widespread application primarily due to the key materials, which has a significant impact on the overall lifespan of the battery. The preparation technologies of these materials can significantly affect their performance. Therefore, the key material preparation technology of SOFC is of great significance for the development and popularization of fuel cells. This article will provide an overview of key material preparation technologies for fuel cells from a new perspective, focusing on the core process steps of six different preparation technologies and one or more types of substances, which can play an important role in these core steps. Secondly, the difficulty of reaction occurrence and the controllability of reaction process among the six preparation methods are compared and analyzed. Finally, further development and research directions are pointed out for the six preparation techniques listed in this article.
