Abstract:Taking the relevant literature of Science Citation Index Expanded (SCIE) as the analysis data, this paper studies the development trend, national cooperation tendency and Research hotspots of SOFC technology by using literature metrology, co-authorship network analysis and text classification. The results show that the cooperation among countries has obvious tendency and geography, and the focus of R & D has gradually shifted from developed countries such as the United States and Japan to developing countries such as China and India; Research hotspots such as hybrid system design and electrolyte film manufacturing may be the key to promote the industrialization of SOFC technology. Finally, some suggestions are put forward, such as exploring the technical route suitable for China's application scenarios, deepening international cooperation and strengthening the deployment of SOFC innovation chain.
