基于文献计量的固体氧化物燃料电池技术发展研究

Research on the Development of Solid Oxide Fuel Cell Technology Based on Bibliometrics

旨在揭示固体氧化物燃料电池(SOFC)技术发展历史全貌、深入挖掘全球各国有关合作倾向,并通过数据支撑为预测领域未来发展方向提供参考。利用SCI扩展版数据库的18335条SOFC相关文献记录,运用文献计量法、合著网络分析以及文本聚类法,系统分析SOFC领域的发文趋势和发文国家、地区、机构等分布情况以及研发热点。结果显示:SOFC领域国家间合作有明显倾向性与地缘性,研发重心逐渐从美日等发达国家向中印等发展中国家转移;技术研发以材料科学为核心,混合系统设计、电解质薄膜制造等研究热点可能是推动SOFC技术产业化的关键。最后,提出探索适合中国应用场景的技术路线、深化国际合作以及加强SOFC创新链部署等建议。

The purpose of this paper is to reveal the overall picture of the development history of solid oxide fuel cell(SOFC)technology,deeply explore the trend of cooperation among countries around the world,and provide reference for predicting the future development direction of the field through data support.By using 18335 SOFC related literature records in the SCI expanded database,and using bibliometrics,co-authorship network analysis,and text clustering,it systematically analyzes the trend of the issuance of documents in the field of SOFC,the distribution of countries,regions,institutions,and other research and development hotspots.The results show that in the field of SOFC,the cooperation among countries has obvious tendentiousness,and the R&D focus has gradually shifted from developed countries such as the United States and Japan to developing countries such as China and India;materials science is the core of technology research and development,and research hotspots such as hybrid system design and electrolyte film manufacturing may be the key to promote the industrialization of SOFC technology.Finally,it proposes to explore the technical route suitable for China’s application scenario,deepen international cooperation and strengthen the deployment of SOFC innovation chain.
