燃料电池极板材料及制备技术的研究热点与演进

Research Hotspots and Evolution of Fuel Cell Plate Materials and Fabrication Technology

针对Web of Science核心合集数据库中2000年1月至2020年10月的燃料电池双极板材料与制备工艺文献进行计量学分析,并利用CiteSpace可视化分析工具绘制了核心研究国家、作者、研究机构及关键词演进的结构图谱。结果表明:双极板研究热点主要是金属材料双极板的耐腐蚀性与高聚物基复合材料双极板的导电性。金属极板耐蚀性问题存在离子污染、基体材料与涂层技术等研究内容,离子污染研究揭示了极板腐蚀的负面影响,基体材料与涂层技术研究则是去通过调整材料成分或制备工艺上提升性能。高聚物复合材料导电性问题的研究内容是高聚物基体、导电填料以及复合材料导电率等预测模型,导电率预测模型是研究复合材料组成的重要理论依据。

According to the literature on fuel cell bipolar plate materials and preparation processes published in the Web of Science core collection database from January 2000 to October 2020, the literature metrology analysis is carried out, and the core research is drawn by using the Cite Space visual analysis tool. A structural map of the evolution of countries, authors, research institutions, and keywords. The data analysis results show that the research hotspots of bipolar plates are mainly the corrosion resistance of metal bipolar plates and the conductivity of polymer-based composite bipolar plates. The corrosion resistance of metal plates has research contents such as ion pollution, substrate materials and coating technology. Ion pollution studies have revealed the negative effects of plate corrosion. Research on substrate materials and coating technology involves adjusting the material composition or preparation process. The research content of the conductivity of polymer composites is the model for polymer matrix, conductive filler and composite conductivity. The modelfor conductivity is an important theoretical basis for studying the composite composition.
