基于CiteSpace的国内外氢燃料电池研究知识图谱分析

Knowledge Graph Analysis of Domestic and Foreign Hydrogen Fuel Cell Research Based on Cite Space

为了解国内外氢燃料电池领域的研究现状、演进趋势和热点问题,从1995—2021年中国知网和Web of Science中分别筛选398篇和2122篇中、英文献作为统计样本,运用文献计量学和CiteSpace软件对国内外氢燃料电池研究论文的发表趋势、期刊来源、研究机构、高被引文献、关键词共现与突现进行分析。研究结果表明:英文文献总发文量高于中文文献总发文量,但发文期刊较为分散;发文量较高的机构大部分来自韩国;最高被引文献来自德国;中文文献研究主要聚焦于氢燃料电池、制氢、氢能和催化剂,而英文文献研究主要关注performance、system、catalyst、nanoparticle、temperature、composite;电动汽车、氢储能、加氢站是国内的研究热点和趋势。

In order to understand the research status, evolution trend and hot issues in the field of hydrogen fuel cells at home and abroad, 398 and 2122 Chinese and English documents were selected from CNKI and Web of Science from 1995 to 2021 as statistical samples, using bibliometrics and CiteSpace software to analyze the publication trends, journal sources, research institutions, highly cited literature, keyword co-occurrence and emergence of domestic and foreign hydrogen fuel cell research papers. The research results show that: the total publication volume of English literature is higher than that of Chinese literature, but the published journals are scattered;most of the institutions with high publication volume are from South Korea;the most cited literature is from Germany;Chinese literature research mainly focuses on hydrogen fuel cells, hydrogen production, hydrogen energy and catalysts, while the English literature research mainly focuses on performance, system, catalyst, nanoparticle, temperature, composite;electric vehicles, hydrogen energy storage, and hydrogen refueling stations are the research hotspots and trends in China.
