Research status analysis of proton exchange membrane fuel cell based on bibliometric method

Abstract

This research used bibliometric method to analyze the development characteristics of PEMFC during the past 10 years from 2014 to 2023. The results show that the number of articles related to PEMFC in both the CNKI database and the WOS database has a steady growth trend. The top 20 units in terms of the number of articles in the CNKI database were universities and scientific research institutions, and the Wuhan University of Technology came first. In the WOS database, the number of papers published, the number and ranking of highly cited papers, and the in-depth analysis index and ranking of cited references from China were all first. China has the largest cumulative number of papers published (5926 papers in total, accounting for 41.6% of the total number of papers published in this field in the past 10 years), occupying the core position in the international cooperation network, and the quality of papers published by European and American countries was relatively high; keyword cluster analysis has shown that the proton exchange membrane, catalyst, gas diffusion layer, membrane electrode, and cost of PEMFC were the current research focus. Therefore, the development trend of PEMFC key materials was analyzed in detail in this study.
