Global Trends in PEM Electrolyzer Research Based on Published Articles

Abstract

As one of the representative new energy, hydrogen has received widely attention in recent years. PEM electrolyzer plays a central role in hydrogen production process. In this paper, 411 publications related to PEM electrolyzer collected from Web of Science released between 2005 and 2022 were analyzed through bibliometric to explore research hot-spots and future trends by analyzing publication and citation, countries and authors, journals and keywords. According to statistics and analysis, (1) Iran and Dincer Ibrahim were the most productive countries and authors, respectively. (2) International Journal of Hydrogen Energy was the mainly journal of PEM electrolyzer related publications. (3) Component and Hybrid System are likely to remain prominent areas of research in the foreseeable future. (4) Current hot-spots, such as Two Phase Flow and Hybrid System, may receive even more attention in the foreseeable future.
