Abstract
This research intends to conduct scientometrics and knowledge management for fuel cell system research for efficiency energy based on data on Scopus from 2011 to 2024. Using statistical methods and analytical software VOSviewer, 1,399 articles published in 247 data sources were analyzed, and the results showed that the average growth rate per year was 12.79% and the average number of citations per article was 36.79. China is considered to be the leader in 2,678 articles and 14,189 citations, with Iran and the US (356 and 503 articles) are mainly involved in the technological improvements in Proton Exchange Membrane Fuel Cells (PEMFC) and Solid Oxide Fuel Cells (SOFC), as highlighted in the findings. Leading the field by far are Energy and Applied Energy with 225 and 177 papers, having both h and g above 60 and 80, respectively. The existence of high-frequency keywords such as “energy efficiency” (1,456 occurrences), “SOFC” (614 occurrences), and “PEMFC” (612 occurrences) confirms the importance of performance improvement in research field, while some keywords including “carbon dioxide” and “waste heat” show us that more attention are attached to environmental issue. This is interesting because international collaborations, which forms 26.45%, is significant, and perhaps there is a need for improved linkages. Knowledge management, driven by data and interactive dashboards, filled those gaps, including one for green hydrogen infrastructure. According to the study, fostering international collaboration support to a new generation of researchers, fostering sustainable materials and focusing on hybrid systems could pave the road towards fuel cells commercialization.
