Bibliometric Analysis of Publications Related to Solid Oxide Fuel Cell (SOFC)

The growing interest in renewable energies amid global energy challenges highlights the promising technology of solid oxide fuel cells (SOFCs) due to their efficiency, low pollutant emissions, and flexibility in using renewable sources. This study conducts a bibliometric analysis, identifying over 18,000 documents distributed across 1,800 journals worldwide. Between 2014 and 2024, there has been a significant increase in academic output on the topic, recently surpassing 141 publications annually. However, Brazil still shows a relatively modest presence in this research area. The study underscores the increasing potential of SOFCs and points to research and development opportunities that remain to be explored.
