Solid Oxide Fuel Cells and Electrolysis for Power and Hydrogen Production
This community develops ceramic electrochemical devices that convert chemical energy into electricity or split water and carbon dioxide into fuels, primarily for stationary power generation and green hydrogen production.
The work centers on solid oxide electrolytes, specifically yttria-stabilized zirconia and doped ceria, and the development of perovskite-based cathodes and anodes. A major strand of research focuses on lowering operating temperatures to intermediate levels to improve durability and reduce costs, while another explores reversible operation where the same cell acts as both a fuel cell and an electrolyzer. Recent efforts emphasize high-entropy materials, proton-conducting ceramics, and advanced sintering techniques to enhance ionic conductivity and mechanical stability.
The largest share of the community's output is found in cerium research, accounting for 7.0% of all tracked cerium papers, followed by lanthanum at 6.9% and yttrium at 4.6%. The community also represents a significant portion of zirconium research, with a 3.9% share.
The community comprises 28,504 papers, with the most frequent venues being Solid State Ionics, International Journal of Hydrogen Energy, and Journal of Power Sources.
Current research is actively pursuing high-entropy perovskite cathodes, machine-learning-informed electrode design, and strategies to suppress degradation mechanisms in long-term stack operation.
