Solid Oxide Fuel Cells and Electrolysis for Energy Conversion
This community develops ceramic materials and electrochemical systems that convert chemical energy into electricity or use electricity to split water and carbon dioxide into fuels.
The work centers on solid oxide electrolytes, primarily yttria-stabilized zirconia and barium zirconate, and the perovskite oxide cathodes and anodes that interface with them. Researchers focus on lowering operating temperatures, enhancing oxygen reduction and evolution reaction kinetics, and improving the durability of these ceramic components. A significant strand of research addresses reversible operation, where the same device functions as both a fuel cell and an electrolyzer. Materials strategies include doping ceria, developing high-entropy perovskites, and optimizing thermal expansion matching to prevent mechanical failure during thermal cycling.
The largest share of this community’s output is found in yttrium research, representing 6.6% of all yttrium literature, with 1,820 papers in this group. Lanthanum research follows, accounting for 8.4% of that element’s literature with 1,539 papers, and zirconium research contributes 3.1% of its literature with 1,211 papers.
The community comprises 12,579 papers, publishing most frequently in the International Journal of Hydrogen Energy, Journal of Power Sources, and Solid State Ionics.
Recent work continues to focus on high-entropy perovskite cathodes, machine-learning-guided material design, and mechanisms for suppressing degradation in long-term stack operation.
