Entropy-driven order-to-disorder transition in perovskite anodes for high-performance solid oxide fuel cells (opens in new tab)

Solid oxide fuel cells (SOFCs) enable direct and efficient conversion of transportable hydrocarbons into electricity, offering a scalable pathway for carbon-neutral energy systems. A critical challenge in SOFC development lies in the atomic-scale structural regulation of perovskite-type anodes, which is essential for enhancing hydrocarbon oxidation kinetics while mitigating carbon deposition issues. To overcome this fundamental limitation, we propose an entropy-driven strategy to induce order...
