NiO Dissolution in Molten Carbonate Fuel Cell Cathodes: Challenges and Strategies for Long‐Term Stability

ChemElectroChem, Volume 13, Issue 13, 2 July 2026.
Molten carbonate fuel cells (MCFCs) enable efficient power generation and CO2 capture but suffer from nickel oxide (NiO) cathode dissolution, which limits lifetime. This review summarizes strategies to mitigate NiO degradation, including coatings, doping, alternative cathode materials, and electrolyte modification.
