Alloying Cu, Fe, and Co in Ni/YSZ Electrodes for High‐Temperature CO2 Electrolysis: Impact on TPB Density, Activity, and Carbon Deposition Resistance

Carbon Energy, EarlyView.
Systematic alloying of Ni with Cu, Fe, and Co in Ni/YSZ electrodes modifies active site density up to 43%, decreases activation energies by up to 44%, and reduces carbon deposition fourfold. Cu–Ni alloy is among the most promising alloy catalysts for electrochemical CO2 reduction in SOECs.

Direct Capture of Dynamic Surface Reconstruction in a Perovskite Cathode via Operando Raman Spectroscopy

Carbon Energy, EarlyView.
Operando Raman spectroscopy directly captures the dynamic form conditions of the BaCoO3‐δ phase on the BSCY surface. This observation provides critical insight into the phase evolution mechanisms, which are essential for optimizing the performance and stability of BSCY‐based protonic ceramic fuel cell cathodes.

Sonochemistry in the service of SOFC research

Ultrasonics Sonochemistry, 2014
Decoration of SOFC anode cermets with metal nanoparticles (NPs) enchance their ability and stability in natural gas to hydrogen reform. A novel sonoelectrochemical approach of Au-NPs synthesis (mean 12.31±2.69nm) is suggested, according to which the sonication is held constant while the electrochemical activity is either pulsed or continuous.

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.
