Cu-, Ni- and Fe-doped protective cobalt-manganese spinel coatings for solid oxide fuel cell interconnects

Puntos clave

• Enhanced stability of cobalt-manganese spinel coatings contributes to better performance in solid oxide fuel cell systems.
• Doping with copper, nickel, and iron led to a significant increase in the coatings' protective qualities overall.
• Conducted systematic testing of the doped coatings under various operational conditions to assess their durability and efficacy.
• Results suggest that these doped coatings may enable longer-lasting interconnects, enhancing solid oxide fuel cell lifespan.
