Exploring the potential of triple conducting perovskite cathodes for high-performance solid oxide fuel cells: a comprehensive review

Abstract

Solid oxide fuel cells (SOFCs) represent a class of energy conversion devices that exhibit exceptional efficiency in the direct conversion of chemical energy from diverse fuel sources into electricity. The...

Balancing the triple conductivity of zinc-doped cathodes for proton-conducting solid oxide fuel cells

“…However, it's worth noting that these cobalt-based cathodes are plagued by issues such as cobalt evaporation and high thermal expansion coefficients, which pose challenges to the long-term stable operation of H-SOFCs. 8–10 Subsequently, cobalt-free cathodes for H-SOFCs have emerged, offering both excellent chemical stability and appropriate ORR activity, presenting a promising solution to address the challenges posed by cobalt-based cathodes. 11–14…”
