Controlling Grain Boundary Segregation to Tune the Conductivity of Ceramic Proton Conductors (Adv. Energy Mater. 9/2025)

Year: 2025

Type: article

Abstract: Ceramic Proton Conductors In article number 2404410, Moritz Kindelmann, Olivier Guillon, and co-workers illustrate how controlled acceptor dopant segregation at grain boundaries in a polycrystalline ceramic proton conductor can boost the transport of mobile species (here protons) from one grain to the other, increasing the performance for electrochemical applications like fuel cells and electrolyzers.
