Abstract

A novel protonic ceramic composite is synthesized that comprises nanoscale nickel metal films partially decorating the grain boundaries of the proton-conducting ceramic, BaCe0.7Zr0.1Y0.1Yb0.1O3−δ (BCZYYb). Low-temperature proton conductivity improvements of up to 46× vs. a control are observed, suggesting a novel method to enhance ion conductivity in polycrystalline materials.
