“…The manifestation of conductivity isotope effect is regarded as verification of the H + contribution. , Simultaneously, the Grotthuss mechanism of proton conduction was further confirmed by the corresponding proportions of σ total in H 2 O- and D 2 O-wetted air . The best-ever reported electrical conductivity (8.2 × 10 –3 S cm –1 ) for HEPO ,,, is achieved using this BSZCYYbD measured in H 2 O-humidified air at 600 °C, which is comparable to those of the classical proton-conducting ceramics − (see Table S3 in the Supporting Information).…”

High-entropy materials are attracting ever-increasing concern for their unique structural features and unprecedented potential applications. In this study, we design and successfully prepared single-phase high-entropy perovskite oxide (HEPO) BaSn0.16Zr0.24Ce0.35Y0.1Yb0.1Dy0.05O3−δ (BSZCYYbD) to use as a new class of proton conductor, which is first applied to protonic ceramic fuel cells (PCFCs) below 600 °C. The BSZCYYbD exhibits excellent chemical and structural stability, high densification, and mechanical properties. The protonic conduction in BSZCYYbD is proved by the proton-conductor isotope effect and hydration effect. The protonic conductivity of BSZCYYbD is the highest ever reached in the high-entropy proton conductors, which is 8.3 mS cm–1 in humidified air (3% H2O) at 600 °C. An anode-based PCFC with BSZCYYbD electrolyte (∼45 μm) demonstrates a favorable output of 318 mW cm–2 at 600 °C. Our study offers a strategy for the design of superior proton-conducting electrolytes based on HEPOs, which hold promise for diverse electrochemical applications.

A novel strategy was proposed to enhance the sinterability and electrical properties of BaZr 0.1 Ce 0.7 Y 0.2 O 3-δ (BZCY) proton-conducting electrolyte by adding 10 wt.% La 0.9 Sr 0.1 Ga 0.8 Mg 0.2 O 3-δ (LSGM) to form a 90 wt.% BZCY-10 wt.% LSGM (BL91) composite electrolyte. XRD patterns showed that no reaction occurred between How to cite this article: Yu S, Wang Z, Yang L, et al.
