Abstract Slow reaction kinetics of air electrodes is a common problem faced by low‐temperature (<650 °C) oxygen‐ion conducting solid oxide fuel cells (O‐SOFCs) and proton‐conducting reversible proton ceramic (R‐PCCs). Here, an innovative approach proposed to design prepare two efficient durable Ba 0.5 Sr Co 0.8 Fe 0.2 O 3−δ (BSCF)‐based nanocomposites through self‐reconstruction strategy, which aim optimize both the bulk surface properties electrode materials simultaneously. Specifically, with nominal composition 0.4 Cs 0.1 0.7 M (M═Ni, Zr) consisted major perovskite phase surface‐enriched NiO BaZrO 3 minor phases. When Ni (BSCsCFNi) used as in O‐SOFCs, peak power density 1.36 W cm −2 at 650 °C; while Zr (BSCsCFZr) R‐PCCs, 1.24 current −1.98 A (1.3 V) are achieved °C, exhibits stable reversibility over 100 h. Theoretical calculations experiments indicate that + doping enhances conduction oxygen ions protons; nanoparticles enhance adsorption exchange; increase steam hydration capacity. This study provides new idea for designing cells.

Abstract Solid oxide fuel cells (SOFCs) are considered as advanced energy conversion technologies due to the high efficiency, flexibility, and all‐solid structure. Nevertheless, their widespread applications strongly hindered by operational temperatures, limited material selection choices, inferior long‐term stability, relatively costs. Therefore, reducing temperatures of SOFCs intermediate‐temperature (IT, 500–800 °C) range can remarkably promote practical enabling use low‐cost materials enhancing cell stability. conventional cathodes for high‐temperature display electrocatalytic activity oxygen reduction reaction (ORR) at reduced temperatures. Barium cobaltite (BaCoO 3‐δ )‐based perovskite oxides regarded promising IT‐SOFCs because free lattice volume large vacancy content. However, BaCoO ‐based suffer from poor structural thermal compatibility, insufficient ionic conductivity. Herein, an in‐time review about recent advances in is presented emphasizing design strategies including functional/selectively doping, deficiency control, (nano)composite construction enhance ORR activity/durability compatibility. Finally, currently existed challenges future research trends presented. This will provide valuable insights development electrocatalysts various conversion/storage technologies.

Abstract Reversible protonic ceramic cells (r‐PCCs) are highly attractive energy storage and conversion technology, while the insufficient activity of state‐of‐the‐art air electrodes at reduced temperatures strongly limits their practical applications. Herein, this work reports a reduction/re‐oxidation strategy to design new efficient, durable nanocomposite electrode for boosting performance r‐PCCs operated intermediate temperatures. Specifically, single‐phase Ba(Co 0.4 Fe Zr 0.1 Y ) 0.9 Ni O 3‐δ perovskite is selected as precursor, its treatment in hydrogen atmosphere 450 °C then re‐oxidation leads formation nanocomposite, consisted perovskite‐based main phase BaCoO NiO secondary‐phase nanoparticles, where facilitates oxygen surface exchange nanoparticles promote oxygen/steam adsorption. The corresponding r‐PCC exhibits superior 550 symmetrical cell (0.162 Ω cm 2 ), single fuel (0.690 W −2 an electrolysis (−1.066 A 1.3 V). Such thermodynamically stable offers better thermomechanical compatibility with electrolyte because thermal expansion coefficient. As result, durability both modes demonstrated. This study paves way designing outstanding great application potential.
