Abstract
Abstract Reversible proton ceramic cells (R‐PCCs) offer a transformative solution for dual functionality in power generation and energy storage. However, their potential is currently obstacles by the lack of high‐performance air electrodes combining high electrocatalytic activity with durability. Here, an innovative air electrode composed of high‐entropy driven self‐assembled xNiO‐Pr 0.2 La 0.2 Ba 0.2 Sr 0.2 Ca 0.2 Fe 0.8 Ni 0.2−x O 3−δ (N‐XFN) composites is presented, which result from the unique lattice distortion effects inherent in high‐entropy perovskites. The experimental results coupled with density functional theory (DFT) calculations verify that the lattice distortion at the high‐entropy A‐site…
