“…In LCFMN, the oxygenion migration barrier is calculated to be 0.095 eV, while the proton migration barrier is 0.84 eV. Although the energy barrier for proton migration is not high compared with some reported triple-conduction cathodes [19], suggesting some proton conduction in LCFMN, the obvious higher energy barrier in proton migration than that for oxygen-ion migration means that oxygen-ion transportation is more favorable in LCFMN than proton transportation.…”

“…Many recent researches in the H-SOFC community have focused on the development of novel highperformance cathode materials for H-SOFCs [16,17]. It should be emphasized that the majority of cathode materials are perovskite oxides or perovskite-related oxides [18,19]. Although various oxides have been tried as cathodes for H-SOFCs [20], their performance is not as good as the recently developed perovskite oxides, implying that more optimizations or material designs are required.…”

A new medium entropy material LiCo 0.25 Fe 0.25 Mn 0.25 Ni 0.25 O 2 (LCFMN) is proposed as a cathode for proton-conducting solid oxide fuel cells (H-SOFCs). Unlike traditional LiXO 2 (X = Co, Fe, Mn, Ni) lithiated oxides, which have issues like phase impurity, poor chemical compatibility, or poor fuel cell performance, the new LCFMN material mitigates these problems, allowing for the successful preparation of pure phase LCFMN with good chemical and thermal compatibility to the electrolyte. Furthermore, the entropy engineering strategy is found to weaken the covalence bond between the metal and oxygen in the LCFMN lattice, favoring the creation of oxygen vacancies and increasing cathode activity. As a result, the H-SOFC with the LCFMN cathode achieves an unprecedented fuel cell output of 1803 mW•cm −2 at 700 ℃, the highest ever reported for H-SOFCs with lithiated oxide cathodes. In addition to high fuel cell performance, the LCFMN cathode permits stable fuel cell operation for more than 450 h without visible degradation, demonstrating that LCFMN is a suitable cathode choice for H-SOFCs that combining high performance and good stability.

With the fast growth of wireless communication technology in high‐frequency ranges, electromagnetic (EM) interference has become a growing concern that has drawn international attention. The development of materials that can absorb EM radiation is a crucial solution. This review provides a detailed overview of ferrites, specifically hexagonal ferrites and their composites for microwave (MW) absorption. It examines hexagonal ferrite classifications based on the stacking order of their fundamental blocks and their synthesis methods and strategies for improving their magnetic properties. On the other hand, this review included a detailed examination of hexagonal ferrites–conducting polymer, hexagonal ferrites–2D materials, and hexagonal ferrite–other nanomaterials composites for MW absorption applications. Enhancing MW absorption in hexagonal ferrites‐based microwave absorption materials (MAMs) regulates their EM characteristics, improves impedance matching, and creates a diversity of loss mechanisms. In addition, the limitations, challenges, and opportunities of hexagonal ferrites‐based MAMs are discussed, which will be helpful to those working in related areas. As a general application potential, it is worth mentioning that, as a result of recent promising findings in the synthesis of hexagonal ferrites‐based composites, hexaferrite‐based composites are suitable devices in the area of microwave absorption.
