Air electrode is an essential component of air‐demanding energy storage/conversion devices, such as zinc–air batteries (ZABs) and hydrogen fuel cells (HFCs), which determines the output power and stability of the devices. Despite atom‐level modulation in catalyst design being recently achieved, the following air electrodes have received much less attention, causing a stagnation in the development of air‐demanding equipment. This Progress Report begins with the evolution of air electrodes for ZABs and HFCs from the early stages to current requirements. Then, the operation mechanism and the corresponding electrocatalytic mechanisms of ZABs are summarized. In particular, by clarifying the air electrode interfaces of ZABs at different scales, several approaches to improve the air electrode in rechargeable ZABs are reviewed, including the innovative electrode structures and bifunctional oxygen catalysts. Afterwards, we explain the operating mechanisms of proton exchange membrane fuel cells (PEMFCs) and anion‐exchange membrane fuel cells (AEMFCs). Subsequently, the strategies employed to enhance the efficiency of the membrane electrode assembly (MEA) in PEMFCs and AEMFCs, respectively, are highlighted and discussed in detail. Last, the prospects for air electrodes in ZABs and HFCs are considered by discussing the main challenges. This Progress Report aims to facilitate the industrialization of ZABs and HFCs.This article is protected by copyright. All rights reserved

In recent years, the rapid growth in renewable energy applications has created a significant demand for efficient energy storage solutions on a large scale. Among the various options, rechargeable zinc‐air batteries (ZABs) have emerged as an appealing choice in green energy storage technology due to their higher energy density, sustainability, and cost‐effectiveness. Regarding this fact, a spotlight is shaded on air electrode for constructing high‐performance ZABs. Cobalt oxide‐based electrocatalysts on the air electrode have gained significant attention due to their extraordinary features. Particularly, exploration and integration of bifunctional behavior for energy storage has remarkably promoted both ORR and OER to facilitate the overall performance of the battery. The plot of this review is forwarded towards in‐depth analysis of the latest advancements in electrocatalysts that are based on cobalt oxide and possess bifunctional properties along with an introduction of the fundamental aspects of ZABs, Additionally, the topic entails an examination of the morphological variations and mechanistic details mentioning about the synthesis processes. Finally, a direction is provided for future research endeavors through addressing the challenges and prospects in the advancement of next‐generation bifunctional electrocatalysts to empower high‐performing ZABs with bifunctional cobalt oxide.
