Electrochemical CO2 reduction reaction (ECCO2RR) is gaining significant attention as a promising solution to climate change and the energy crisis. Among the various approaches, membrane electrode assembly (MEA) reactors have emerged as a key focus in ECCO2RR research due to their high current density and excellent product selectivity. MEA reactors achieve efficient electrochemical conversion by separating the anode and cathode and employing ion exchange membranes to facilitate the transport of protons or other ions. Despite their potential, MEA reactors face several challenges, including the durability of membrane materials, optimization of product selectivity, and precise control of reaction conditions. This article reviews the latest advancements in membrane electrode reactors for electrochemical carbon dioxide reduction, analyzes the main challenges, and proposes potential directions for future research and applications.
