In recent years, alkaline exchange membrane water electrolysis (AEM-WE) has attracted a lot of attention for its potential cost reduction compared to traditional systems. Despite this promise, challenges related efficiency and stability must be effectively addressed fully realise the AEM-WE. This paper presents comprehensive investigation an AEM-WE single-cell including electrochemical impedance spectroscopy (EIS) in conjunction with equivalent circuit model (ECM). For first time...
Hydrogen produced by electrolysis using renewable energy sources offers a zero-emission alternative to fossil-based providing high efficiencies in all sectors. Anion Exchange Membrane Water Electrolysis (AEM-WE) combines the advantages of established technologies, alkaline (AEL) and proton exchange membrane (PEM) water electrolysis. However, AEM-WE still requires optimization, especially with regard membrane, catalysts electrode structure. In this contribution we focus on improvement...
Anion exchange membrane water electrolysis (AEM-WE) is a promising method for hydrogen production, offering advantages over proton (PEM-WE), such as the use of nonprecious metal catalysts and perfluorosulfonic acid free membranes. Despite achieving impressive current densities, challenges in efficiency stability remain. This study employs electrochemical impedance spectroscopy (EIS), equivalent circuit model (ECM) distribution relaxation times (DRT) analysis to investigate AEM-WE cells. DRT...

Anion exchange membrane water electrolysis (AEM-WE) stands out as a promising method for hydrogen production from renewable energy sources. Unlike proton (PEM-WE), AEM-WE offers the advantage of nonprecious metal catalysts due to mild alkaline conditions, while still enabling compact cell design and operation under differential pressure. Remarkable performances AEM-electrolysis cells have been demonstrated in literature, achieving current densities up 7.68 A·cm −2 [1], surpassing record...
