waterBACKGROUND Anion exchange membrane water electrolysis (AEMWE) is a promising technology for efficiently producing low‐cost hydrogen (H2). Of the two half‐cell reactions in AEMWE, the oxygen evolution reaction (OER) is kinetically sluggish, requiring an electrocatalyst to promote the reaction....
Recent efforts in anion-exchange membrane water electrolysis (AEMWE) focus on developing superior catalysts and membrane electrode assemblies to narrow the performance gaps compared with proton-exchange membrane water electrolysis (PEMWE). Here we present and characterize Ir-free AEMWE cells with NiX ...

Ni2Fe1B OER catalyst scaled up to 5 g was tested as anode electrode in anion exchange membrane electrolysis 1 A /cm2 at 1.67 V and exceptional durability for 60 h in 1 M KOH and 60 °C compared to state of art Ir black catalyst. CRediT authorship contribution statement Alaa Y. Faid:...
Pretreatment for Electrolysis or Fuel Cell Applications: PNB AEMs are provided hydrated and in bromide form. To exchange the bromide for hydroxide ions, soak the membrane in a 1.0 M KOH or NaOH solution for several hours. Rinse with DI water prior to use to remove any surface hydroxide sal...
A heterogeneous nucleation strategy is used to synthesize a NiFe oxygen evolution reaction catalyst for anion exchange membrane water electrolysis. The resulting catalyst has high electrochemical activity and achieves a stable performance for over 21 months owing to a dense interlayer, which anchors the ...
Anion exchange membrane (AEM) electrolysis is a promising solution for large-scale hydrogen production from renewable energy resources. However, the performance of AEM electrolysis is still lower than what can be achieved with conventional technologies. The performance of AEM electrolysis is limited by ...
Water electrolysis produces high purity hydrogen suitable for fuel cell applications [4]. The main types of electrolysis technologies are alkaline water electrolysis and proton exchange membrane (PEM) electrolysis. Of these, alkaline electrolysis is the most commercialized technology [5]. One of the ...
