Direct Catalyst Coating In article 2200332, Severin Vierrath and co-workers demonstrate the fabrication process of anion-exchange membrane water electrolyzer cells in a simplified way. The catalyst layers (black) are directly deposited onto anion exchange (yellow) via bar-coating. molecules split into hydrogen (white) oxygen (red). Cover illustration by Luca Bohn.

Anion exchange membrane (AEM) is one of the most important components in anion water electrolyzer (AEMWE) and fuel cell (AEMFC). Herein, challenges corresponding strategies AEM development are summarized to provide valuable predictions for advancement hydrogen-electricity energy conversion devices.

Anion-exchange membrane water electrolyzers (AEMWEs) are prepared as catalyst-coated membranes using varying amounts of ionomer in the catalyst layers.

In present research work, homogeneous anion exchange membranes based on polysulfone (QAPSFs) were prepared via chloromethylation, amination and alkalization. In amination step, trimethylamine and N,N,N',N'-tetramethyl-1,6-hexanediamine were used as amination and crosslinking agents, respectively. The chloromethylated polysulfone was characterized by 1HNMR spectroscopy and chloromethylation degr...

Anion-adsorbing membranes provide an interesting possibility to remove toxic arsenate and chromate from drinking water. A promising way prepare anion-exchange materials is introduce positively charged amine groups on polymers. In this study, polyacrylonitrile (PAN) ultrafiltration were modified with functionalities the membranes. The success of modifications was demonstrated using infrared spec...

The green-H2 production through water electrolysis from renewable energies is vital in the context of developing a sustainable and cost-effective methodology. Anion exchange membrane electrolyzer (AEMWE) considered as promising energy conversion device, which can be an alternative to fossil fuel-based energyplatforms. AEMWE employ inexpensive nonprecious metal catalysts current collectors, pref...

In the current research, polyvinylchloride based mixed matrix heterogeneous anion exchange membranes were prepared by a solution casting technique. Titanium dioxide nanoparticles were also utilized as inorganic filler additive in the membrane fabrication. The effect of TiO2 nanoparticles concentration in the casting solution on the membrane physico-chemical properties was studied. Membrane wate...
