Cation Exchange Membranes and Process Optimizations in Electrodialysis for Selective Metal Separation: A Review
Tekinalp, Önder; Zimmermann, Pauline; Holdcroft, Steven; Burheim, Odne Stokke; Deng, Liyuan (Peer reviewed; Journal article, 2023)The selective separation of metal species from various sources is highly desirable in applications such as hydrometallurgy, water treatment, and energy production but also challenging. Monovalent cation exchange membranes ... -
Does power ultrasound affect hydrocarbon Ionomers?
Adamski, Michael; Peressin, Nicolas; Balogun, Emmanuel; Pollet, Bruno; Holdcroft, Steven (Peer reviewed; Journal article, 2021)The effect of low-frequency high-power ultrasound on hydrocarbon-based ionomers, cation exchange sulfonated phenylated polyphenylene (sPPB-H+) and anion exchange hexamethyl-p-terphenyl poly(benzimidazolium) (HMT-PMBI), was ... -
Does power ultrasound affect Nafion® dispersions?
Adamski, Michael; Peressin, Nicolas; Holdcroft, Steven; Pollet, Bruno (Journal article; Peer reviewed, 2020)The effect of low frequency power ultrasound on Nafion® ionomer used for fabricating proton exchange membrane fuel cell (PEMFC) and water electrolyzer (PEMWE) catalyst inks was investigated. In this study, a series of ... -
Measuring the thermal conductivity of membrane and porous transport layer in proton and anion exchange membrane water electrolyzers for temperature distribution modeling
Bock, Robert; Karoliussen, Håvard; Seland, Frode; Pollet, Bruno; Thomassen, Magnus; Holdcroft, Steven; Burheim, Odne Stokke (Journal article; Peer reviewed, 2019)Water electrolyzers that use a membrane electrolyte between the electrodes are a promising technology towards mass production of renewable hydrogen. High power setups produce a lot of heat which has to be transported through ...
