Cost-effective electrodes for alkaline water electrolysis
Zamanizadeh, Hamid Reza (Doctoral theses at NTNU;2022:16, Doctoral thesis, 2022)Green hydrogen production using water electrolysis has potential to be the key component in storing and coupling renewable energy to the transportation and chemical sectors. Alkaline water electrolysis offers a relatively ... -
Investigating Transient Operation Effects: Anode Catalyst Degradation Due to Hydrogen Crossover in a PEM Water Electrolyser
Kvalvik, Eivind (Master thesis, 2024)Hydrogen fortsetter å utforskes aktivt som en potensiell erstatning for fossilt brensel i jakten på et nettonullutslippsamfunn. Proton exchange membrane water electrolysis (PEM-WE) skiller seg ut som en attraktiv metode ... -
Performance of activated stainless steel and nickel-based anodes in alkaline water electrolyser
Zamanizadeh, Hamid Reza; Oyarce Barnett, Alejandro Ricardo; Sunde, Svein; Pollet, Bruno; Seland, Frode (Peer reviewed; Journal article, 2023)Four different alloys including SS316, SS304, Inconel718 and Incoloy800 are activated by electro-oxidation at +1.70 V vs. RHE in 7.5 M KOH for 18 h. Their OER activity are evaluated ex-situ using linear sweep voltammetry ... -
Tailoring the oxide surface composition of stainless steel for improved OER performance in alkaline water electrolysis
Zamanizadeh, Hamid Reza; Sunde, Svein; Pollet, Bruno; Seland, Frode (Peer reviewed; Journal article, 2022)There is a strong desire to replace bulk nickel electrodes for oxygen evolution reaction (OER) with a cheaper and more active steel material in alkaline water electrolyser (AWE). However, implementing an activation procedure ...
