Experimental studies and modeling of a 250-kW alkaline water electrolyzer for hydrogen production

A Guide to Electrocatalyst Stability Using Lab-Scale Alkaline Water Electrolyzers

“…15 More protocols are necessary for specific electrolyzer evaluations, including separator stability and degradation mechanism studies. 13,16,23 We hope our work inspires further standardization efforts, advancing toward a comprehensive comparison platform in AWE.…”

“…A substantial challenge in AWE research is the lack of standardized protocols. Unlike PEM electrolysis and fuel cell research, ,,− the AWE community still lacks standardized procedures for cell configurations, device assembly, accelerated stress tests, reference materials, and reporting data. Despite noteworthy efforts, ,, the scarcity of standardized lab-scale alkaline electrolyzer protocols impedes precise comparisons and reproducibility, leading to several groups creating custom architectures and employing unique testing conditions .…”

Green economic analysis for multi‐energy system with linearized CO2 electrolysis model

“…The byproduct hydrogen flow rate produced during the reaction and the water flow rate for the anodic oxygen evolution reaction (OER) [29] are shown in (10) and (11), respectively.…”

“…Ref. [10] proposes a semi-empirical model to describe the behaviour of a real-scale alkaline electrolyser system. While a simulation model of an industrial alkaline water electrolyser plant based on parameter-adjustable dynamic mass and energy balances is developed in ref.…”

Nanoelectrocatalysts for Anodic Oxygen Evolution in Acid: A Review

“…Therefore, the development of efficient hydrogen production and storage methods is a key step to realize the hydrogen economy. Although hydrogen production through alkaline electrolysis is already a commercialized method, , its cost is still much higher than that of traditional hydrogen production methods such as coal gasification and steam-methane reforming. The gross cost is expected to be competitive in the global market if it is below $2.0 kg –1 .…”
