Brief Description

Pure water is typically used to prepare aqueous electrolytes for water electrolysis. However, large-scale hydrogen production using water electrolysis requires a substantial quantity of high-quality water, which increases process costs due to the need for water treatment. Moreover, such demand places additional stress on drinking water resources, particularly in water scarce regions such as arid zones of India. To address these challenges, utilizing untreated natural water sources, such as seawater and surface water, for electrolysis offers an economical alternative. Unfortunately, conventional membrane-based electrolysers are not suitable for operation with impure water electrolytes. In this context, this project aims to develop a membraneless flow water electrolyser that leverages flow dynamics to avoid the crossover of H 2 and O 2 gases generated at the cathode and anode, respectively. Our goal is to design a scalable electrochemical device suitable for practical deployment rather than limiting the work to a laboratory scale prototype.
