Design and Characterisation of an Alkaline Electrolyser

Alkaline electrolysis has been gaining considerable attention lately as a viable method for producing green hydrogen from renewables. Researchers are currently focusing on improving electrolysers, for example, by trying to increase their dynamic performance and efficiency. New designs with improved components are introduced for this purpose. This paper proposes a simple and easy-to-manufacture electrolyser design made from readily available materials. The components are easy to disassemble and can be replaced by new or degraded components to assess their impact. Characterisation of the small single cell 10 W electrolyser gave consistent results, even after interchanging parts.
