Electrolysis for hydrogen production

Membrane-less water electrolyzer

Hydrogen production through water electrolysis is a clean option for storing energy from renewable sources. Low-cost hydrogen production requires efficient water electrolyzers that can produce pure hydrogen at high production throughput. Membrane-less electrolyzers are promising technologies for hydrogen production due to their simple design, low ionic resistance, and adaptability to various working conditions. The fluidic flow keeps hydrogen and oxygen bubbles separated from each other in these electrolyzers. Bubbles’ motion in these electrolyzers affects product purity and electrochemical performance. Therefore, a thorough understanding of the two-phase flow is needed to improve the performance of membrane-less electrolyzers.
