Hydrogen Membrane

‌Working Principle

When a mixture of two or more gases passes through a polymer membrane, differences in the solubility and diffusion coefficients of each gas in the membrane cause varying permeation rates. Under the driving force of the pressure difference on both sides of the membrane, gases with faster permeation rates, such as water vapor, hydrogen, and carbon dioxide, pass through the membrane first and are enriched. Gases with slower permeation rates, such as methane, nitrogen, and carbon monoxide, are retained on the other side, achieving the separation of the gas mixture.



Features of Hydrogen Membrane



•  The separation membrane is made of high-polymer hollow fibers.

•  These hollow fiber membranes are extremely fine hollow tubes that can withstand high pressure without support materials.

•  The outer diameter of the fibers is about 0.2-0.4mm, and the inner diameter is 0.1-0.2mm, maintaining shape under high pressure.

•  High effective membrane surface area per unit volume, with good chemical and physical stability.

•  Long lifespan, typically over 6 years.

•  High efficiency, low cost, compact size, and lightweight.
