Hydrogen membrane development

Membranes which can separate hydrogen from other gasses at high temperature are an essential “enabling technology” for the H₂MR. Starting from an inexpensive commercial ceramic (alumina ) supports we are able to fabricate reproducibly membranes with thin metal layers (<5µm) which are permeable only to hydrogen.

Palladium membranes

A palladium membranes can be used to produce a pure hydrogen. Palladium is a material which can rapidly take-up and transport large quantities of hydrogen but is impermeable to other gasses. To separate hydrogen from a mixture of gasses a pressure difference over the membrane is applied. the hydrogen flows through the membrane if there is a difference in hydrogen partial pressure between the feed and permeate side.
