Method for Obtaining Hydrogen, and Corresponding Device

摘要

A first aspect of the invention relates to a method for obtaining highly pure hydrogen from a raw gas. Said method begins with heating and/or treating a semipermeable material made of metal or a metal alloy, preferably, conducting an electric current through the semipermeable material at the beginning of the method in order to increase the quantity of hydrogen passing through the material. The invention further relates to a device for obtaining highly pure hydrogen from the raw gas, said device comprising a semipermeable material which forms a boundary between the interior of a pressure vessel and the outer region of the pressure vessel and which is permeable to hydrogen. Said device is designed such that is can be heatable or treatable at least in sections, in particular, by means of electric energy.

1. A method for obtaining high-purity hydrogen from a raw gas, wherein the raw gas is passed under pressure into a first pressure vessel and this first pressure vessel is at least partially delimited from a second pressure vessel by a semipermeable material and the first pressure vessel is completely self-contained relative to the second pressure vessel, wherein the high-purity hydrogen segregates through the semipermeable material into the second pressure vessel, and wherein the semipermeable material is a metal or metal alloy, the semipermeable material is heated at the start of the method at least, for a period sufficient to increase the amount of permeating hydrogen, and the heating is at least interrupted.
