PYROTECHNIC PROCESS FOR PROVIDING VERY HIGH PURETY HYDROGEN AND ASSOCIATED DEVICE

摘要

A pyrotechnic process for providing very high purity hydrogen, includes the combustion of at least one solid pyrotechnic charge capable of generating hydrogen-containing gas for the production of a pressurized hot hydrogen-containing gas that contains at least 70% by volume of hydrogen; and the purification of at least one portion of the pressurized hydrogen-containing gas, by passing through a metallic hydrogen separation membrane maintained at a temperature above 250° C., in order to obtain, at the outlet of the membrane, a hydrogen-containing gas that contains at least 99.99% by volume of hydrogen.

1. A pyrotechnic process for providing very high purity hydrogen, comprising:
combusting at least one solid pyrotechnic charge capable of generating hydrogen-containing gas for the production of a pressurized hot hydrogen-containing gas that contains at least 70% by volume of hydrogen; and purifying at least one portion of said pressurized hydrogen-containing gas, by passing through a metallic hydrogen separation membrane maintained at a temperature above 250° C., advantageously between 300° C. and 600° C., in order to obtain, at the outlet of said membrane, a hydrogen-containing gas that contains at least 99.99% by volume of hydrogen.
