A proton-conductive membrane for electrochemical applications, particularly for use in fuel cells, is provided. The membrane consists of a polymer based on a base polymer, other than a vinyl polymer, which includes aromatic rings and also sulfonic acid groups which are bound covalently directly to the aromatic rings of the base polymer, that is, without spacer groups therebetween.

Proton conductive membrane for electromechanical applications

In a method for the separation of supercritical gas from substances dissolved in the gas with a membrane through which the gas passes while the substances dissolved in the gas is retained, a pore-free membrane of a polymer perfluoro-2,2-diemthyl-1,3-dioxole is used as a membrane in the separation process.

Method for high-pressure gas separation

A method of removing organic compounds from an air/permanent gas mixture. This mixture, as untreated medium, is conveyed to a first gas separation membrane and is divided into a filtrate gas stream that is concentrated with organic compounds and a retained gas stream that is depleted of organic compounds. The concentrated filtrate is conveyed to a recovery device for the recovery of organic compounds therefrom. The pressure of the air/permanent gas mixture is raised prior to entry thereof into the first gas separation membrane. The pressure of the concentrated filtrate is reduced after exit thereof from the first gas separation membrane. The depleted gas stream is discharged into the atmosphere, and the gas stream that exits the recovery device is returned to the air/permanent gas mixture at some point subsequent to the pressure increase thereof.
