A membrane for separating hydrogen from a gas mixture is provided on at least one side with a catalyst layer for a specific catalytic combustion process. A methanol reformation system so equipped can be brought rapidly to operating temperature, with the hydrogen-separating membrane being heated directly by performing the catalytic combustion process.

[ What is claimed is:] [1.]1. A coated membrane for a hydrocarbon reformation system, comprising:a membrane for separating hydrogen from a gas mixture; anda coating on at least one side of the hydrogen separating membrane, said coating comprising a layer of a combustion catalyst for catalyzing combustion of a gas stream, wherein said layer is a porous layer or a structured layer leaving uncoated areas of the surface of said at least one side of the hydrogen separating membrane. [5.]5. A methanol reformation system, comprising:a hydrogen-separating stage for separating hydrogen from a reformate gas, wherein the hydrogen separating stage comprises a hydrogen separating membrane coated on at least one side with a layer of a combustion catalyst, wherein said layer is a porous layer or a structured layer leaving uncoated areas of the surface of said at least one side of the hydrogen separating membrane. [11.]11. A method for operating a methanol reformation system, comprising:providing a hydrogen separating membrane in said methanol reformation system, said hydrogen separating membrane having a layer of a combustion catalyst on at least one side thereof, wherein said layer is a porous layer or a structured layer leaving uncoated areas of the surface of said at least one side of the hydrogen separating membrane;during a cold start, before an operating temperature of the system is reached, subjecting the catalyst layer to a gas stream flow; andcatalytically combusting the gas stream, thereby heating the hydrogen separating membrane to the operating temperature.12. A method according to claim 11, further comprising:providing a catalytic burner in thermal communication with a reformation reactor chamber;supplying fuel to the catalytic burner; andcatalytically combusting the fuel, thereby heating the reformation reaction chamber to the operating temperature.
