Abstract
A method is provided for the preparation of metal/porous substrate composite membranes by flowing a solution of metal to be plated over a first surface of a porous substrate and concurrently applying a pressure of gas on a second surface of the porous substrate, such that the porous substrate separates the solution of metal from the gas, and the use of the resulting membrane for the production of highly purified hydrogen gas.

A method for producing a metal plated porous substrate, comprising:
- flowing a solution of metal to be plated over a first surface of a porous substrate with pores having a diameter in a range from 5 to 200 nanometers and
- concurrently applying a pressure of gas on a second surface of the porous substrate opposite to said first surface, such that said porous substrate separates the solution of metal from the gas.
A method for producing a metal plated porous substrate, comprising:
- flowing a solution of metal to be plated over a first surface of a porous ceramic substrate and
- concurrently applying a pressure of gas on a second surface of the porous ceramic substrate opposite to said first surface, such that said porous ceramic substrate separates the solution of metal from the gas.
A method for producing a metal plated porous substrate, comprising:
- flowing a solution of metal to be plated over a first surface of a porous substrate, wherein said porous substrate is a cylindrical substrate having an inner surface and an outer surface and
- concurrently applying a pressure of gas on a second surface of the porous substrate opposite to said first surface, such that said porous substrate separates the solution of metal from the gas.
A method for producing a metal plated porous substrate, comprising:
- flowing a solution of metal to be plated over a first surface of a porous substrate, wherein said porous substrate comprises a layer of porous ceramic on a layer of porous metal and
