Abstract
The present disclosure is generally related to providing thin hydrogen separation membranes coated on porous substrates that are useful in membrane steam reformers and methods for making same. These reformers can be integrated with protein exchange membrane (PEM) fuel cells to form power systems.
Claims49
A method for providing a hydrogen separation membrane 6 upon a substrate, comprising;
- providing a substrate having at least one surface;
- and
- disposing upon said at least one surface a composition and forming a leak-tight coating utilizing said composition, wherein said leak-tight coating provides permeance of hydrogen therethrough, thereby forming said hydrogen separation membrane 6 upon said substrate.
A membrane reformer comprising:
- a thin leak-tight coating disposed upon a substrate, wherein said leak-tight coating transports hydrogen and said thin leak-tight coating is comprised of at least one of palladium, palladium alloys or palladium and silver alloy.
Dependencies are inferred from the claim text.
