Abstract
A supported membrane for separation of hydrogen in a fuel cell includes a microetched foil to form a substrate. The supported membrane also includes a membrane metal of a metal alloy deposited over the substrate to form a thin metal supported membrane for hydrogen separation.
Claims18
A supported membrane for separation of hydrogen in a fuel cell comprising:
- a microetched foil to form a substrate;
- and
- a membrane metal of a metal alloy deposited over said substrate to form a thin metal supported membrane having a thickness of between about one micrometer and ten micrometer for hydrogen separation.
A method of making a thin metal supported membrane useful as a diaphragm in fuel reformers for separating hydrogen from other gaseous products of a reforming reaction, said method comprising the steps of:
- providing a substrate comprising a microetched foil;
- and
- depositing a membrane metal of a metal alloy onto the substrate to form a thin metal supported membrane having a thickness of between about one micrometer and ten micrometer for hydrogen separation.
