Stable Catalyst Layers for Hydrogen Permeable
Composite Membranes
Colin A. Wolden and J. Douglas Way
Summary: A hydrogen permeable membrane that is stable over a broad temperature range
Description: There is great interest in using high temperature membranes in devises to produce
high purity hydrogen from a variety of sources. Current hydrogen permeable membranes
employ a palladium catalyst layer on both sides of a hydrogen permeable metal or metal alloy.
However, at elevated temperatures (>350C) the palladium catalyst layer diffuses into the
metal membrane, dramatically deceasing its ability to separate hydrogen. This invention is of a
hydrogen separation membrane that is based on nonporous composite metal carbide or metal
sulfide coated membranes capable of high flux and permselectivity for hydrogen. This
membrane is capable of being operated over a broad temperature range, including at elevated
temperatures, while maintaining hydrogen selectivity.
