An apparatus for removing free hydrogen from a gas mixture containing essentially hydrogen, oxygen, and steam using a catalyst arrangement for catalytically supported oxidation of hydrogen and a hydrogen-storage device for absorption of hydrogen by hydride formation. The catalyst arrangement and the hydrogen-storage device are designed to operate in different temperature and pressure regions, and they are arranged to provide good heat conduction between them. In this manner, heat generated by hydride formation enhances catalytic oxidation.

Why it's free to use
- Filed November 22, 1994 and granted February 9, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 22, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 22, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
