Open the CIPO recordAbstract From the Canadian patent
A hydrogen storage composition has a hydrogenated state and a dehydrogenated state; in the hydrogenated state the composition comprises a metallic hydride having a metallic component which reversibly forms the hydride and a metallic heat transfer medium in intimate contact with the hydride which transfers heat to the hydride for dehydrogenation; in use hydrogen is liberated from the composition with transfer of heat to the heat transfer medium, the hydrogenated state may be regenerated by exposing the composition in a dehydrogenated state to hydrogen gas. In this way a source of hydrogen gas is provided which source may be regenerated.

Why it's free to use
- Filed November 7, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 7, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 7, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
