초록

This invention describes a solution to the particular problem of liquid water formation in hydrogen getters exposed to quantities of oxygen. Water formation is usually desired because the recombination reaction removes hydrogen without affecting gettering capacity and the oxygen removal reduces the chances for a hydrogen explosion once free oxygen is essentially removed. The present invention describes a getter incorporating a polyacrylate compound that can absorb up to 500% of its own weight in liquid water without significantly affecting its hydrogen...

청구항

What is claimed is: 1. A hydrogen getter composition for removing hydrogen and liquid water formed as the result of a hydrogen/oxygen catalysis, comprising: an organic polymer having unsaturated carbon-carbon bonds; a hydrogenation catalyst distributed throughout said getter composition wherein said hydrogenation catalyst is in reactive association with said unsaturated carbon-carbon bonds; and a liquid water absorbing polyacrylate distributed throughout said getter composition, for absorbing liquid water. 2. The hydrogen getter composition of claim...
