Abstract
A nickel-mischmetal-calcium compound is used to store gaseous hydrogen at pressures up to about 15 atmospheres at ambient temperatures. The Ni.sub.5 M.sub.1-y Ca.sub.y compounds have values of y ranging from about 0.2 to about 0.9. Alloys conforming to this formula contain from about 4% to about 27% mischmetal, from about 2% to about 11% calcium, up to about 15% copper, and the balance essentially nickel.
