If you like playing with rattlesnakes, Lithium Hydride melts at 680 C and
with electrolysis liberates Hydrogen at the anode.
"For example, on the electrolysis of fused lithium hydride, the hydrogen is liberated at the positive electrode (i.e. a negatively charged hydrogen ion is discharged), and not the negative electrode as is the case when water is electrolysed."
A metal can pressurized with argon perhaps?
